Product Description

Unshaped Andalusite Refractory Brick for Coke Oven
The Description:

Coke oven is a kind of thermal equipment with complex structure and continuous production. The main parts of refractory materials include combustion chamber, carbonization chamber, furnace top, ramp, regenerator chamber and small flue. Different parts of the furnace body withstand the temperature, load and the degree of corrosion of the medium are different, so different refractory materials are used, generally Al2O3-SiO2 refractory products. The A12O3-SiO2 series refractory materials used in Chinese coke ovens are easy to shrink, crack and flake during high temperature and cooling process, especially in the special parts of the coke oven temperature environment, the use and life of this material are limited. Andalusite has excellent corrosion resistance, high load soft, creep resistance, thermal shock resistance and other properties, making it has a unique application in coke ovens, this refractory material in metallurgy, building materials, electric power, chemical industry and other industrial fields of kiln and boiler have great space for use, with broad prospects for development.

The characteristics of andalusite are obvious:
Low mullite temperature; The thermal expansion in the conversion process is low. The coarse crystal can be used as aggregate, all of which allows andalusite to be directly used in the manufacture of fired or non-fired refractory bricks without calcination, and saves a lot of energy. Andalusite refractory brick has a series of points, it has strong creep resistance, creep is a measure of refractory brick long-term resistance to high temperature load, can lead to premature softening of refractory brick melt impurities on the impact of creep is huge, even high quality dense clay brick will have about 5% Fe2O3, TiO2, R2O and so on. The number of melt impurities contained in andalusite refractory bricks is small, so the creep value of 25 hours under the condition of 1300ºC/0.2MPa is 0.28%, which is only 20% to 25% of the clay brick containing 42%, which is lower than the high alumina brick containing Al2O385%. Another characteristic of andalusite refractory brick is its high strength at high temperature and small decrease with increasing temperature. The high temperature strength is related to the amount of liquid phase formed inside the refractory brick at high temperature. Besides. Andalusite firebricks also have the characteristics of good volume stability at high temperature, thermal shock stability in other Al2O3-sio2 refractory bricks with the same Al2O3 content, and strong resistance to chemical erosion
