Description:
Steel Fiber Reinforced Refractory Castable is produced by adding refractory steel fiber into the raw material to grant it a higher strength and thermal shock resistance, thus finally to increase its wear resistance capacity and service life. The castable is mainly used in high temperature wearable parts such as the kiln eye, feed opening, the wearable pier and the lining of the powder plant boiler.
Application:
1. Furnaces of metallurgy industry, heat treatment furnace.
2. Furnace of incineration of garbage, recirculating fluidized bed furnace.
3. Furnaces of chemical industry and construction industry.
Features:
1. High refractoriness, High refractoriness under load.
2. High density, low porosity.
3. Good slag resistance and corrosion resistance.
4. High strength and wear resistance.
