Kev zamyog kev forging ntawm cov hlau ingot rau hauv billet nrog rauj lossis lub tshuab tshuaj ntsuab; raws li cov hlau muaj pes tsawg leeg tuaj yeem faib ua cov hlau thiab hlau

(1) Ntxiv rau cov hlau thiab carbon, cov tshuaj lom neeg muaj pes tsawg ntawm cov hlau hlau kuj muaj cov khoom sib xyaw ua ke, ntawm cov tub rog thiab phosphorus yog ib qho kev cuam tshuam implig. Manganese silico yog deoxidized ntsiab ntxiv rau cov hlau nplaum ntxiv rau cov hlau hauv cov txheej txheem ntawm steelmaking. Raws li cov ntsiab lus carbon sib txawv hauv cov hlau ua hlau, nws feem ntau muab faib ua ob hom hauv qab no:
Cov tshuaj ntsuab qis: Cov ntsiab lus carbon cov ntsiab lus yog 0.04% -0.25%;
Nruab nrab cov roj carbon hlau: 0.25% -0.55% cov ntsiab lus carbon;
Muaj Siab Carbon Hlau: Carbon Cov Ntsiab Lus Loj dua 0.55%
(2) Hlau Alloy yog ntxiv ib lossis ob peb cov khoom siv hluav taws xob zoo li no, kuj muaj lwm cov roj av alloy, kuj muaj lwm cov roj av alloy stungsten alloy steel muaj boron thiab nitrogen Lwm yam. Nonmetal cov ntsiab lus raws li tus nqi ntawm tag nrho cov ntsiab lus ntawm alloy keeb hauv hlau, tau muab faib ua peb pawg hauv qab no:

Tsawg Alloy Hlau: Tag nrho cov lus qhia cov ntsiab lus tsawg dua 3.5%;
Nruab Nrab Alloy Hlau: Tag nrho cov lus qhia tau yooj yim yog 3.5-10%;
High Alloy Alloy Hlau: Tag Nrho Cov Lus Qhia Tawm Tshiab yog ntau tshaj 10%
Raws li tus naj npawb ntawm cov khoom sib txawv uas muaj nyob hauv cov hlau nplaum, cov hlau roj av, cov roj ntsha, chromium molybdenum, tungsten vanadium steel thiab lwm yam
