Refractories Co., Ltd., Zhengzhou City shangzhuang learned carbon neutral refractories refractory products are another agent, according to the carbonaceous feedstock composition and mineral products, divided into carbon bricks, graphite products and silicon carbide products three class. Shangzhuang Refractories Co., Ltd., Zhengzhou City, specializing in the production of refractories quality and security, ensuring quality price, never let customers down. Shangzhuang Refractories Co., Ltd., Zhengzhou City, found a good raw material for the production of refractory materials is very important. Production of refractories, be sure to grasp the procurement of raw materials selection, choose a good raw material prices, although a little high, but the quality is guaranteed. With the development of industry, excellent thermal shock resistance and high temperature refractories have become increasingly urgent. Refractory thermal shock resistance generally depends on the size and shape of the refractory refractories, heating and cooling boat quality of interaction, and strength refractories, the elastic touch cricket, thermal conductivity, thermal expansion coefficient, specific heat driving density. In the most important of these factors is the thermal expansion coefficient of the refractory bang. If the thermal expansion coefficient of the material of refractory Which large, internal stress generated by the temperature change will cause cracks in the refractory inner material prices, most cases article destruction phenomenon. This solid, to improve the thermal shock resistance of refractories, refractory materials for low expansion is a very effective method.
