Cov qauv ntawm cov roj carbon hlau thiab coils tsuas yog suav nrog cov ncauj lus kom ntxaws ntawm lawv cov tshuaj muaj pes tsawg leeg, cov txheej txheem kho tshuab thiab cov txheej txheem tsim khoom.
Tshuaj Muaj Tshuaj
Lub Cheebtsam tseem ceeb ntawm cov roj carbon hlau thiab coils suav nrog cov pa roj carbon monoxide xws li cov pa roj carbon (C) Tshwj xeeb, cov ntsiab lus carbon yog feem ntau nruab nrab ntawm {{}}}}. 4%, cov ntsiab lus phosphorus yog tsawg dua {{11 {11}}. 045%, thiab cov Sulphur cov ntsiab lus tsawg dua 0.045%. Cov ntsiab lus ntawm cov ntsiab lus no muaj qhov tseem ceeb uas cuam tshuam rau lub zog, kev nruj thiab vuam kev ua haujlwm ntawm cov hlau phaj.
Cov Khoom Siv Neeg Kho Tshuab
Cov cuab yeej siv cov khoom siv ntawm cov roj carbon hlau daim hlau thiab coils tsuas yog suav nrog lub zog zog, tensile lub zog, elongation thiab kev cuam tshuam todualness. Tensile cov kev ntsuam xyuas tuaj yeem ntsuas cov txiaj ntsig lub zog thiab lub zog tensile, muaj lub zog thiab cov yas ntawm cov hlau phaj; Kev ntsuas kev cuam tshuam tau raug siv los xyuas qhov tawv ntawm cov hlau steel nyob rau hauv kev cuam tshuam loads; Cov kev ntsuam xyuas nyuaj ntsuas lub hardness ntawm cov hlau phaj, thiab cov siv feem ntau yog brinell hardness, rockwell hardness thiab vickers hardness. Ib qho ntxiv, metallographic qauv tsom xam tuaj yeem saib lub microstructure ntawm cov hlau phaj, xws li ferrite, hlaws thiab bainite, los ntsuas nws ua tau zoo thiab ua tau zoo. Cov txheej txheem tsim khoom lag luam ntawm cov txheej txheem tsim khoom ntawm cov roj carbon hlau thiab coils suav nrog shearing, leveling, sib sau, ncaj thiab nplaim txiav. Thaum lub sij hawm tsim kev tsim khoom, ntau yam cov tsis muaj kev tswj hwm kom ntseeg tau tias qhov ua tau zoo thiab ua tau zoo ntawm cov khoom uas yuav tsum tau siv. Cov txheej txheem tsim khoom lag luam yuav sib txawv raws li cov chaw tsim tshuaj paus thiab cov khoom lag luam tshwj xeeb, feem ntau yuav tsum tau tswj hwm nruj thiab ntsuas.
