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 ntau yam ntawm cov hlau thiab cov khoom siv tsis sib xws, kuj muaj lwm cov roj ntsha vanadium tunanium tungaluminate zirconium niobium Thiab tsis tshua muaj neeg nyob hauv ntiaj teb thiab lwm yam ntxiv, qee cov calcium alloy steel muaj raws li cov ntsiab lus ntawm alloy thiab nitrogen thiab lwm yam ntawm cov hlau, 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 kab hlau sib txawv, kuj tuaj yeem muab faib ua cov hlau sib txuas, raws li cov hlau aluminium, tuaj yeem muab faib ua manganese steel, chromium steel, boron steel, silicon steel, manganese steel hlau, chromalum hlau, chromium molybdenum, tungsten vanadium steel thiab lwm yam
