Refractory cib yog cov khoom siv ceramic uas feem ntau siv nyob rau hauv qhov kub thiab txias ib puag ncig vim nws tsis muaj combustibility thiab vim hais tias nws yog ib tug zoo insulator uas txo lub zog poob. Refractory cib feem ntau yog tsim los ntawm txhuas oxide thiab silicon dioxide. Nws tseem hu ua "fire brick."

Hlau casting yog ib qho txheej txheem qub uas tau ua qhov tseem ceeb rau tib neeg kev vam meej rau ntau pua xyoo. Los ntawm tsim intricate sculptures rau manufacturing complex indus

Ferrosilicon yog ib qho tseem ceeb ferroalloy dav siv nyob rau hauv steel metallurgy thiab foundry kev lag luam. Kab lus no yuav qhia meej txog cov txheej txheem tsim khoom ntawm ferrosilicon, suav nrog kev xaiv cov khoom siv raw, cov txheej txheem tsim khoom, cov txheej txheem ntws, kev tswj kom zoo thiab kev cuam tshuam ib puag ncig.

Lub alloy yog ib qho sib tov los yog cov kua nplaum uas muaj cov hlau. Ib yam li ntawd, ferroalloy yog cov khoom sib xyaw ntawm txhuas sib xyaw nrog lwm cov khoom xws li manganese, alum.

Silicon hlau hmoov yog ib qho tseem ceeb hauv kev lag luam steelmaking. Nws yog dav siv los ua tus neeg sawv cev alloying hauv kev tsim ntau hom hlau. Nrog nws cov khoom tshwj xeeb thiab cov txiaj ntsig, silicon hlau hmoov ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom zoo thiab kev ua haujlwm ntawm cov khoom hlau. Tsab ntawv xov xwm no yog npaj los muab kev tshawb nrhiav qhov tob ntawm silicon hlau hmoov rau steelmaking, qhia txog nws cov yam ntxwv, kev siv, thiab qhov zoo uas nws muaj rau kev lag luam steel.
