Silicon hlau hmoov, raws li ib qho tseem ceeb muaj raw khoom, plays lub luag hauj lwm tseem ceeb nyob rau hauv lub teb ntawm refractories. Nws daim ntawv thov yuav muaj kev cuam tshuam rau kev ua haujlwm ntawm cov khoom siv refractory.

Ferro-tungsten ntau lawm txoj kev yog agglomeration txoj kev, hlau extraction txoj kev thiab txhuas tshav kub txoj kev.

Calcium silicate cored hlau (CaSi Cored Wire) yog ib hom cored hlau siv hauv steelmaking thiab casting daim ntaub ntawv. Nws yog tsim los ua kom paub meej cov nyiaj calcium thiab silicon rau hauv molten hlau los pab hauv deoxidation, desulphurization thiab alloying. Los ntawm kev txhawb cov kev cuam tshuam tseem ceeb no, cored hlau txhim kho qhov zoo, huv si thiab cov khoom siv kho tshuab ntawm cov hlau.

Vanadium yog ib qho tseem ceeb alloying ntsiab feem ntau siv hauv kev lag luam steel. Vanadium-muaj steel muaj cov khoom zoo xws li lub zog siab, siab tawv, thiab hnav tsis kam, yog li nws yog dav siv hauv tshuab, tsheb, nkoj tsim, railways, aviation, txuas hniav, tshuab hluav taws xob, kev tiv thaiv kev lag luam thiab lwm yam lag luam.

Cov txheej txheem ntau lawm ntawm cov pa roj carbon tsawg thiab nruab nrab ferromanganese feem ntau suav nrog electrosilicon thermal method, rocker method thiab oxygen blowing method.

Dub silicon carbide yog tsim los ntawm quartz xuab zeb thiab roj av coke silica ua cov ntaub ntawv tseem ceeb los ntawm kev kub kub smelting nyob rau hauv lub qhov cub tsis kam. Nws hardness yog nruab nrab ntawm corundum thiab pob zeb diamond, nws lub zog txhua yam yog siab dua corundum, thiab nws yog nkig thiab ntse. Ntsuab silicon carbide yog tsim los ntawm roj av coke thiab silica raws li cov ntaub ntawv tseem ceeb, nrog ntsev ntxiv ua ib qho ntxiv, thiab smelted ntawm qhov kub thiab txias nyob rau hauv lub qhov cub tsis kam. Nws hardness yog nruab nrab ntawm corundum thiab pob zeb diamond, thiab nws lub zog txhua yam yog siab dua corundum.
