Supply Low Price Furnace Liner Refractory Silica Ramming Mass For Construction Of Various Kilns Lining
Silica ramming mass is made of quartz (SiO2) refractory raw material as aggregate and a certain proportion of powder, binders and additives, which can be used?for construction of lining of various kilns. The silicon ramming mass introduced today is used in the working layer of the tundish, and the service life can be up to 30 hours after the overall casting, which is generally applicable to small and medium-sized tundish.

Product Features of Silica Ramming Mass For Various Kilns Lining
1. Convenient construction, mechanized operation and improved working efficiency
2. Compact sintering, erosion resistance, and long service life
3. Do not pollute the molten steel, and meet the needs of clean steel continuous casting
4. The working layer does not crack during use, and it is easy to turn over the package

Advantages of Silica Ramming Mass

1. Convenient construction and time saving
2. Quick baking can improve the operating rate of furnace lining
3. The constructed lining is easy to be repaired when the lining is removed

Applications of Rongsheng Refractory Ramming Mass
Ramming Mass mainly used for furnace lining of boiler, blast furnace, hot blast stove, heating furnace, ceramic kiln and various industrial furnaces.Applicable to all kinds of carbon steel, low manganese steel, alloy steel, alloy cast iron, high-speed tool steel and stainless steel.
