Product Overview
Description
Specification
High Alumina Castable Refractory
High alumina castable refractory is monolithic refractory materials, which is made of high alumina aggregateand powder, binder and water reducer, Among them, the Al2O3 content is between 50% and 80%.The high alumina castable properties are mainly high mechanical strength,good heat and shock resistance, anti-abrasion and so on. Due to its good performance, refractory high alumina castable is widely used in steel industry, petroleum industry, chemical industry, and other industries. It can be used on the linings of all kinds of furnaces and kilns, such as boiler, blast furnace, hot stove, heating furnace and ceramic kiln.
Character
The prominent character of low cement castable is high and strong densification which brings benefits of its using:The CaO in it is lower, which reduces the produce of eutectic phase in material and develop its refractoriness, high temperature strength and slag erosion resistance.The water used for the blending of castable during construction is only 1/3~1/2 of water for normal use, which realizes low apparent porosity and high bulk & density.After moulding by casting, the cement compound produced during maintenance is less. There is no damage of large amount of hydrated bond during heating and roasting, which will reduce the medium temperature strength. But for low cement castable, the strength is increasing with the increase of heating temperature.Adjusting the size composition of castable can compound self-flow castable and pump irrigation castable.
Application
Low cement castable is used in the back kilneye, wicket cover and back of cooling machine of cement rotary kiln and other thermal equipment with good performance and long service life.
