Cov hauv qab no yuav tsum tau muab tso rau pem hauv ntej rau lub cub tawg phab ntsa hauv cov ntaub ntawv refractory:

1. Txaus refractoriness

Nws refractoriness yuav tsum yog 1650 ~ 1780 ℃, thiab nws softening kub yuav tsum siab tshaj 1650 ℃.

2. Zoo thermal stability

Qhov kub ntawm lub cub tawg hauv ob sab phlu yog ib txwm hloov tas li, thiab cov phab ntsa ntawm lub cub tawg feem ntau tawg vim cua sov tsis sib xws, uas txo cov kev pab cuam lub neej ntawm lub cub tawg hauv ob sab phlu. Yog li ntawd, raws li ib tug refractory rau hluav taws xob furnaces, nws yuav tsum muaj zoo heev thermal stability.

3. Tshuaj lom neeg zoo

Cov tshuaj lom neeg ruaj khov ntawm cov khoom siv zoo sib xws rau lub neej ntawm lub tshuab hluav taws xob phab ntsa hauv ob sab phlu. Cov khoom siv hauv ob sab phlu ntawm lub qhov cub yuav tsum tsis txhob hydrolyzed thiab sib txawv ntawm qhov kub thiab txias, thiab yuav tsum tsis txhob yooj yim decomposed thiab txo qhov kub thiab txias. Nws yuav tsum tsis txhob yooj yim los tsim cov tshuaj uas tsis tshua muaj melting nrog slag thaum lub sij hawm smelting txheej txheem, thiab nws yuav tsum tsis txhob chemically react nrog hlau tov thiab additives, thiab yuav tsis pollute hlau daws. .

4. Me thermal expansion coefficient

Lub ntim yuav tsum ruaj khov nrog kev hloov pauv kub, tsis muaj kev nthuav dav thiab kev cog lus.

5. Muaj cov khoom siv tshuab siab

Nws yuav tsum muaj peev xwm tiv taus qhov paug tawm ntawm tus nqi hauv lub xeev qhov kub thiab txias; Thaum cov hlau nyob rau hauv lub kub kub molten lub xeev, nws yuav tsum muaj peev xwm tiv taus qhov zoo li qub siab ntawm molten hlau thiab muaj zog electromagnetic stirring nyhuv; hnav tsis kam thiab corrosion kuj nyob rau hauv lub sij hawm ntev yaig ntawm cov hlau molten.

6. Kev rwb thaiv tsev zoo

Cov phab ntsa ntawm lub qhov cub yuav tsum tsis txhob ua hluav taws xob ntawm qhov kub thiab txias, txwv tsis pub nws yuav ua rau cov dej xau thiab lub sijhawm luv luv, ua rau muaj xwm txheej loj.

7. Kev tsim kho ntawm cov khoom siv tau zoo, kho tau yooj yim, uas yog, kev ua haujlwm sintering zoo dua, thiab lub tshuab hluav taws xob thiab kev saib xyuas yooj yim.

8. Muaj peev txheej thiab tus nqi qis.
