Qhov sib txawv ntawm nruab nrab zaus furnace steelmaking thiab hluav taws xob arc rauv steelmaking:

1. cov nruab nrab zaus cua sov tsis tuaj yeem ua slag, yog li cov khoom tsis zoo xws li P thiab S tsis tuaj yeem raug tshem tawm, thaum lub tshuab hluav taws xob arc tuaj yeem ua tau;

2. Lub tshuab hluav taws xob nruab nrab tsis tuaj yeem tshuab pa kom txo tau cov pa roj carbon monoxide, yog li cov khoom C tsis tuaj yeem hloov kho downwards, tsuas yog carbon tuaj yeem nce ntxiv, thaum lub tshuab hluav taws xob arc tuaj yeem ua tau;

3. Lub tshuab hluav taws xob nruab nrab tsis tuaj yeem tshuab oxygen kom decarburize. Cov hlau muaj cov roj ntau thiab suav nrog xws li H ntsiab. Cov hlau muaj cov yam ntxwv hydrogen embrittlement, siab zog, qis elongation, thiab tsis tsim nyog plasticity, thaum hluav taws xob arc rauv yog qhov txawv.

4. Txawm tias smelting siab carbon steel, alloy cuab yeej hlau los yog castings, vim cov txheej txheem saum toj no tsis xws luag, qhov zoo ntawm cov hlau tseem tsis zoo li hluav taws xob rauv hlau, tab sis qee zaum nws tuaj yeem siv tau yog tias cov kev xav tau tsis siab.

5. Yog hais tias qhov nruab nrab zaus rauv yog nruab nrog tsim nyog refining chaw, nws tseem tuaj yeem tsim cov hlau zoo, txawm tias tshaj hluav taws xob arc rauv steelmaking. Cov txheej txheem tshwj xeeb tuaj yeem yog: nruab nrab zaus rauv + VOD + LF txheej txheem tuaj yeem tsim cov hlau zoo heev.
