Cov Cib Magnesia Chrome Uas Ua Tau Zoo Rau Cov Cement Thiab Metallurgy Rauv Refractory

Magnesia chrome cib yog cov khoom siv alkaline refractory zoo tshaj plaws uas ntseeg tau rau cov xwm txheej kub thiab tshuaj lom neeg ua haujlwm hnyav. Ua los ntawm cov khoom siv raw magnesia thiab chromite uas muaj cov khoom siv siab, lub cib tsim cov periclase thiab magnesia-chrome spinel microstructures ruaj khov, muab lub zog kub thiab tiv taus slag zoo heev. Nws ua haujlwm ua cov tshuaj txhim khu kev qha rau kev tsim cov cement, kev ua kom hlau, thiab kev lag luam metallurgy uas tsis yog ferrous thoob ntiaj teb.

Qhov zoo tshaj plaws ntawm cov cib magnesia chrome yog lawv qhov kev tiv thaiv xeb ob npaug. Tsis zoo li cov cib refractory ib txwm uas tsuas yog hloov kho rau ib qho kev ua haujlwm xwb, peb cov cib magnesia chrome ua haujlwm ruaj khov tiv thaiv ob qho tib si alkaline cement clinker erosion thiab acidic smelting slags. Cov qauv sab hauv ntom ntom thiab sib xws zoo tiv thaiv cov khoom molten nkag mus, txo cov ntaub hauv qab hnav thaum ua haujlwm kub ntev. Qhov no feature ntev lub neej ua haujlwm ntawm lub cub tawg thiab txo cov nqi kho ntau zaus rau cov lag luam kev lag luam.

Cov cib no muaj kev ruaj khov zoo heev rau kev kub thiab txias sai sai yam tsis muaj tev tawm lossis tawg. Lawv tswj tau qhov ruaj khov ntawm cov qauv hauv qab qhov kub thiab txias hloov pauv, uas yog qhov tseem ceeb rau kev tsim cov cement rotary kilns thiab cov cub tawg smelting. Muaj qhov refractoriness siab dua 2000 ° C thiab kev ua haujlwm ruaj khov ntawm kev ua kom mos, cov cib no txhawb nqa kev ua haujlwm ntev ntawm 1600 ° C txog 1800 ° C, hloov kho zoo rau qhov chaw kub thiab txias hauv kev lag luam.

Cov cib magnesia chrome siv dav hauv cov cheeb tsam tseem ceeb uas muaj kev hnav ntau, suav nrog cov chaw hlawv cement rotary kiln thiab cov cheeb tsam hloov pauv, AOD furnaces, ladle refining furnaces, thiab tooj liab, nickel thiab lwm yam khoom siv smelting hlau uas tsis yog ferrous. Nrog cov khoom siv lub cev thiab tshuaj lom neeg ruaj khov, lub zog kho tshuab siab thiab porosity qis, peb cov khoom ua kom lub cub tawg ua haujlwm tas li thiab txhim kho kev ua haujlwm ntau lawm.

Peb muab cov cib magnesia chrome uas zoo thiab zoo tshaj plaws nrog kev tswj xyuas zoo. Txhua pawg tau dhau los ntawm kev kuaj lub cev thiab tshuaj lom neeg kom ntseeg tau tias ua haujlwm tau zoo hauv cov xwm txheej ua haujlwm hnyav. Rau cov khoom siv refractory uas ruaj khov thiab pheej yig rau koj lub cub tawg kev lag luam, peb cov cib magnesia chrome yog koj qhov kev xaiv zoo tshaj plaws.
