1.Yintoni iHot Rolled Steel Material Grades
Intsimbi yintsimbi yentsimbi equlethe ixabiso elincinci lekhabhoni. Iimveliso zentsimbi ziza kumabakala ahlukeneyo ngokusekelwe kwipesenti yekhabhoni eziquletheyo. Iiklasi ezahlukeneyo zentsimbi zihlelwe ngokweziqulatho zazo zekhabhoni. Amanqanaba entsimbi aqengqelekayo ahlelwa ngokwala maqela alandelayo ekhabhoni:
Ikhabhoni ephantsi okanye intsimbi ethambileyo iqulethe i-0.3% okanye ngaphantsi kwekhabhoni ngomthamo.
Intsimbi ephakathi kwekhabhoni iqulethe i-0.3% ukuya kwi-0.6% yekhabhoni.
Iintsimbi eziphezulu zekhabhoni ziqulethe ngaphezu kwe-0.6% yekhabhoni.
Izixa ezincinci zezinye izinto zokudibanisa ezifana nechromium, imanganese okanye i-tungsten nazo zongezwa ukuvelisa amanqanaba amaninzi entsimbi. Amanqanaba entsimbi ahlukeneyo abonelela ngeepropathi ezininzi ezizodwa njengamandla okuqina, i-ductility, malleability, ukuqina, kunye nokuhanjiswa kwe-thermal kunye nombane.
2.Umahluko phakathi kweNtsimbi eQithiweyo eHotyo kunye neNtsimbi eQiniweyo ebandayo
Uninzi lweemveliso zetsimbi zenziwa ngeendlela ezimbini eziphambili: i-hot rolling okanye i-cold rolling. Intsimbi eshushu eqengqelekayo yinkqubo yokusila apho intsimbi icolwa khona kubushushu obuphezulu. Ngokuqhelekileyo, iqondo lobushushu lentsimbi eqengqelekayo lingaphezulu kwe-1700°F. Intsimbi epholileyo yinkqubo apho intsimbi icinezelwe kwiqondo lokushisa.
Kubalulekile ukuba uqaphele ukuba zombini intsimbi eshushu eshushu kunye nentsimbi epholileyo ayiwona amabakala ensimbi. Zizo iindlela zokwenziwa kwangaphambili ezisetyenziselwa iintlobo ezahlukeneyo zeemveliso zetsimbi.
Inkqubo yeNtsimbi eQingiweyo
Intsimbi eshushu esongwayo ibandakanya ukwenza kunye nokuqengqeleka amacwecwe entsimbi abe ngumtya omde ngeli xesha ifudunyezwa ngaphezu kowona bushushu buphezulu. I-slab ebomvu-eshushu isondliwa ngoluhlu lwee-roll ze-roll ukuze zenze kwaye zolule ibe ngumgca omncinci. Emva kokuqulunqwa kugqityiwe, umgca wensimbi upholiswe ngamanzi kwaye ulimele kwikhoyili. Amazinga ahlukeneyo okupholisa amanzi aphuhlisa ezinye iimpawu zetsimbi kwintsimbi.
Ukuqhelanisa intsimbi eshushu egobileyo kwindawo yobushushu begumbi ivumela ukonyuka kwamandla kunye ne-ductility.
Intsimbi eshushu eqengqelekayo iqhele ukusetyenziselwa ulwakhiwo, iingoma zikaloliwe, iishidi lesinyithi, kunye nezinye izinto ezingadingi kugqitywa okunomtsalane okanye iimilo ezichanekileyo kunye nokunyamezelana.
Inkqubo yeNtsimbi eQedayo
Intsimbi epholileyo esongwayo iyafudunyezwa kwaye ipholiswe njengentsimbi eshushu esongwayo kodwa iphinde iqhubekeke kusetyenziswa i-annealing okanye ukuqengqeleka komsindo ukuphuhlisa amandla aphezulu kunye namandla esivuno. Umsebenzi owongezelelweyo kunye nexesha lokucubungula longeza kwiindleko kodwa livumela ukunyamezela okusondeleyo kunye nokubonelela ngeendlela ezininzi zokugqiba. Olu hlobo lwensimbi lunokugqiba olulula kwaye lusetyenziswa kwizicelo ezifuna imeko ethile yendawo kunye nokunyamezela komlinganiselo.
Ukusetyenziswa okuqhelekileyo kwentsimbi epholileyo epholileyo kubandakanya iinxalenye zesakhiwo, ifenitshala yentsimbi, izixhobo zasekhaya, iinxalenye zemoto kunye nezicelo zobugcisa apho ukuchaneka okanye i-aesthetics iyimfuneko.
3.Hot Rolled Steel amaBanga
Intsimbi eshushu esongwayo iyafumaneka kumabakala amaninzi ukuhlangabezana neenkcukacha zeprojekthi yakho. I-American Society for Testing and Materials (ASTM) okanye i-Society of Automotive Engineers (SAE) ibeka imigangatho kunye namabakala ngokwesakhiwo somzimba wesinyithi kunye nobuchule.
Amanqanaba entsimbi ye-ASTM aqala ngonobumba “A” omele iintsimbi ezinentsimbi. Inkqubo yokuhlela ye-SAE (ekwabizwa ngokuba yi-American Iron and Steel Institute okanye inkqubo ye-AISI) isebenzisa inombolo eneedijithi ezine zokuhlela. Amanqanaba e-carbon steel ePlain kule nkqubo aqala ngedijithi ye-10, elandelwa zii-integers ezimbini ezibonisa i-carbon concentration.
Oku kulandelayo ngamabakala aqhelekileyo ensimbi eshushu. Nceda uqaphele ukuba ezinye iimveliso zinikezelwa kwiinketho zombini ezishushu kunye nezibandayo.
