The high-strength wear-resistant self-flowing castables are made of high-quality bauxite clinker, mullite and fused corundum. The pure calcium aluminate cement, corundum micro-powder and silicon micro-powder are used as binders.
The high-strength wear-resistant self-flowing castables are made of high-quality bauxite clinker, mullite and fused corundum. The pure calcium aluminate cement, corundum micro-powder and silicon micro-powder are used as binders. Such self-flowing castable has the characteristics of high strength, good thermal shock resistance, abrasion resistance, erosion resistance and strong corrosion resistance.Self-flowing castable has good fluidity and convenient construction. Self-flowing refractory castable can be used in CFB boilers and other high temperature furnaces.
Applications of Self-flowing Castable:
The self-flow castable has widely application, especially for blast furnace iron runner, department between stave cooler and blast furnace shell.
Advantages of Self-flowing Castable:
• Environment friendly
• No need vibration and easy to construct to save labor time
• Reasonable raw material and size to make sure good fluidity
• High strength and high refractoriness
