Tsawg Carbon Ferro Chrome

Ferrochrome yog ferro alloy uas muaj chromium thiab hlau. Nws yog ib qho tseem ceeballoy additiverau steelmaking. Cov ntsiab lus ntawm cov pa roj carbon tsawg ferrochrome yog {{0}}.15 ~ 0.50%. Feem ntau yog siv los tsim cov khoom nruab nrab thiab qis carbon steel, carburizing steel, thiab tsim cov iav. Qhov qis dua cov ntsiab lus ntawm ferrochrome, qhov nyuaj dua nws yog ua kom zoo dua qub, siv hluav taws xob ntau dua, thiab nce tus nqi.

Cov chromium hauv steel yog ntxiv sivferrochrome. Tsawg-carbon ferrochrome muaj qhov ntom ntom thaum siv, tab sis nws muaj zog thiab zoo rigidity; nws tuaj yeem txhim kho oxidation tsis kam ntawm cov hlau thiab ua kom cov hlau tsis muaj zog; Nyob rau tib lub sijhawm, nws muaj peev xwm tsis tshua muaj cua sov, ceev ceev ceev, thiab kev ua haujlwm zoo tuag-casting.

Nws yuav tsum raug sau tseg tias qis carbon ferrochrome muaj 30% roj (tsuas yog N2 thiab H2). Thaum siv rau steelmaking, cov roj no yuav ntab ntawm qhov sib cuam tshuam ntawm cov hlau molten thiab slag, ua rau cov combustion poob ntawm chromium. Txo cov nqi rov qab; hlau-chromium-muaj npuas tuaj yeem ua rau cov hlau tsis zoo thaum crushing thiab ntim. Kev kho lub tshuab nqus tsev ntawm cov pa roj carbon tsawg ferrochrome yog txheej txheem casting uas txo cov roj alloy cov ntsiab lus. Muab lub molten hlau ladle uas muaj kua ferrochrome rau hauv lub tshuab nqus tsev chamber. Tom qab sealing, siv lub tshuab nqus tsev twj tso kua mis kom khiav tawm li ntawm 5 mus rau 7 feeb, thiab lub tshuab nqus tsev nqus mus txog 10.6 kPa txog 13.3 kPa. Tom qab ntawd tawg lub tshuab nqus tsev, tshem tawm lub molten hlau ladle, thiab nrum nws dua kom ua tiav lub hom phiaj ntawm kev txo cov inclusions thiab gases, ua rau saum npoo du thiab tiaj tus, thiab txo qhov tawg thiab ntim khoom poob.
