Tam sim no, ferrosilicon nitride yog siv cov khoom siv refractory xws li casting cov ntaub ntawv, phom nyom thiab cov khoom siv phom tua.
1. Cov ntaub ntawv ua pov thawj: kev siv ferrosilicon nitride nyob rau hauv cov ntaub ntawv cam khwb cia, magnesia casting cov ntaub ntawv thiab siab aluminium casting cov ntaub ntawv.
2. Phom Slurry: Rab phom slurry yog ib qho tseem ceeb refractory siv los thaiv lub moj tej tawg sov sov. Thaum lub sij hawm borehole, slag thiab hlau tawm ntawm lub duav los ntawm tib lub sijhawm. Raws li cov hluav taws kub ua kom zoo txhim kho thiab kev pabcuam lub neej nce, thiab kev tawm tsam ntawm cov tshuaj tshiab smelting, thiab muaj peev xwm zoo dua tuaj yeem tiv taus tshuaj, slag thiab hlau eragion. Ib qho ntxiv, nws yuav tsum muaj peev xwm tiv thaiv tau qhov kub thiab txias, yoojyim rau sau, thiab ruaj khov nyob rau ntawm qhov kub. Ib qho ntxiv, nws yuav tsum yooj yim qhib thiab kaw, zoo li tiv thaiv lub hear.
Thaum siv, cov hlau ntws hauv cannon kev daws muaj cov nitride nyob ruaj khov, dawb ntawm anomalous ci thiab liab me ntsis. Nws muaj lub zog flexural siab ntawm cov kub thiab kev tawm tsam rau cov hlau molten hlau. Nws tuaj yeem ua tiav cov kav hlau ruaj khov rau ntau tshaj 60 feeb thiab thaiv cov hlau kom tiav. Qhov ncauj, tsis muaj qhov tshwm sim ntawm cua thiab hluav taws. Composite cov ntaub ntawv refractory los ntawm ob lossis ntau dua refractory raw cov ntaub ntawv nrog cov khoom sib txawv. Lawv muab cov khoom siv tshiab tsim cov khoom tshiab ntawm ib qho macro (micro) uas siv lub cev lossis tshuaj lom neeg.
