Cov khoom siv siv

Cov ntawv thov hauv kev lag luam steelmaking:

Deoxidation

Nws yog ib qho tseem ceebdeoxidizerHauv cov txheej txheem statmaking. Vim tias muaj kev muaj zog sib thooj ntawm silicon thiab cov pa roj ntsha tau ntxiv rau cov pa roj oxygen rau hauv cov pa roj oxygen (sitening) Piv txwv li, hauv zus tau tej cov lc hlau thiab alloy steel, lc fesi 65 thiab 72 tuaj yeem ua lub luag haujlwm deoxidation zoo.

Alloying Ua Haujlwm

Raws li ib tugalloying additive, silicon tuaj yeem txhim kho cov khoom siv me me ntawm cov hlau xws li lub zog, hardness, thiab kev txwv ywj. Thaum tsim hluav taws xob hlau, cov kabmob steel thiab lwm cov hlau thiab lwm yam cov hlau ferrosilicon tuaj yeem kho cov hlau thiab txhim kho cov hlau. Nyob rau tib lub sijhawm, vim nws cov ntsiab lus carbon qis, nws yuav tsis muaj qhov cuam tshuam tseem ceeb ntawm cov hlau, uas yog tshwj xeeb tshaj rau kev tsim cov roj carbon hlau thiab cov roj carbon tsawg.
