SM400C Steel phaj yog lub siab - kev kawm nruj, tsim los rau hauv qis {3} {{leading applicions.
Nws muaj qhov tsawg kawg los lub zog lub zog ntawm 245 MPa, tensile lub zog ntawm 400-510 MPA, thiab chaw tsim hluav taws xob, kev lag luam tshuab, thiab kev lag luam hauv vaj tse, thiab Civil system, thiab Civilary Constrastructure tej yaam num.
Cov hlau cov ntsiab lus muaj roj carbon tsawg thiab tswj cov ntsiab lus tso tawm muab nwsZoo tshaj Weldability, ductility, thiab formability, tso cai ua kom muaj txiaj ntsig, khoov, tho qhov dej, thiab kev sib dhos thaum kev tsim kho lossis kev tsim khoom siv rau kev tsim khoom. Nws cov khoom siv kho txhua yam thiab kev ua kom nruj ua rau SM400C muaj kev ntseeg siab, tus nqi siv tau zoo rau kev siv hluav taws xob ib puag ncig.

Kev tsim khoom thiab Forging txheej txheem ntawm SM400C Steel phaj
Melting & Casting
SM400C yog tsim nyob rau hauv lub cub hluav taws xob hauv hluav taws xob (EAF) lossis cov pa roj oxygen (bof), qhov twg nyoos. Alloy cov ntsiab lus xws li manganese thiab silicon tau ntxiv kom ua tiav cov tshuaj muaj kuab yam xav tau. Molten steel yog ces muab pov rau hauv cov pob zeb lossis cov tsiaj.
Cua sov / rheater
Tus pob zeb pob zeb yog rhuab rau 1,100-1,250℃hauv lub cub tawg los npaj rau kub dov. Qhov no ua kom muaj qhov kub thiab txias rau kub thiab txhim kho ductility rau kev lom zem.
Kub Rolling / Forging
Lub tshuab ziab mos muag yog dhau los ntawm cov xaim mills ntau zaus kom ua tiav cov yam xav tau, dav, thiab cov khoom siv neeg kho mob. Muaj qee kis, Forging tshwj xeeb yuav tau thov kom tsim cov paib tuab lossis txhim kho grain qauv rau kev siv tawv heev.
Txias & Li Qub
Tom qab dov, cov paib yog txias rau hauv cov xwm txheej lossis ua kom zoo dua rau cov qoob loo ua kom zoo dua thiab txhim kho kev ua haujlwm txhua yam thiab cuam tshuam nyuaj.
Xov & Kev Soj Ntsuam
Daim phiaj yog txiav kom loj, ncaj, thiab saum npoo - ua tiav. Cov tshev mis zoo suav nrog kev ntsuas tshuaj lom neeg, Tensile, tawm los, elongation), thiab cuam tshuam kev ntsuas ntawm -20℃rau SM400C.
Lub Ntim Kawg & Tus Me Nyuam
Lub tiav tiav daim phiaj yog bundled thiab tiv thaiv rau kev thauj mus los, ua kom muaj kev ncaj ncees rau nws cov khoom siv hluav taws xob thiab cov khoom siv zoo thaum tuaj txog ntawm kev tsim kho lossis Fabrication chaw.
