The special design of the silica ramming mass allows it to form an extremely strong glaze on the hot surface at a lower temperature. At the same time, it has a good loose backing in extremely high temperatures. Moreover, the high performance silicon ramming mass produced by Kerui has excellent corrosion resistance for high alloys.
The silica ramming mass composition is silica. Silica is the general name for vein quartz, quartzite and quartz sandstone. We mainly use silica to make acid refractory bricks for the metallurgical industry, such as fused silica refractory. Moreover, siliceous ramming materials are bulk materials made of silicon carbide, graphite and electrically calcined anthracite as raw materials, mixed with a variety of ultrafine powder additives and electrofused cement or composite resin as binding agents. It is used to fill the gap between the furnace cooling equipment and the masonry or the filling material for the masonry leveling layer.
Aggregate and powder account for a large proportion of siliceous refractory ramming materials. However, the proportion of binders and other components is very low and some are even entirely composed of aggregates and powders. Because refractory ramming materials are mainly used in direct contact with molten materials. Moreover, Kerui siliceous ramming materials have good chemical stability, strong erosion resistance, strong wear resistance, great peeling resistance and excellent thermal shock resistance. So, choosing Kerui’s ramming materials and flexible fire cement is equivalent to choosing a quality guarantee.

The production of siliceous ramming materials requires a reasonable silica sand particle size ratio and the addition of an anti-penetration agent, anti-cracking agent and anti-corrosion agent. Therefore, this makes the furnace lining volume relatively stable and eliminates the expansion and contraction of the furnace lining. In other words, all the heat energy emitted by the furnace does useful work, so the thermal efficiency is high.
Kerui siliceous ramming mass can withstand higher temperatures than ordinary furnace lining refractory ramming materials. Therefore, with it, the load softening temperature of the furnace lining can be increased when working at high temperatures. Besides, it can also slow down the sintering speed inside the furnace lining. So, siliceous ramming mass makes the service life of the furnace lining longer than that of ordinary furnaces.
Our ramming material turns the electrical energy of the furnace into active heat energy and performs useful work. Practice has proved that the melting speed is accelerated and one furnace can increase the output by more than 200KG per day. At the same time, this also extends the service life of the furnace and improves the metallurgical quality of smelting. This reduces metal burning loss, which is economical and affordable.
We mainly use siliceous ramming materials for the working lining of coreless induction furnaces for melting cast iron and cast steel, hot blast furnaces, coke ovens and glass furnaces. Moreover, you can also use it as a filler for gaps and screeds in high-temperature masonry. In addition, it is also the best charge for smelting bronze, red copper and white copper in power-frequency furnaces and medium-frequency furnaces. In mechanical equipment, you can also use silica ramming materials used as shock-absorbing pads. This can reduce vibration and shock when the equipment is running and protect equipment parts from damage.
