Refractory Silica Ramming Mass for Electric Furnace

Ramming material refers to the construction with ramming (manual or mechanical) method, and under the effect of higher than normal temperature of the heating sclerosis not stereotypes refractories.Ramming material with silicon carbide, graphite, electrically calcined anthracite as raw material, adding a variety of ultrafine powder additives, fused cement or composite resin as binder made of loose material for body.By a certain gradation of refractory aggregate, powder, binder and additive after mixing with water or other liquid.According to the material classification with high aluminum, clay, magnesite, dolomite, zircon and silicon carbide - carbon refractory ramming material.Used to populate the furnace body cooling equipment and masonry clearance or masonry leveling layer with a filling material.Ramming material good chemical stability, resistance to erosion and abrasion resistance, spalling resistance, thermal shock, widely used in metallurgy, building materials, non-ferrous metal smelting, chemical industry, machinery manufacturing industry.

Advantages of  the  Refractory mass

1. To improve the thermal efficiency of the stove
Due to the reasonable ratio of silica sand and impermeability agent, anti-cracking agent, corrosion inhibitor, etc., the furnace volume is stable, to eliminate the lining expansion and contraction; porosity is small and dense; in high temperature sintering and other physical and chemical action does not melt, Liquid impermeable; conductive thermal conductivity, the furnace issued by the heat, are doing useful work, high thermal efficiency.

2.To improve the furnace life
Due to the basic mineralization of silica sand, the lattice structure is stabilized and the crystal structure is controlled. Which is higher than the actual temperature of the lining material. To use this feature, the lining of the work at high temperatures, with it can improve the furnace refractoriness and load softening start temperature, you can also play to slow down the lining of the sintering speed. So lining life than the average furnace life longer.

3. To improve the daily output
It is precisely because the silica sand matrix to join a certain amount of admixture of mineralization, good insulation properties, high thermal efficiency, so that the furnace power into active energy, made a useful work. Practice has proved that the melting speed, a furnace can increase the maximum yield of 200KG a day, while the furnace life extension, smelting metallurgical quality has been improved, and reduce the metal burn, that is economical and affordable.
