1, Khoom piav qhia:
Cov ntaub ntawv tseem ceeb ntawm cov khoom yog zoo fused magnesia, fused corundum xuab zeb thiab sintered mullite xuab zeb. Cov khoom tsim corundum theem, spinel theem thiab mullite theem cov khoom siv hauv cov txheej txheem ntawm kev siv. Nws muaj cov qauv compact, zoo spalling kuj, zoo heev cuam tshuam tsis kam thiab yaig kuj.
Cov khoom siv raw muaj siab purity, tsis muaj kuab paug rau molten steel, zoo mechanical zog ntawm kub thiab zoo ntim stability ntawm kub. Tshwj xeeb tshaj yog thaum lub sij hawm ua hauj lwm ntawm lub ladle, cov khoom muaj zoo heev los tiv thaiv stripping kev ua tau zoo, uas nyob ntawm cov nyhuv ntawm corundum theem thiab spinel theem khoom tsim nyob rau hauv high kub. Daim ntawv thov cov nyhuv ntawm cov khoom yog zoo dua li ntawm lwm yam refractory castables.

4, Daim ntawv thov ntawm Castable rau Phab ntsa Ladle:
1) Loj ladle
2) Nruab nrab ladle
3) Tundish rau Nruam Casting
5, Khoom paub:
1) Cov hmoov zoo spinel hauv cov khoom tuaj yeem nqus tau ntau cov hlau oxide hauv cov slag, ua kom cov hlau oxide khov thiab ua kom qeeb ntawm cov slag.
2) CaO hauv slag thiab Al2O3 hauv cov hmoov zoo ntawm cov khoom tsim cov khoom zoo li rab koob, uas ua rau cov pore zoo thiab inhibits slag nkag.
3) Cov kua theem ntawm SIO2 ua viscous thiab inhibits slag nkag.
6. Cov lus pom zoo ntawm cov khoom siv tau zoo, cov khoom tau raug xa tawm mus rau Australia, Oman, Kenya.
7.Peb yog cov kws tshaj lij kev lag luam, uas tuaj yeem muab cov neeg siv khoom siv khoom siv dawb, siv thiab lwm yam teeb meem.
