He maha ngā tāngata e hoko ana i te maitai kore waikura kua oti kē te whakaoti, ā, ka nui ake te uaua o te rauemi me whai whakaaro ngā kaiwhakahaere.
Pērā i te nuinga o ngā rauemi, he maha ngā painga me ngā ngoikoretanga o te maitai kore waikura. Ka kiia he "maitai kore waikura" te maitai mēnā kei roto i te koranu te 10.5% te iti rawa o te chromium, e hanga ana i tētahi paparanga waikura e ātete ana ki te waikawa me te waikura. Ka taea te whakapai ake i tēnei ātete waikura mā te whakanui ake i te ihirangi chromium me te tāpiri i ētahi atu tāpiringa koranu.
Nā ngā āhuatanga o te rauemi "kowiri tira", te iti o te tiaki, te pakari me ngā momo whakaotinga mata, he mea pai mō ngā ahumahi pēnei i te hanga whare, ngā taonga whare, te kai me te inu, te hauora me te maha atu o ngā tono e hiahia ana kia kaha me te ātete ki te waikura pērā i te rino.
He nui ake te utu o te maitai kore waikura i ētahi atu maitai. Heoi, he pai ake te kaha ki te taumaha mā te whakamahi i ngā rauemi angiangi atu i ngā momo maitai noa, ā, ka taea te penapena moni. Nā te utu whānui, me whakarite ngā toa e whakamahi ana i ngā taputapu tika hei karo i te moumou moni nui me te mahi anō i tēnei rauemi.
Ko te maitai kore waikura he uaua ki te whakarewa nā te mea ka tere te mimiti i te wera, ā, me tino tupato i te wā e whakaoti ana, e whakakanapa ana hoki.
Ko te mahi me te maitai kore waikura he tikanga me whai kaiwhakarewa, kaiwhakahaere rānei he nui ake te wheako i te mahi me te maitai waro, he mea pumau ake. Ka taea te whakaiti i tōna whānui mā te whakauru i ētahi tawhā, inā koa i te wā e whakarewa ana. Nā te nui o te utu o te maitai kore waikura, he pai ake mā ngā kaiwhakahaere he nui ake te wheako ki te whakamahi.
"Ko te tikanga ka hokona e te tangata te maitai kore waikura nā te mea he pai ōna āhua," te kī a Jonathan Douville, te kaiwhakahaere hua matua, R&D International, Walter Surface Technologies, Pointe-Claire, Que. "Ko te tikanga ka hokona e te tangata te maitai kore waikura nā te mea he pai ōna āhua," te kī a Jonathan Douville, te kaiwhakahaere hua matua, R&D International, Walter Surface Technologies, Pointe-Claire, Que. «Люди обычно покупают нержавеющую сталь из-за ее отделки», — сказал Джонатан Доувилль, старший мдрудпо, International Walter Surface Technologies, Pointe-Claire, Que. "Ko te tikanga ka hokona e te tangata he kowiri tira hei whakaotinga," te kī a Jonathan Douville, Kaiwhakahaere Hua Matua, R&D International, Walter Surface Technologies, Pointe-Claire, Que."Ko te tikanga ka hokona e te tangata he kowiri tira hei whakaoti," te kī a Jonathan Douville, te kaiwhakahaere matua o te rangahau me te whanaketanga o te ao i Walter Surface Technologies i Pointe Claire, Quebec. "Ka tāpiri atu tēnei ki ngā here me whai whakaaro ngā kaiwhakahaere."
Ahakoa he paninga kakano raina rahi 4, he paninga whakaata rahi 8 rānei, me whakarite e te kaiwhakahaere he ngawari te papanga ki te papanga, ā, kāore te paninga e pakaru i te wā e whakahaeretia ana, e tukatukahia ana hoki. Ka taea hoki e ia te whakawhāiti i ngā kōwhiringa whakarite me te horoi, he mea nui ēnei ki te hanga wāhanga kounga.
"I te wā e mahi ana koe me tēnei rauemi, ko te mea tuatahi me mahi ko te whakarite kia ma, kia ma, kia ma anō," te kī a Rick Hathelt, Kaiwhakahaere Rohe PFERD mō Kanata, Ontario, Mississauga, Ontario. "He mea tino nui kia whakarite kia ma te hau (kore waro) i te wā e horoi ana i te maitai kore waikura hei tango i ngā poke ka puta ai te waikura (te waikura) ā muri ake nei, ā, kia kore ai e ora anō te paparanga passivation mā te hanga i tētahi paparanga tiaki hei whakaiti i te waikura."
Mēnā ka whakamahia te kowiri tira, me horoi te rauemi me te taiao. He tīmatanga pai te tango i te hinu me ngā toenga kirihou mai i ngā rauemi. Ka taea e ngā poke i runga i te kowiri tira te whakapōrearea, engari ka taea hoki e rātou te hanga raruraru i te wā e whakarewa ana, ā, ka puta he hapa. Nō reira, he mea nui kia horoia te mata i mua i te whakarewanga.
Kāore te taiao o te awheawhe i te tino ma i ngā wā katoa, ā, ka raru pea te whakawhiti parahanga ina mahi ana me te maitai kore waikura me te maitai waro. He maha ngā wā ka whakamahia e te toa he maha ngā pā hau, ka whakamahia rānei he hauhautanga hei whakamatao i ngā kaimahi, ka panaia pea ngā parahanga ki runga i te papa, ka puta rānei he maturuturu, he hauhautanga rānei ki runga i ngā rauemi mata. He tino uaua tēnei ina pupuhihia ngā matūriki maitai waro ki runga i te maitai kore waikura. He mea nui te wehewehe i ēnei rauemi me te penapena i roto i te taiao ma ina tae mai ki te whakarewanga whai hua.
He mea nui kia tangohia te tae koretake kia kore ai e hanga waikura i roto i te wā, kia ngoikore ai te hanganga whānui. He pai hoki te tango i te kikorangi kia ōrite ai te tae o te mata.
I Kanata, nā te tino makariri me ngā āhuatanga o te hotoke, he mea tino nui te whiriwhiri i te kounga tika o te maitai kore waikura. I whakamārama a Douville i te tīmatanga i whiriwhiria e te nuinga o ngā toa te 304 nā tōna utu. Engari, ki te whakamahia e te toa tēnei rauemi ki waho, ka tūtohu rātou kia huri ki te 316 ahakoa he rua te utu. Ka ngawari te waikura o te 304 ina whakamahia, ina rongoatia rānei ki waho. Ahakoa kua horoia te mata, ā, ka hangaia he paparanga whakakore, ka taea e ngā āhuatanga o waho te pā ki te mata, ka whakangaro i te paparanga whakakore, ā, i te mutunga ka waikura anō.
"He mea nui te whakarite mō te whakarewatanga mō ētahi take matua," te kī a Gabi Miholix, Tohunga Whakawhanake Taupānga, Abrasive Systems Division, 3M Canada, Rānana, Ontario. "He mea nui te tango i te waikura, te peita me ngā papa whakarara mō te whakarewatanga tika. Me kore he poke i te mata whakarewa ka ngoikore ai te hononga."
E kī ana a Hatelt he mea tika te horoi i te wāhi, engari ko te whakarite i mua i te whakarewatanga ka uru pea ki te whakakoi i te rauemi kia tika ai te piri me te kaha o te whakarewatanga.
I te wā e whakarewahia ana te maitai kore waikura, he mea nui kia whiriwhiria te konganuku whakakī tika mō te momo e whakamahia ana. He tino tairongo te maitai kore waikura, ā, me whakamanahia ngā whakarewa mō te momo rauemi kotahi. Hei tauira, me whakamahi te konganuku turanga 316 i te konganuku whakakī 316. Kāore e taea e ngā kaiwhakarewa te whakamahi noa i tētahi momo konganuku whakakī, me whakamahi ia momo maitai kore waikura i tētahi whakakī motuhake hei whakarewa tika.
"I te wā e whakarewa ana i te maitai kore waikura, me aro tonu te kaiwhakarewa ki te pāmahana," te kī a Michael Radaelli, te kaiwhakahaere hua mō Norton | Saint-Gobain Abrasives, Worcester, Massachusetts. "He maha ngā momo taputapu ka taea te whakamahi hei ine i te pāmahana o te whakarewa me te wāhanga i te wā e wera ana te kaiwhakarewa, nā te mea ki te puta he kapiti i roto i te maitai kore waikura, ka tata pakaru te wāhanga."
I tāpiri atu a Radaelli me whakarite te kaiwhakarewa kia kaua ia e noho roa ki te wāhi kotahi. He huarahi pai te whakarewa maha-paparanga hei ārai i te wera nui o te papa. Mā te whakarewa roa o te maitai kore waikura ka wera rawa, ka pakaru.
"Ka roa ake te wā e whakarewa ai i te maitai kore waikura, engari he mahi toi anō hoki e hiahia ana ki ngā ringa mātau," te kī a Radaelli.
Ko te whakarite i muri i te whakarewanga e whakawhirinaki ana ki te hua whakamutunga me tōna whakamahinga. I ētahi wā, e ai ki tā Miholix, kāore te whakarewanga e kitea, nō reira he iti noa te horoinga i muri i te whakarewanga e hiahiatia ana, ā, ka tere te tango i ngā paru e kitea ana. Me whakataurite rānei, me horoi rānei te whakarewanga, engari kāore he whakaritenga motuhake e hiahiatia ana. Mena e hiahiatia ana he whakaotinga pai, he whakaotinga whakaata rānei, me whai mahi whakakanapa matatau ake pea. Kei te whakamahinga anake.
"Ehara i te tae te raruraru," te kī a Miholic. "Ko tēnei rerekētanga o te mata e tohu ana kua rerekē ngā āhuatanga o te konganuku, ā, tera pea ka waikura/waikura."
Mā te whiriwhiri i tētahi taputapu whakaoti tere rerekē ka penapena wā me te moni, ā, ka taea hoki e te kaiwhakahaere te whakarite i te whakaotinga.
He mea nui kia tangohia te tae koretake kia kore ai e hanga waikura i roto i te wā, kia ngoikore ai te hanganga whānui. He pai hoki te tango i te kikorangi kia ōrite ai te tae o te mata.
Ka taea e te tukanga horoi te kino i ngā mata, inā koa ka whakamahia ngā matū kaha. Mā te horoi hē ka ārai i te hanganga o tētahi paparanga kore e taea te whakamahi. Koia te take e taunaki ana te nuinga o ngā tohunga kia horoia ā-ringa ēnei wāhanga kua whakarewaina.
"Mēnā ka horoia ā-ringa, ki te kore e tukua te hāora kia tauhohe ki te mata mō ngā hāora 24, 48 rānei, kāore he wā hei hanga i tētahi mata kore mahi," te kī a Douville. I whakamārama ia me whai hāora te mata kia tauhohe ki te chromium i roto i te koranu hei hanga i tētahi paparanga kore mahi. I ētahi toa, he tikanga te horoi, te tākai i ngā wāhanga, me te tuku tonu atu, ka whakaroa i te tukanga, ka whakanui ake i te tūponotanga o te waikura.
He maha ngā rauemi e whakamahia ana e ngā kaihanga me ngā kaiwhakarewa. Heoi, e ai ki te kōrero i mua ake nei, he iti noa ngā herenga o te whakamahinga o te maitai kore waikura. He taahiraa tuatahi pai te tango i te wā ki te horoi i te wāhanga, engari he pai anake te āhua o te taiao e noho ana.
I kī a Hatelt kei te kite tonu ia i ngā mahi poke. Ko te mea nui ko te whakakore i te waro i roto i te taiao mahi maitai kore waikura. Ehara i te mea onge mō ngā toa e whakamahi ana i te maitai te huri ki te maitai kore waikura me te kore e whakarite tika i te taiao mahi mō tēnei rauemi. He hapa tēnei, ina koa mēnā kāore e taea e rātou te wehewehe i ngā rauemi e rua, te hoko rānei i ā rātou ake taputapu.
"Mēnā he paraihe waea tāu hei huri, hei whakarite rānei i te maitai kore waikura, ā, ka whakamahia e koe ki te maitai waro, kāore e taea te whakamahi i te maitai kore waikura," te kī a Radaelli. "Kua poke ngā paraihe i te waro me te waikura. Ki te poke whakawhiti ngā paraihe, kāore e taea te horoi."
Me whakamahi motuhake ngā toa i ngā taputapu mō te whakarite rauemi, engari me tapa hoki ngā taputapu he "kowiri tira anake" hei karo i te poke koretake, e ai ki tā Hatelt.
Me whai whakaaro ngā toa mahi ki ngā āhuatanga maha i te wā e whiriwhiri ana i ngā taputapu whakarite mō te whakarewa kowiri tira, tae atu ki ngā kōwhiringa whakamarara wera, te momo kohuke, te tere, me te rahi o te kōhao.
"He tīmatanga pai te whiriwhiri i tētahi mea whakakoi kua pania ki te wera," te kī a Miholix. "He tino mārō te maitai kore waikura, ā, he nui ake te wera e puta mai ana i te wā e huri ana i te maitai ngawari. Me haere te wera ki tētahi wāhi, nō reira he paninga e taea ai e te wera te rere ki te taha o te kōpae, kaua e noho tonu ki te wāhi e huri ana koe. I taua wā he tino pai rawa atu."
Ko te whiriwhiri i te momo mea whakakoi ka whakawhirinaki ki te āhua o te whakaotinga whānui, tāna tāpiri. He mea tino kitea i roto i te kanohi o te kaimātakitaki. Ko ngā kohuke alumina i roto i ngā mea whakakoi te momo tino noa e whakamahia ana i roto i ngā mahi whakaotinga. Hei hanga i te kowiri tira kia kikorangi te mata, me whakamahi te kohuke silicon carbide. He koi ake, ā, he hohonu ake ngā tapahi e whakaata ana i te māramatanga rerekē, ka kikorangi. Mena kei te rapu te kaiwhakahaere i tētahi whakaotinga mata motuhake, ahurei rānei, he pai ake te kōrero ki te kaiwhakarato.
"He raru nui te RPM," te kī a Hatelt. "He rerekē ngā RPM e hiahiatia ana mō ngā taputapu rerekē, ā, he tere rawa te oma. Mā te whakamahi i te RPM tika ka puta ngā hua pai rawa atu, e pā ana ki te tere o te mahi me te kounga. Kimihia te otinga e hiahiatia ana e koe, me pēhea hoki te ine."
I tāpiri atu a Douville ko te haumi ki ngā taputapu whakaoti tere rerekē tētahi huarahi hei whakaoti rapanga tere. He maha ngā kaiwhakahaere e whakamahi ana i te huri noa hei whakaoti, engari he tere teitei anake mō te tapahi. Me whakaroa te whakaoti i te tukanga. Mā te whiriwhiri i tētahi taputapu whakaoti tere rerekē ka penapena wā me te moni, ā, ka taea e te kaiwhakahaere te whakarite i te whakaoti.
He mea nui anō hoki te kirikiri ina whiriwhiria he kirikiri. Me tīmata te kaiwhakahaere me te kirikiri pai rawa atu mō te whakamahinga.
Ka tīmata me te kirikiri 60, 80 rānei (waenga), ka taea e te kaiwhakahaere te peke ki te kirikiri 120 (pai) me te kirikiri 220 (tino pai) tata tonu, ka eke ki te tuawhā o ngā taumata mō te maitai kore waikura.
"Tērā pea e toru noa ngā taahiraa," te kī a Radaelli. "Heoi, ki te mea he nui ngā whakarewa e mahia ana e te kaiwhakahaere, kāore e taea e ia te tīmata me te kirikiri 60, 80 rānei, ā, ka taea e ia te whiriwhiri i te kirikiri 24 (tino taratara) 36 rānei (taratara). Ka tāpirihia he taahiraa anō tēnei, ā, ka uaua pea. Tangohia ngā karawarawa hōhonu i roto i te rauemi."
Hei tāpiri, ko te tāpiri i tētahi rehu ārai-piripiri, i tētahi tiēre rānei hei hoa pai mā te kaiwhakarewa, engari he maha ngā wā ka warewarehia i te wā e whakarewa ana i te maitai kore waikura, e ai ki a Douville. Me tango ngā wāhanga kua piripiri, ka taea e ēnei te rakuraku i te mata, me ētahi atu mahi kirikiri, ā, ka roa ake te wā. Ka taea te whakakore ngāwari i tēnei mahi mā te pūnaha tiaki piripiri.
