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, can be considered when the temperature was increased with the increase after the elastic modulus, abrasion resistance (Wear resistance) decreased. When the temperature rises, reaches a maximum elastic modulus after, 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 ℃ when customizing alumina magnesia carbon brick, refractory products due to the viscosity of the liquid alumina magnesia carbon brick custom drastically reduced, wear (Wear resistance) decreases. Some of refractory products, such as chromium quality custom alumina magnesia carbon brick, with increasing temperature, wear (Wear resistance) increases. Refractories Co., Ltd., Zhengzhou City shangzhuang understand the production process according to the extent and shape dense products different sintering method, casting method and melt blowing method. Sintering is part of the pre-firing clinker raw material, crushing and screening custom alumina magnesia carbon brick, then mixed with a certain proportion of the raw material, after forming, drying and firing. The purpose of the pre-burning material which is moisture, organic impurities, sulfate decomposition of gas burning to reduce the firing shrinkage of products, to ensure the accuracy of product dimensions. After crushing and grinding of raw materials also need to go through screening, because the powder material consisting of different size were graded, you can ensure that the most closely packed to obtain dense bodies. [Custom] alumina magnesia carbon brick, alumina magnesia carbon brick custom, yet still provided by the Zhuang Zhuang Refractories Refractories.
