Develop the fundamental way that fireproof material produces roof

   Develop roofFireproof materialFundamental direction of production is to should increase square magnesian Shi Jianjing the crop that the high density with stone brick and firing high temperature spends magnesian chromium brick, with be being protected adequatelyThe need of card black metallurgical industry. In the meantime, improve the composition of open-hearth furnace roof. Fireproof material still can use pointed spar of square magnesian stone goodly at coloured metallurgyFurnace, the rotary kiln of to calcine cement. The high density magnesia brick that if produce build by laying bricks or stones to build mouth of open-hearth furnace tapping and the broken bits that make the same score post of the fence before furnace,takes an all sorts of needed measure and with liner of spray of special type pug, the use effect of roof of magnesian chromic brick will be better.
