product introduction
High-alumina self-flowing castable has excellent fluidity and gap permeability. During the construction process, the material can automatically flow and fill various parts without additional vibration or compaction. The surface is smooth and flat after demolding.
Product application:
High-alumina self-flowing castables are widely used in thermal equipment with thin linings, difficult to construct or repair linings, etc. Self-flowing refractory castables are often used in those thermal equipments such as ladle, tundish, blast furnace iron runner and runner making, boiler tube protective layer and incinerator grate, heating furnace and cement kiln.
Welcome to contact us for our high alumina self-flowing castables and any information you want to know.
