Cov ntaub ntawv nyob hauv tsev yog cov ntaub ntawv tseem ceeb siv rau cov txheej txheem statmaking los tiv thaiv lub ladle cov yaig ntawm high-kub molten hlau thiab slag. Raws li lub thawv tseem ceeb rau tuav thiab thauj Molten Hlau (los ntawm Converter cov khoom siv tau ruaj khov, thaum cua sov hloov pauv thiab ua kom nruj ntawm cov nplais-steel interface. Cov hauv qab no yog cov khoom tseem ceeb, kev ua tau zoo thiab cov kev sib tw ntawm chav pw ua haujlwm refractory.

Fine vanadium pentoxide (v₂o₅ flake) yog ib daim ntawv ntawm vanadium pentoxide, uas yog golden lossis txiv kab ntxwv-daj flake muaj cov iav ruaj khov thiab cov khoom redox. Piv nrog cov hmoov, tus qauv flake tau muaj ntau dua crystallinity thiab zoo dua rau kev cia khoom thiab kev thauj mus los hauv high-kawg daim ntawv thov.

Refractory nozle yog cov khoom siv refractory siv rau cov hlau hluav taws xob siab (feem ntau yog cov hlau tsis muaj metall

Hauv kev lag luam steel niaj hnub, ntxiv rau ntawm cov ntsiab lus yog qhov tseem ceeb los txhim kho kev ua tau zoo ntawm cov hlau. Chromium, raws li ib qho tseem ceeb siv nyiaj ntau, tuaj yeem txhim kho cov corrosion tsis kam, hnav tsis kam thiab muaj kev ua haujlwm kub ntawm cov hlau. Cov roj carbon tsawg ntawm cov pa roj carbon Nws yog ib qho zoo alloy additive rau smelting stainless hlau, Alloy Steel thiab tshwj xeeb hlau.
