Kev siv Ferrochrome

Ferrochrome yog cov hlau tsis muaj hlau uas muaj chromium thiab hlau, uas yog qhov tseem ceeb ntawm aluminium alloy additive nyob rau hauv ironmaking. Raws li cov ntsiab lus sib txawv, ferrochrome muab faib ua cov pa roj carbon siab ferrochrome (cov ntsiab lus carbon yog 4 ~ 8 feem pua), nruab nrab carbon ferrochrome (cov ntsiab lus carbon yog 0.25 ~ 4 feem pua), cov pa roj carbon tsawg ferrochrome (carbon. cov ntsiab lus yog 0.15 ~ 0.45 feem pua ​​, micro-carbon ferrochrome (cov ntsiab lus carbon yog 0.01 feem pua), ultra-micro carbon ferrochrome (carbon Cov ntsiab lus tsawg dua 0.03 feem pua), nws yog xim hlau chromium, silicon nickel alloy, thiab lwm yam. Feem ntau silicon nickel alloy, nitriding chromium thiab lwm yam.

Micro - carbon chromite tseem ceeb rau kev tsim cov hlau stainless phaj, acid - resistant steel thiab hnav - resistant steel. Smelter txoj kev muaj xws li hluav taws xob silicon thermal txoj kev thiab thermal hloov txoj kev.

Nruab nrab thiab qis carbon ib puag ncig tus phooj ywg ferrochrome yog siv rau kev tsim cov khoom nruab nrab thiab qis carbon ib puag ncig tus phooj ywg alloy structural steel, manganese steel, alloy cuab yeej hlau.

High carbon steel ferrochrome (nrog rau ferrochrome recycled) siv tau:

(1) Raws li tus neeg sawv cev aluminium alloy rau pob steel, alloy steel thiab lub caij nplooj ntoos hlav steel nrog cov ntsiab lus siab carbon, nws tuaj yeem txhim kho kev ua tau zoo, hnav tsis kam thiab lub zog ntawm cov hlau;

(2) ua ib qho ntxiv rau npua hlau, txhim kho qhov hnav tsis kam thiab hardness ntawm npua hlau, thiab ua rau npua hlau muaj qhov kub thiab txias;

(3) Raws li magnesium-muaj raw khoom rau slag-dawb zus tau tej cov Si-Ni alloy thiab ntsug, qis thiab micro-carbon ferrochrome;

(4) raws li magnesium-muaj raw khoom rau kev tsim thiab tsim cov chromium hlau hauv electrolytic ntsev dej;

(5) raws li cov khoom siv raw rau stainless hlau phaj ntawm oxygen tshuab smelter.
