Refractory Cib Rau Hluav Taws Xob Arc Rauv
Khoom Description
Kev xaiv cov cib refractory rau EAFs yog nyob ntawm cov yam ntxwv xws li hom hlau tsim, kev ua haujlwm kub, thiab cov kev cai tshwj xeeb ntawm lub tshuab tsim hluav taws xob. Kev txhim kho kom zoo, kev saib xyuas, thiab kev saib xyuas ntawm cov ntaub ntawv refractory yog qhov tseem ceeb rau kev ua tiav cov khoom siv hluav taws xob zoo thiab txhim khu kev qha hauv cov hluav taws xob arc rauv.

Hluav taws xob arc furnaces (EAFs) yog siv nyob rau hauv cov txheej txheem steelmaking kom yaj thiab ua kom zoo hlau seem siv hluav taws xob arc generated ntawm graphite electrodes thiab hlau nqi. Cov cua sov no ua haujlwm ntawm qhov kub thiab txias thiab xav tau cov ntaub ntawv refractory uas tuaj yeem tiv taus cua sov, tshuaj lom neeg, thiab kev ntxhov siab. Ntawm no yog cov hom refractory cib feem ntau siv hauv hluav taws xob arc rauv:
Magnesia-Carbon (MgO-C) cib:Cov cib no yog kev sib xyaw ua ke ntawm magnesia (MgO) thiab graphite, muab kev tiv thaiv zoo rau kev kub siab, tshuaj tua kab mob, thiab thermal shock. Lawv feem ntau siv nyob rau hauv EAF hauv ob sab phlu vim lawv cov kev ua tau zoo nyob rau hauv lub slag thiab hlau cheeb tsam.
Magnesia-Chrome (MgO-Cr2O3) Cib:Cov cib no muab cov magnesia thiab chrome rau txhim kho corrosion thiab yaig kuj. Lawv feem ntau siv nyob rau hauv EAF sidewalls thiab lwm qhov chaw raug rau corrosive los ntawm slag.
Alumina-Magnesia-Carbon (Al2O3-MgO-C) Cib:Cov cib no ua ke nrog alumina, magnesia, thiab carbon rau kev sib xyaw ua ke ntawm thermal kuj thiab corrosion kuj. Lawv siv nyob rau hauv qhov chaw uas slag thiab hlau tshwm sim.
Carbon Bricks:Carbon bricks yog siv nyob rau hauv EAF hearth linings, qhov uas lawv raug rau qhov kub siab tshaj plaws thiab hnyav tshuaj. Lawv muab cov thermal conductivity zoo thiab tiv thaiv slag nres.
