High Strength Refractory Castable Details
High strength refractory castable has a compact organization structure, strong thermal volume stability, strong corrosion resistance and wear resistance, high compressive and flexural strength, good thermal shock resistance and low resistance to mechanical peeling.
It is minimizing alumina cement for using various dispersants and ultra fine powder so it has excellent abrasion resistance, erosion resistance, spalling resistance and chemical resistance . It widely used in part of various industrial furnace including incinerator, nonferrous metal furnace etc.
The structure of particularly dense, high strength refractory castable containing only a small amount of moisture, are formed, using special binder, following the theory of dispersion, peptization and coagulation of closely composed high strength castables.
High strength refractory castable can usually be mixed with water at the construction site. Its construction and mixing quality is very good. After manual plastering on the surface of the silo or mine trough, it can form a wear-resistant layer of a certain thickness, which can reach the skill requirements after routine protection. It has the characteristics of high wear resistance, high bond strength to the base concrete, strong impact resistance, high pressure resistance, good durability and long service life.
Features
1. High strength, high abrasion resistance, impact resistance, erosion resistance, oil penetration resistance
2. Good flame retardancy, low water absorption, high and low temperature resistance
3. Good durability and long service life
4. Simple construction, fast operation and easy to master
5. Good integrity, easy to repair, not easy to fall off
6. Non-toxic, odorless, green and environmental protection, no physical damage to the operator
Applications
1. Coal unloading ditch, coal hopper, coal storage bin, dry coal fence, dumper, slag catcher, water treatment, etc. in the power generation industry.
2. Anti-corrosion ground and pump foundation for chemical industry.
3. Wear-resistant linings in coal gangue bunkers, media drums, scrapers, bucket elevators, chutes, sieve hoppers, etc.
4. Blast furnace mixing silo, sintering silo, feeder, ball making machine, etc. in the steel industry

Semi-silica brick refers to an aluminum-silicon refractory product with a SiO2 content of greater than 65% and an Al2O3 content of 15% to 30%. They generally use clay containing quartz impurities or native kaolin refractory clay or tailings and pyroph...
The Al2O3 content of anchor bricks is above 55%, and some users require that the alumina content reach 75%, and the load softening temperature of 75% bricks reaches 1550C. However, in actual use, anchor bricks with high aluminum content cannot be enough. The key is Flexibility is the most important t...
