Corundum castable for circulating fluidized bed boiler returner in power industry

The corundum self-flowing wear-resistant refractory castable is composed of corundum, special grade high aluminum clinker and silicon carbide, and is composed of composite binder, water reducer and dispersant. The product has high wear resistance and erosion resistance. , resistant to erosion. The construction has extremely strong self-flow through its own potential, and the construction is extremely convenient. It is often used in CFB boilers and other thermal equipment to wash out parts that are severely worn and difficult to construct.

High-strength castables are made of corundum or high-quality high-alumina bauxite clinker, silicon carbide, etc., and are prepared by introducing various micro-powder, ultra-fine powder, corundum powder and admixture. In addition to the conventional high temperature wear resistance, the product has a certain amount of heat-resistant stainless steel fiber added to its ingredients, which prevents the rise of aggregate and matrix in the material at high temperature, and starts and stops the furnace. The stress generated by the change of the temperature gradient causes the furnace wall to be destroyed. At the same time, due to the addition of the steel fiber, the overall strength of the furnace wall after the material is poured is greatly enhanced.

[performance characteristics]

Good thermal shock resistance, flaking resistance, abrasion resistance, and resistance to acid medium.

[Scope of application]

Applicable to the high abrasion resistance, erosion resistance and tortoise shell of the refinery catalytic cracking equipment, cyclone separator and inclined tube device.

Processing equipment such as synthetic ammonia, one-stage, two-stage reformer lining pouring

Uses: Mainly used in the parts of the circulating fluidized bed boiler combustion chamber, separator and flue, which are easy to wash and wear.

Its main features are: high strength, wear resistance, erosion resistance, thermal shock stability and so on. Mainly used for circulating fluidized bed boiler lining and severe wear parts.

The high-strength and high-aluminum castable is made of special high-alumina clinker as the main material, plus composite binder and binder. The product has the characteristics of high strength, abrasion resistance, penetration resistance, erosion resistance, good mechanical properties and convenient construction. Commonly used in CFB boiler top, tail furnace wall and other parts.

Main features: high strength, high temperature, good wear and corrosion resistance. The products are divided into dense high-strength refractory castables, low-cement refractory castables, cement-free refractory castables and corundum refractory castables, which can be poured, inverted or sprayed. Mainly used for special high temperature equipment and the introduction of high temperature devices.

Product Description of Steel Fiber Reinforced Refractory Castable: Steel fiber reinforced refractory castable is made of high alumina clinker or corundum as aggregate and powder, adding binder and proper amount of heat resistant, stainless steel fiber and admixture. Hard refractory castable. Product performance of steel fiber reinforced refractory castable: steel fiber reinforced refractory castable has high strength, high temperature resistance, impact resistance, thermal shock resistance and good wear resistance. The steel fiber reinforced refractory castable product is divided into two types: ordinary stainless steel steel fiber reinforced refractory castable and nickel-plated stainless steel steel fiber reinforced refractory castable. Among them, nickel-plated stainless steel steel fiber reinforced refractory castable technology has better high temperature resistance and tamper resistance. Application of steel fiber reinforced refractory castables: Steel fiber reinforced refractory castables are mainly used in high temperature and vulnerable parts of metallurgy, building materials and circulating fluidized bed boilers. The above is the application and function introduction of steel fiber in castables. If you don't understand anything, you can contact us directly.
