Shangzhuang Refractories Co., Ltd., Zhengzhou City, learned basic refractories main varieties: magnesia-chrome brick, brick, brick spinel, dolomite bricks. Magnesia-chrome brick is divided into ordinary magnesia-chrome brick, magnesite-chrome brick combined direct, semi-direct combination of magnesia-chrome brick. Basic refractories primarily used in cement kilns burning zone, transition zone and kiln site. In particular refractory offer, spinel brick lining material has become one of the major large-scale cement kiln kiln, its use in the transition zone, and gradually the use of the cooling zone, kilns, even for the firing zone. Basic refractories, refractory thermal shock resistance are poor, only a few times. When in use, the key is to be able to hang kiln skin. Just keep proper kiln thick skin (200 ~ 300mm), will be able to compensate for the lack of basic refractories poor thermal shock resistance. Spinel brick To promote the use of the firing zone, should also solve the problem of skin hanging kiln. 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 material, 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 the large refractory manufacturers, internal stress generated by the temperature change can cause cracks in the material of the refractory lowest, most cases product damage phenomenon. This solid, to improve the thermal shock resistance of refractories, refractory materials for low expansion is a very effective method.
