What are the application ranges of steel fiber castables?

Nov 13,2021

Steel fiber castable is made of special grade bauxite clinker as aggregate, high-quality bauxite clinker and fine corundum powder as matrix, superfine powder and other composite materials as binders and additives, and stainless steel heat-resistant fiber. become. At the same time, due to the addition of steel fibers, the overall strength of the furnace wall is greatly enhanced after the material is poured. It has the characteristics of high strength, high temperature resistance, impact resistance, thermal shock resistance, and good wear resistance. In fact, the scope of application of steel fiber castables is very wide.

The scope of application of steel fiber castables:

1. Industrial boiler lining, the effect is more obvious when used on the top of the furnace;

2. The flue, heat insulation in the large-diameter metal chimney;

3. Use flat-flame industrial furnaces, the roof of the furnace is sealed and insulated, and the sealing effect is better than any other materials;

4. Low temperature air (≤1200℃) pipe insulation;

5. Inner lining of various thermal equipment;

6. There is no mechanical vibration in the task, and the furnace lining with large temperature changes is particularly suitable, such as bell furnaces, removable aluminum melting furnaces, etc.;

7. Resistance furnace lining with task temperature ≤1200℃, the electric heating element can be exposed, and it can also be made into an embedded structure;

8. The anti-carburizing fiber castable is used for the lining of the muffle-free carburizing furnace;

9. All kinds of fuel furnace linings with working temperature ≤ 1250℃, including furnace wall and roof. Different types of refractory fiber castables are used to make composite furnace linings, with fluctuating structure, economical and reasonable, and convenient construction;

10. Ultra-low temperature type refractory fiber castables, polycrystalline mullite fiber castables, alumina fiber castables, which can be used for industrial furnace linings with working temperature of 1300-1450℃;

11. Various general and special-shaped prefabs can meet the special application requirements of users;

12. Backing insulation layer (including furnace wall and roof) with a variety of low-temperature furnace interface temperature ≤1050℃;
