Steel fiber refractory castable material refers to a certain size of heat-resistant steel fiber added to refractory aggregate, binder and admixture composition of castable refractory. It is a kind of refractory used in fluidized bed boiler.
This series of refractory castable advantage, good quality, is worthy of customer trust one of the best selling products.
The furnace lining of steel fiber refractory castable has no seam and the fiber is arranged in three-dimensional direction. Under high temperature use, the furnace lining does not produce directional shrinkage and no cracks. The integrity of the furnace lining is good, the air tightness is good, the insulation effect is good, and the service life is long. The construction technology is simple, the speed is fast, the material consumption is small. The requirement on the position of anchor nails in the special shape of furnace lining is not strict, so that the design is simplified and the construction is easy.
Moreover, the refractory castable has better mechanical properties, certain strength, bearing capacity and strong resistance to airflow erosion. It also has a strong adaptability to the atmosphere in the furnace, and can be used for various fuel furnaces. In the reducing atmosphere, the lining can be used for a long time to strengthen the toughness, improve the stress and strain resistance, and improve the mechanical impact.
Steel fiber refractory castable with good thermal shock resistance, anti-spalling and anti- cracking, simple operation, only the selected formula and raw materials through mixing processing evenly, and then with the vibrator compaction after curing and heating treatment can be used. The overall strength of the furnace wall is greatly enhanced after pouring. In CFB boiler, it is often used for the furnace outlet, side wall, top, straight section of cyclone separator, top of cyclone separator, feeder and other parts.
