Khoom Taw qhia

Khoom Description

Nyob rau hauv cov ntsiab lus ntawm lub qhov cub tawg, cov khoom siv refractory tau ua tib zoo xaiv raws li cov kev ua haujlwm tshwj xeeb thiab cov ntaub ntawv ua tiav. High-alumina cib, silica cib, thiab lwm yam tshwj xeeb refractories feem ntau siv vim lawv muaj peev xwm ua tau raws li qhov xav tau ntawm blast furnace linings.

Mullite bricks for blast furnace

Hloov chaw, qhov cub tawg feem ntau siv cov khoom tshwj xeeb refractory, xws li high-alumina cib los yog silica cib, vim lawv cov kev tiv thaiv zoo tshaj rau cov xwm txheej hnyav pom nyob rau hauv lub qhov cub tawg. Cov xwm txheej no suav nrog qhov kub thiab txias tshaj li 2, 000 degrees Celsius, raug rau cov hlau molten thiab slag, nrog rau cov cua kub hauv qhov cub.

Cov ntsiab lus tseem ceeb rau cov khoom siv refractory siv nyob rau hauv blast furnaces muaj xws li:

Resistance rau Thermal Shock: Cov ntaub ntawv hauv ob sab phlu yuav tsum muaj peev xwm tiv taus qhov kub thiab txias hloov sai thiab thermal cycling tsis tawg lossis tawg.

Tshuaj tiv thaiv: Refractories siv nyob rau hauv blast furnaces yuav tsum tau heev resistant rau tshuaj tua kab mob los ntawm molten hlau, slag, thiab lwm yam corrosive tshuaj generated thaum lub sij hawm ironmaking txheej txheem.

Mechanical Strength: Cov ntaub ntawv no yuav tsum muaj lub zog txhua yam txaus los txhawb qhov hnyav ntawm lub nra (hlau ore, coke, thiab limestone) thiab txhua yam hnav refractory.

Porosity: Tswj porosity feem ntau yuav tsum tau tso cai rau cov cua txias gases thiab tiv thaiv kom tsis txhob kub dhau mus rau lub plhaub ntawm lub cub tawg.
