Ukususela ekubunjweni ukuya kwifom, uluhlu lwezinto ezichaphazela iimpawu zemveliso yensimbi engenasici. Enye yezona zinto zibalulekileyo eziqwalaselwayo kukuba yeyiphi ibakala lentsimbi enokusetyenziswa. Oku kuya kugqiba uluhlu lweempawu kwaye, ekugqibeleni, zombini iindleko kunye nobomi beemveliso zakho zensimbi engenasici.
Ngoko wazi njani ukuba uqale phi?
Ngelixa isicelo ngasinye sahlukile, le mibuzo isi-7 ibalaselisa iingqwalaselo ezibalulekileyo zokukunceda ucuthe iinketho zakho kwaye ufumane amabanga alungele iimfuno okanye isicelo sakho.
1. LUYIFUNA LUPHI UHLOBO LWENKCAZELO YAM?
Xa ucinga ngensimbi engenasici, izinto zokuqala ezifikayo engqondweni mhlawumbi zixhathisa i-acids kunye nekloridi-ezifana nezo zifumaneka kwi-industrial applications okanye kwiindawo zaselwandle. Nangona kunjalo, ukuxhathisa ubushushu kuyingqwalasela ebalulekileyo ngokunjalo.
Ukuba ufuna ukuxhathisa kwe-corrosion, uya kufuna ukuphepha i-ferritic kunye ne-martensitic steels. Amanqaku afanelekileyo ensimbi engenasici kwiindawo ezinobungozi abandakanya i-austenitic okanye i-duplex alloys efana nebakala 304, 304L, 316, 316L, 2205, kunye ne-904L.
Kwiindawo ezinobushushu obuphezulu, amabakala e-austenitic ahlala elungile. Ukufumana ibakala elinechromium ephezulu, isilicon, initrogen, kunye nezinto ezinqabileyo zomhlaba kuya kutshintsha ngakumbi amandla entsimbi ukumelana nobushushu obuphezulu. Amanqaku aqhelekileyo kwiindawo zobushushu obuphezulu aquka i-310, i-S30815, kunye ne-446.
Amabakala ensimbi ye-Austenitic nawo afanelekile kwiindawo eziphantsi kweqondo lokushisa okanye i-cryogenic. Ukongezwa kokuchasana, unokujonga kwikhabhoni ephantsi okanye amabakala aphezulu enitrogen. Amabakala aqhelekileyo kwiindawo ezinobushushu obuphantsi aquka i-304, 304LN, 310, 316, kunye ne-904L.
2. INGABA INTSHUMAYELO YAM KUFUNEKA SIFIKE?
Intsimbi enokwakheka okulambathayo iya kuba brittle ukuba isebenze kakhulu kwaye inikeze ukusebenza okuphantsi. Kwiimeko ezininzi, iintsimbi ze-martensitic azikhuthazwa. Ngaphaya koko, intsimbi enokwakheka okuphantsi ayinakuyibamba imilo yayo xa kufuneka ukwakheka okuntsonkothileyo okanye okuntsonkothileyo.
Xa ukhetha ibakala lentsimbi, uya kufuna ukuqwalasela uhlobo ongathanda ukuba lihanjiswe ngayo. Nokuba ufuna iintonga, ii-slabs, imivalo okanye amashiti aya kunqanda ukhetho lwakho. Ngokomzekelo, iintsimbi ze-ferritic zivame ukuthengiswa kumaphepha, iintsimbi ze-martensitic zihlala zithengiswa kwimivalo okanye kwi-slabs, kunye ne-austentic steels zifumaneka kuluhlu olubanzi lweefom. Amanye amabakala ensimbi afumaneka kwiifom ezahlukeneyo abandakanya i-304, i-316, i-430, i-2205, kunye ne-3CR12.
3. INGABA INGXEBI YAM KUYA KUFUNA UTSHINTSHO?
Umatshini awuyongxaki. Nangona kunjalo, ukuqina komsebenzi kunokuvelisa iziphumo ebezingalindelekanga. Ukongezwa kwesulfure kunokuphucula ukucwangciswa kwe-machina kodwa kunciphisa ukubunjwa, i-weldability kunye nokumelana nokubola.
Oku kwenza ukuba ukufumana ulungelelwaniso phakathi kobuchule kunye nokumelana nomhlwa kube yingqwalaselo ebalulekileyo kwiinkqubo ezininzi zokwenza insimbi engenasici. Ngokuxhomekeke kwiimfuno zakho, amabakala 303, 416, 430, kunye ne-3CR12 anika ibhalansi elungileyo apho unokucutha khona ukhetho olungakumbi.
4. INGABA KUFUNEKA NDITSHISHE INTSIMBI YAM ENGENASINZULU?
I-Welding steel stainless ingakhokelela enkathazweni-kuquka ukuqhekeka okutshisayo, uxinzelelo lwe-corrosion cracking, kunye ne-intergranular corrosion-kuxhomekeke kwibakala lentsimbi esetyenzisiweyo. Ukuba uceba ukuwelda intsimbi yakho engenasici, iialloys ze-austenitic zifanelekile.
Amabakala ekhabhoni aphantsi anokunceda ngakumbi ngokudibanisa ngelixa izongezo, ezinjenge-niobium, zinokuzinzisa i-alloys ukuphepha inkxalabo yokubola. Amabakala aziwayo ensimbi engenasici kwi-welding abandakanya i-304L, i-316, i-347, i-430, i-439 kunye ne-3CR12.
5. INGABA KUYAFUNEKA UNYANGO LWEBUSHUSHU?
Ukuba isicelo sakho sidinga unyango lobushushu, kufuneka uqwalasele indlela amabakala ahlukeneyo entsimbi aphendula ngayo. Iimpawu zokugqibela zeentsimbi ezithile zihluke kakhulu ngaphambi nangemva kokunyanga kobushushu.
Kwiimeko ezininzi, iintsimbi ze-martensitic kunye nemvula, ezifana ne-440C okanye i-17-4 PH, zinika umsebenzi ongcono kakhulu xa uphathwa ukushisa. Iintsimbi ezininzi ze-austenitic kunye ne-ferritic azikho lukhuni xa sele ziphathwe ubushushu kwaye ke azikho iindlela ezifanelekileyo.
6. NGAWAMAPHI AMANDLA WENsimbi ANGAPHAMBILI KWISICELO SAM?
Amandla entsimbi yinto ebalulekileyo ekufuneka iqwalaselwe ukwandisa ukhuseleko. Ukanti, ukuhlawulela ngokugqithiseleyo kunokukhokelela kwiindleko ezingeyomfuneko, ubunzima, nezinye izinto eziyinkcitho. Iimpawu zamandla zibekwe ngokukhululekileyo yintsapho yentsimbi kunye neenguqu ezingaphezulu ezikhoyo kumabakala ahlukeneyo.
7. YIYIPHI IINDLEKO EZIPHAKAMILEYO KUNYE NEINDLEKO ZOBOMI BOBOMI LWESI SENSIMBI KUMMBONISO WAM?
Zonke iingqwalasela zangaphambili zondla kumbuzo obaluleke kakhulu ekukhetheni ibakala lensimbi engenasici-ixabiso lobomi. Ukufanisa amabakala ensimbi engenasici kwindawo yakho ekujoliswe kuyo, ukusetyenziswa kunye neemfuno, unokuqinisekisa ukusebenza okuhlala ixesha elide kunye nexabiso elikhethekileyo.
Qaphela ukuba uhlalutye indlela intsimbi eya kwenza ngayo ngexesha elijoliswe kuyo kwaye zeziphi iindleko ezinokuthi zibandakanyeke ekugcinweni okanye ekutshintsheni ngaphambi kokuthatha isigqibo. Ukunciphisa iindleko kwangaphambili kunokubangela inkcitho engaphezulu kakhulu kubomi beprojekthi yakho, imveliso, ulwakhiwo, okanye olunye usetyenziso.
