Ukususela ekubunjweni ukuya kwimo, izinto ezahlukeneyo zichaphazela iimpawu zeemveliso zentsimbi engagqwaliyo. Enye yezona zinto zibalulekileyo ekufuneka ziqwalaselwe kukuba loluphi uhlobo lwentsimbi omele ulusebenzise. Oku kuya kumisela uluhlu lweempawu, kwaye ekugqibeleni, iindleko kunye nobomi bemveliso yakho yentsimbi engagqwaliyo.
Ngoko ke wazi njani ukuba uqale phi?
Nangona isicelo ngasinye sahlukile, le mibuzo isi-7 igxininisa izinto ezibalulekileyo ezinokukunceda unciphise ukhetho lwakho kwaye ufumane amanqaku afanelekileyo kwiimfuno okanye isicelo sakho.
1. LUHLOBO LUPHI LOKUNGAXHANYI INTSIMBI YAM OLUDINGAYO?
Xa ucinga ngentsimbi engagqwaliyo, izinto zokuqala eziza engqondweni mhlawumbi kukumelana nee-asidi kunye nee-chloride--ezifana nezo zifumaneka kwiindawo zoshishino okanye kwiindawo zaselwandle. Nangona kunjalo, ukumelana nobushushu nayo yinto ebalulekileyo ekufuneka uyiqwalasele.
Ukuba ufuna ukumelana nokugqwala, kuya kufuneka uziphephe iintsimbi ze-ferritic kunye ne-martensitic. Iintlobo zentsimbi engagqwaliyo ezifanelekileyo kwiindawo ezigqwalisiweyo ziquka ii-austenitic okanye ii-duplex alloys ezifana nee-grades 304, 304L, 316, 316L, 2205, kunye ne-904L.
Kwiindawo ezishushu kakhulu, amanqanaba e-austenitic adla ngokuba ngcono. Ukufumana amanqanaba ane-chromium ephezulu, i-silicon, i-nitrogen, kunye nezinto ezinqabileyo zomhlaba kuya kutshintsha ngakumbi amandla entsimbi okumelana nobushushu obuphezulu. Amanqanaba aqhelekileyo kwiindawo ezishushu kakhulu aquka i-310, i-S30815, kunye ne-446.
Iiklasi zentsimbi ye-Austenitic nazo zifanelekile kwiindawo ezinobushushu obuphantsi okanye eziguquguqukayo. Ukuze ufumane uxhathiso olongezelelekileyo, ungajonga kwiiklasi ze-carbon ephantsi okanye ze-nitrogen ephezulu. Iiklasi eziqhelekileyo kwiindawo ezinobushushu obuphantsi ziquka i-304, 304LN, 310, 316, kunye ne-904L.
2. INGABA INTSIMBI YAM KUFUNEKA IQUMELEKE?
Intsimbi engakwazi ukwakheka kakuhle iya kuba buthathaka ukuba isetyenzwa kakhulu kwaye inike ukusebenza okuphantsi. Kwiimeko ezininzi, iintsimbi ze-martensitic azikhuthazwa. Ngaphezu koko, intsimbi engakwazi ukwakheka kakuhle isenokungagcini imo yayo xa kufuneka ukwenziwa okuntsonkothileyo okanye okuntsonkothileyo.
Xa ukhetha uhlobo lwentsimbi, kuya kufuneka uqwalasele uhlobo ofuna ukuba ifike ngalo. Nokuba ufuna iintonga, iislabhu, iibhari okanye amaphepha kuya kuyithintela indlela onokukhetha kuyo. Umzekelo, iintsimbi ze-ferritic zihlala zithengiswa ngamashiti, iintsimbi ze-martensitic zihlala zithengiswa ngamashiti okanye ngamaslabhu, kwaye iintsimbi ze-austentic ziyafumaneka kwiintlobo ngeentlobo zeentlobo. Ezinye iintlobo zentsimbi ezikhoyo kwiintlobo ngeentlobo ziquka i-304, 316, 430, 2205, kunye ne-3CR12.
3. INTSIMBI YAM IZA KUFUNA UKUSEBENZA NGOMSHINI?
Umatshini awusoloko uyinkinga. Nangona kunjalo, ukuqinisa umsebenzi kunokuvelisa iziphumo ebezingalindelekanga. Ukongezwa kwesalfure kunokuphucula ukusebenza komatshini kodwa kunciphisa ukwakheka, ukudityaniswa kunye nokumelana nokugqwala.
Oku kwenza ukufumana ibhalansi phakathi koomatshini kunye nokumelana nokugqwala kube yinto ebalulekileyo ekufuneka iqwalaselwe kwiinkqubo ezininzi zokwenza intsimbi engagqwaliyo enezigaba ezininzi. Ngokuxhomekeke kwiimfuno zakho, amabakala angama-303, 416, 430, kunye ne-3CR12 anika ibhalansi elungileyo apho unokuncitshiswa khona ukhetho oluya phambili.
4. INGABA KUFUNEKA NDIWELISE INTSIMBI YAM ENGAGQIBELIYO?
Ukuwelda intsimbi engagqwaliyo kunokubangela ingxaki—kuquka ukuqhekeka okushushu, ukuqhekeka kokugqwala okuxineneyo, kunye nokugqwala okuphakathi kwe-granular—kuxhomekeke kudidi lwentsimbi esetyenzisiweyo. Ukuba uceba ukuwelda intsimbi yakho engagqwaliyo, ii-austenitic alloys zilungile.
Amanqanaba aphantsi ekhabhoni anokunceda ngakumbi ekudibaniseni ngelixa izongezo, ezifana ne-niobium, zinokuqinisa i-alloys ukuze kuthintelwe iingxaki zokugqwala. Amanqanaba athandwayo entsimbi engagqwaliyo yokuwelda aquka i-304L, 316, 347, 430, 439 kunye ne-3CR12.
5. INGABA KUYAFUNEKA UNYANGO LWESHUSHU?
Ukuba isicelo sakho sifuna unyango lobushushu, kufuneka uqwalasele indlela amanqanaba ahlukeneyo entsimbi asabela ngayo. Iimpawu zokugqibela zentsimbi ezithile zahlukile kakhulu ngaphambi nasemva konyango lobushushu.
Kwiimeko ezininzi, iintsimbi zokuqinisa i-martensitic kunye ne-precipitation, ezifana ne-440C okanye i-17-4 PH, zibonelela ngokusebenza kakuhle xa zinyangwa ngobushushu. Iintsimbi ezininzi ze-austenitic kunye ne-ferritic stainless azinakuqina xa zinyangwa ngobushushu kwaye ngenxa yoko azizo iindlela ezifanelekileyo.
6. YINTONI ENOBUNZIMA BENTSIMBI OBUNGELELEYO KWISICELO SAM?
Amandla entsimbi yinto ebalulekileyo ekufuneka iqwalaselwe ukuze kuphuculwe ukhuseleko. Sekunjalo, ukuhlawula ngokugqithisileyo kunokukhokelela kwiindleko ezingafunekiyo, ubunzima, kunye nezinye izinto ezichitha imali. Iimpawu zamandla zibekwe ngokukhululekileyo lusapho lwentsimbi kunye notshintsho olongezelelweyo olufumaneka kwiindidi ezahlukeneyo.
7. IYINTONI IXABISO ELIPHAMBILILEYO NEXABISO LOBOMI BONKE LALE NTSIMBI KWIMEKO YAM?
