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, choose a good raw material, although the price a little high, but the quality is guaranteed. With the development of refractory industry Which is good, 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 refractory brick manufacturers qualitative interaction, as well as the strength of refractories, resilient touch cricket, thermal conductivity, thermal expansion coefficient, specific heat density drive and so on. 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 refractories, refractory materials for low expansion is very effective.
