Pure Hlau Billet:
Pure hlau billet yog cov khoom siv hlau uas muaj cov ntsiab lus carbon tsawg heev, feem ntau tsawg dua 0.03%. Nws yog tau los ntawm smelting hlau ore nyob rau hauv lub moj tej tawg rauv thiab yog yus muaj los ntawm nws siab purity, nrog ib tug hlau ntsiab lus ntawm ntau tshaj 99% thiab tsawg heev ntawm lwm yam ntsiab lus. Vim nws cov purity siab, ntshiab hlau billet ua ib qho tseem ceeb raw khoom rau kev tsim cov hlau zoo.
Txawm li cas los xij, txawm tias nws purity, ntshiab hlau billet muaj cov khoom siv tsis zoo, nrog tsis tshua muaj zog thiab toughness. Qhov no txwv nws cov ntawv thov kev lag luam, thiab nws feem ntau yog siv rau hauv cov xwm txheej tshwj xeeb xws li kev tsim cov hlau nplaum sib nqus. Cov txheej txheem ntau lawm ntawm cov hlau ntshiab hlau muaj ntau cov kauj ruam, suav nrog cov tshuab hluav taws xob smelting thiab converter ua, uas hloov cov hlau ore rau hauv cov hlau dawb huv.
Tsawg-Carbon Steel:
Cov pa roj carbon tsawg, tseem hu ua cov hlau me me, yog hom carbon steel nrog cov ntsiab lus carbon xws li 0.05% txog 0.25%. Vim nws cov ntsiab lus qis dua, cov pa roj carbon tsawg muaj qhov zoo dua hardness thiab toughness piv rau cov pa roj carbon zoo tib yam. Nws kuj pom zoo weldability thiab machinability, ua rau nws dav siv nyob rau hauv manufacturing mechanical qhov chaw, thav duab, steel hlau, thiab lwm yam kev siv.
Cov pa roj carbon tsawg muaj xws li cov pa roj carbon zoo tib yam steels thiab qee cov khoom siv zoo carbon steel. Ntau yam ntawm cov hlau no yog siv rau hauv engineering structural Cheebtsam yam tsis muaj kev kho cua sov, thaum lwm tus undergo carburizing thiab lwm yam kev kho cua sov rau cov neeg kho tshuab qhov yuav tsum tau hnav kuj. Cov pa roj carbon tsawg tuaj yeem dov rau hauv ntau yam duab xws li lub kaum sab xis steel, channel steel, I-beam steel, steel kav, steel strips, lossis steel phaj, uas yog siv los ua ntau yam khoom siv hauv tsev, ntim khoom, thawv, furnaces, thiab kev ua liaj ua teb. tshuab.
Kev tsim cov txheej txheem ntawm cov pa roj carbon tsawg yog zoo ib yam li lwm cov pa roj carbon steel. Ib txoj hauv kev yog kev sib txuas cov hlau ore thiab thee, melting lawv ua ke hauv lub qhov cub tawg, hloov qhov sib tov mus rau lwm lub qhov cub kom tshem tawm cov impurities thiab kho cov tshuaj muaj pes tsawg leeg, thiab tom qab ntawd ua kom cov hlau ua ib lub duab plaub. Cov hlau slab yog tom qab ntawd txo mus rau qhov xav tau loj siv cov txheej txheem kub dov lossis txias txheej txheem.
