Refractories Co., Ltd., Zhengzhou City shangzhuang find 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 refractory Which is good, good choice of materials, although the price a little high, but the quality is guaranteed. With the development of industry, excellent thermal shock resistance and high temperature refractory more and more urgent. Refractory thermal shock resistance generally depends on the size and shape of the refractories, heating and cooling boat quality of interaction, as well as the strength of refractories, resilient touch cricket, thermal conductivity, thermal expansion coefficient, specific heat driving density. In the above-mentioned factors, the most important is the thermal expansion coefficient of the refractory bang. If the thermal expansion coefficient of the material of the large, internal stress caused by temperature changes can cause cracks in the material, the majority of occasions products damage phenomenon. This solid, to improve the thermal shock resistance of the refractory plastic refractories manufacturers, choose low-expansion refractory material is a very effective method. Shangzhuang Refractories Co., Ltd., Zhengzhou City, specializing in the production of refractories, welcome everyone to buy.
