Low-cement castables/Used for industrial furnaces/Has a good flow ability, easy installation, good anti-spalling
Product description:
 Using high quality bauxite and mullite as the main materials, the ultrafine powder bonded low cement castables for furnace lining are characterized with good flow ability, easy installation, good anti-spalling and thermal shock resistance, low thermal expansion, and good thermal insulation. The products can be widely used at roof, wall and bottom for industrial furnaces.
Low-cement castables
This new generation of products is developed with high quality mullite and bauxite as the main raw material by adding proper corundum, compound ultra-fine powders and efficient dispersion additives, and characterized with good performance at high temperature as well as high strength, low porosity and low thermal insulation.
Category of Refractory Castable:
Features:
These castables can be put into use after short curing and firing period,and can be applied to furnace with tight construction schedule,and the parts being difficultly fired.
