How to evaluate the density of refractory brick

With the continuous development of China’s cement industry; higher requirements for fire resistant materials are also put forward. Long term dependence on the extensive economic growth mode of the refractory industry, should be increased to adjust the intensity of the need to adapt to the new situation, then in the purchase, we should be how to determine the density of fire bricks, and hope that the following text will help.

Refractory brick is a rich in hydrous aluminum silicate siliceous clay and has the capability of high temperature deformation, not broken, do not soften and not paste, refractory bricks in the amorphous material department, there are a variety of consumer products, the basic quality requirements of alumina is higher than 38% and low iron and low content of alkali metal. These products can be claimed or calcined, such as refractory clay, overloaded with plastic material, high alumina plastics, fireclay and high alumina pouring material and the other. Different quality mud with different appliances, cement with clean water, accurate weighing modulation, uniform mixing.

If is already a good tune mud, it shall not be arbitrarily diluted with water and mortar plumpness to greater than 95% above to ensure dense refractory brickjoints, surface brick joints to puree pointing, housing cannot correct position with mud is looking. Bricks with a certain shape and size, weight per unit volume, density, that good compactness and strength is likely to be, also called high temperature load to deformation temperature, called heavy firing line changes or called residual line change, refers to each in the same temperature changes in volume expansion and contraction of the change, high temperature resistant, about 1800 degrees, refractoriness under load in 1620-1640, low coefficient of thermal expansion.
