Refractories Co., Ltd., Zhengzhou City shangzhuang understand some materials, such as silica-alumina refractory products, it is generally believed that at a certain temperature (eg within 700 ~ 900 ℃ less elastic range), the higher the temperature wear (Wear resistance) the lower the temperature increase can be considered as the rear when the elastic modulus of the refractory material price increases, abrasion resistance (Wear resistance) decreased. When the temperature increases the refractory wholesale, reaches a maximum elastic modulus, with the decrease of the elastic modulus, abrasion resistance (Wear resistance) but improved. Aluminosilicate refractory products such as during 1200 ~ 1350 ℃, abrasion or even better than those at room temperature. When the temperature is further increased, reaching more than 1400 ℃, the result of refractory products in liquid viscosity drastically reduced wear (Wear resistance) decreases. Some of refractory products, such as chromium-containing refractories Which is good quality, with increasing temperature, abrasion resistance (Wear resistance) increases. Refractories Co., Ltd., Zhengzhou City shangzhuang discovered over time, there are a lot of development refractories. The late 1950s, China's steelmaking and continuous casting has begun to enter the industrial production stage. Tundish lined with refractory or alumina bricks using clay brick masonry, because of the continuous casting production has just started, the continuous casting of steel more than ordinary steel, tundish just as molten steel container turnover, tundish lining working conditions not too bad, the service life of 5 to 12 continuous casting furnace, continuous casting production to meet the needs of the time. After tundish working lining brick, our country and the development of a castable pouring tundish working lining. Using castable casting tundish working lining, good overall performance, high mechanical strength; for partial severely damaged parts can be repaired, therefore, long service life.
