Product Description
Description of Light Weight Refractory Concrete Castable for Lining of Furnace
The Description:
Generally, castables with a bulk density of < 1.8g/cm³, but no requirements for refractoriness, or true porosity > 45% and linear shrinkage < 1.5% at a specified temperature are called lightweight castables.
The Feature and Light Weight Refractory Concrete Castable for Lining of Furnace
Lightweight castable is made of aluminate cement, high aluminum fine material, ceramic particle, plus some additives. The product has light volume, high compressive strength, acid and acid gas corrosion resistance. The characteristics of heat insulation, heat preservation, low water absorption, simple construction, is the most ideal product for alkali corrosion resistance at high temperature. Good workability, strong adhesion, long initial setting time and construction operable time, fast strength growth, strong permeability resistance, no need for acidification treatment, easy to ensure the dense and full masonry ash joint, can significantly improve the air tightness and integrity of the chimney lining wall and the anti-corrosion ability of the lining, is an ideal cementation material for the lining of high chimney, high temperature flue and air duct. Can also be used in petroleum, chemical, non-ferrous metallurgy and other industries of acid-proof tank, tank and other acid-proof engineering. Acid-resistant brick, acid-resistant mortar and coating fabric are the special refractory materials developed by our factory, which are suitable for the insulation of power station boiler chimneys and heat network pipes. It has the characteristics of acid corrosion resistance, temperature resistance, heat stability and convenient construction.

The Feature:
1, The refractoriness is similar to the refractory brick of the same material, but because the refractory concrete (castable) is not sintered, the shrinkage is larger when the initial heating, so the load softening point is slightly lower than that of the refractory brick. Nevertheless, on the whole, the performance is better than that of refractory bricks.
2, Refractory concrete is better than the role of low temperature binder, high compressive strength at room temperature. At the same time, because the integrity of the masonry is good, the air tightness of the furnace is good, and the deformation is not easy, the steel plate of the outside furnace shell can be cancelled, and the performance of the furnace against mechanical shock and impact is better than that of the brick masonry. For example, the side wall of the soaking furnace is used, where the mechanical wear and collision are more severe, and the life is several times higher than that of the brick.
3, Good thermal stability, most or all of the aggregate is clinker, expansion and contraction of cement offset, so the thermal expansion of masonry is relatively small than brick, temperature stress is also small, and there are various mesh, needle, chain crystalline phases in the structure. Strong resistance to low temperature stress. For example, it is used to pour the pit furnace mouth and the furnace cover, and the life is extended to one and a half years.
4, The production process is simple, cancelling the complex brick making process. It can be made of a variety of prefabricated blocks, and can be mechanized construction, greatly speeding up the furnace building speed, and more than ten times more efficient than bricklaying. Waste bricks can also be used as aggregate to turn waste into profit.
