Refining tus neeg sawv cev tuaj yeem siv dav hauv cov hlau smelting thiab ua lag luam, nws yog ntau yam ntawm cov khoom siv smelting ntawm cov hlau. Nyob rau hauv cov txheej txheem smelting hlau deoxidation, desulfurization, phosphorus tshem tawm tuaj yeem tshem txhua hom kev tsis zoo, yog li cov hlau yog ntau dua.

Ntxiv cov neeg sawv cev ua kom muaj zog dua rau cov hlau ntxaij

Yog tias tseem nyob rau hauv cov txheej txheem smelting hlau yam tsis muaj kev tshem tawm cov roj thiab cov kab nrib pleb, kev sib cais, tawg, ua rau muaj kev tsis txaus siab, ua rau muaj kev poob qis hauv cov khoom lag luam zoo. Tom qab ntxiv cov neeg saib xyuas tau tshem tawm cov txheej txheem ua haujlwm tau pom hauv cov noob ua ke, txhim kho cov hlau, thiab ua raws li cov hlau, thiab ua raws sij hawm, thiab ua raws li cov hlau, thiab ua raws sijhawm rau cov hlau, thiab ua raws li cov hlau, thiab ua raws sij hawm, thiab ua raws li cov hlau, thiab ua raws li cov hlau, thiab ua raws sij hawm, thiab ua raws li cov hlau, thiab ua raws li cov hlau, thiab ua raws sijhawm rau cov hlau yaj.

Tsis tas li ntawd, nyob rau hauv cov txheej txheem smelting hlau yuav sib xyaw nrog ntau yam, sulfides, silicates, silicates, silicates, silicates no yuav raug tshem tawm cov khoom siv tshuab hluav taws xob ntawm cov hlau. Hauv cov txheej txheem smelting, yog tias cov kua hlau yog sib cuag nrog cov cua, yog li cov roj av tsis xws luag, yog li cov pa roj yuav tsum tau muab tshem tawm hauv lub sijhawm los txhim kho nws cov khoom siv.

Ntxiv tuaj yeem huv cov hlau yaj, kom ncav sijhawm rau hauv cov pa, uas pom tseeb, yog li txo cov ntsiab lus ntawm impurities hauv cov yaj. Qhov sib ntxiv ntawm cov neeg sawv cev tuaj yeem sib xyaw cov khoom seem, los ntawm kev sib xyaw ua kom tsis txhob muaj kev phom sij, porosity, nodules, cov tshuab ntxhua khaub ncaws thiab cov khoom tawg.

Refining tus neeg sawv cev yuav tsum tau siv ua raws li cov txheej txheem uas muaj kev sib xyaw ua ke, yog li koj tsis tuaj yeem cia siab tias yuav txo tau thiab deoxidation muaj peev xwm ua tau. Yog tias muaj cov kiav txhab thiab swb rau saum npoo thaum lub sijhawm smelting, qhov saum npoo ntab slag yuav tsum tau muab tshem tawm nyob rau lub sijhawm ua ntej pouring.
