Kev piav qhia ntxaws txog kev siv thawj zaug
Raws li cov pa roj carbon additive hauv kev lag luam metallurgical: Qhov no yog ib qho ntawm cov kev siv tseem ceeb ntawm calcined anthracite. Thaum lub sij hawm hluav taws xob rauv steelmaking lossis casting txheej txheem, kev tswj xyuas cov ntsiab lus ntawm cov pa roj carbon monoxide hauv cov hlau los yog hlau yog qhov tseem ceeb. Calcined anthracite, nrog nws cov ntsiab lus siab ruaj khov (txog 95% lossis ntau dua) thiab qis sulfur thiab phosphorus qib, ua haujlwm zoo tshaj carbon- ntxiv cov khoom. Nws tuaj yeem nqus tau zoo rau hauv cov hlau molten, txhim kho cov khoom siv ntawm cov khoom kawg.
Raws li cov khoom siv raw hauv cov pa roj carbon thiab tshuaj lom neeg kev lag luam: Calcined anthracite yog cov khoom siv tseem ceeb rau kev tsim cov khoom siv carbon xws li electrode paste (siv hauv cov hluav taws xob hluav taws xob). Nws kuj tseem ua cov pa roj carbon tseem ceeb rau kev tsim cov calcium carbide (CaC₂), uas yog cov khoom siv tseem ceeb rau kev lag luam tshuaj acetylene.
Raws li cov khoom pom: Hauv kev kho dej, calcined anthracite feem ntau ua tiav rau hauv lim xov xwm ntawm qhov loj me me (piv txwv li, 1-5 mm). Nws cov hardness siab, ntom, thiab tshuaj ruaj khov ua rau nws muaj txiaj ntsig zoo rau cov impurities hauv cov tso tsheb hlau luam pom, muab kev pabcuam ntev.
