Cov Khoom Siv Refractory Twg ​​Xav Tau Rau Cov Converters?

Kev ua hlau rau lub tshuab hloov pauv yog cov txheej txheem tseem ceeb ntawm kev tsim hlau thiab hlau niaj hnub no, ua haujlwm nyob rau hauv cov xwm txheej hnyav heev - qhov kub txog li 1800 ° C, kev puas tsuaj ntawm cov hlau molten thiab cov khoom seem, kev xeb tshuaj lom neeg hnyav los ntawm slag, thiab kev poob siab thermal ntau zaus. Cov ntaub ntawv refractory zoo yog qhov tseem ceeb rau kev tiv thaiv lub plhaub converter, xyuas kom ruaj khov ntawm kev tsim khoom, txhim kho qhov zoo ntawm cov hlau, thiab txuas ntxiv lub neej ua haujlwm ntawm lub cub tawg. Hauv qab no yog cov lus qhia ntxaws ntxaws ntawm cov ntaub ntawv refractory tseem ceeb uas xav tau rau ntau thaj chaw ua haujlwm ntawm lub converter.

Cov cib Magnesia-carbon (MgO-C) yog cov khoom siv refractory tseem ceeb rau feem ntau thaj chaw hloov pauv, ua haujlwm ua lub hauv paus ua haujlwm tseem ceeb. Ua los ntawm cov magnesia fused purity siab, graphite zoo, phenolic resin binders, thiab cov tshuaj antioxidant, lawv ua ke qhov kev tiv thaiv slag zoo heev ntawm magnesia nrog rau qhov muaj zog tiv thaiv thermal ntawm graphite.

Cov qib sib txawv ntawm cov cib magnesia-carbon tuaj yeem hloov kho rau cov cheeb tsam tshwj xeeb:Cov cib magnesia-carbon uas muaj cov pa roj carbon ntau (muaj cov pa roj carbon 16-20%)siv rau hauv cov kab slag thiab trunnion thaj chaw kom tiv taus kev yaig hnyav, thaumcov qauv carbon nruab nrabyog tsim rau lub cub tawg sidewalls thiab molten pas dej ua ke.

Cov cib dolomite yog qhov kev xaiv pheej yig thiab zoo rau cov cheeb tsam uas muaj qhov xwm txheej ua haujlwm tsis hnyav, xws li hauv qab lub cub tawg thiab lub cev qis dua ntawm lub cub tawg. Ua los ntawm cov khoom sib xyaw ua ke ntawm calcium carbonate thiab magnesium carbonate, lawv muaj kev tiv taus alkaline slag zoo thiab feem ntau siv ua lwm txoj hauv kev pheej yig rau cov cib magnesia ntshiab.

Cov cib dolomite sib txuas nrog tar-bitumenyog qhov tshwj xeeb tshaj yog tsim rau cov ntaub linings mus tas li, muab kev rwb thaiv tsev thermal txhim khu kev qha thiab kev ruaj khov ntawm cov qauv.

Cov ntaub ntawv refractory ua haujlwm yog qhov tseem ceeb rau cov khoom siv hloov pauv tseem ceeb.Cov pob zeb permeable (cov cib permeable)siv rau hauv lub tshuab cua hauv qab, uas muaj cov qauv hlau-magnesia carbon sib xyaw ua ke kom ntseeg tau tias muaj roj txhaj tshuaj ruaj khov thaum lub sijhawm smelting.

Corundum refractory castables (Al₂O₃ cov ntsiab lus ≥90%)siv rau hauv cov chaw hnav khaub ncaws siab xws li qhov chaw tapping, muab kev tiv taus kub heev thiab kev tiv taus corrosion muaj zog.

Cov pam vov ua los ntawm cov khoom siv ...kuj yog cov khoom siv refractory tseem ceeb rau cov converters, feem ntau yog siv rau kev rwb thaiv tsev thermal ntawm lub qhov ncauj converter, flue, thiab lwm qhov. Mos thiab sib dua, lawv muaj kev tiv thaiv kub siab thiab kev ua haujlwm rwb thaiv tsev thermal zoo heev, uas tuaj yeem txo qhov poob cua sov, txo kev siv hluav taws xob, thiab txo qhov kev ntxhov siab thermal los ntawm kev hloov pauv kub ntawm lub cev cub kom tiv thaiv cov qauv cub.

Cov khoom sib xyaw ua ke thiab cov ntaub ntawv khokuj tseem ceeb heev, tswj kev ncaj ncees ntawm daim ntaub thiab txo cov sijhawm tsis tau npaj tseg.

Yog xav tau cov khoom siv refractory uas hloov kho raws li koj xav tau, thov hu rau peb pab neeg hnub no.
