Factory price lightweight silica refractory brick for glass kiln

LONGKETER supplying a comprehensive range of Light Weight Silicate Bricks. Light Weight Silicate Bricks are made from high-purity refractory clays ;temperature of use ranging from 1100℃ to 1700℃ and each grade is formulated to meet specific thermal and physical requirements . For higher temperature products , their addition of alumina are graduated .Each grade is added by classified organic filler . This organic filler burns out during manufacture process to give a uniform and controlled pore structure .

Light Weight Silicate Brick also known as silicon insulation brick. Light refractories with silica content over 91% and bulk density below 1.2g/cm3. The refractoriness and load softening temperature are similar to those of common silica brick. However, due to many pores, the compressive strength, slag resistance and corrosion resistance are not as good as those of ordinary silica brick, while the thermal shock resistance is improved.

Using fine silica as raw material, the critical particle size is usually not more than 1mm, and the particle size less than 0.5mm is not less than 90%. A porous structure is formed by adding inflammable substances into the ingredients or gas generation method, and is made by firing. It can also be made into unburned products. It is mainly used in various parts of the kiln which require heat insulation or reduce the self weight without direct contact with the melt, without the action of aggressive gas and without the rapid change of temperature. When used at high temperature, it shall not contact with basic refractories. According to different materials, the maximum operating temperature is 1200-1550 ℃.
