Silica Ramming Mass is one type of ramming mass and belong to monolithic refractory material for sale from Rongsheng Refractory Company in China. This kind ramming mass is mainly made of silica as the raw material and is mainly used for acid refractory bricks in metallurgical industry. If you have any questions or requirements, welcome to contact us for detailed information.
What is Silica Ramming Mass
Silica Ramming Mass is produced with silicon carbide, graphite and calcined anthracite as its raw materials, mixed various super fine powder admixtures and binding agents of fused cement or composite resin. And its main raw material is silica, the silica is the general term of vein quartz, quartzite and quartz sandstone.
Properties of Silica Ramming Mass
- Silica ramming mass has the appearance properties of appearance, cross section, color, gloss and inclusions of silica. By appearance, it can be preliminarily determined whether the silica is crystalline silica or cemented silica and whether it is vein quartz.
- Refractory silica ramming mass material has good properties of chemical stability, washing-out resistance, abrasion resistance, antistripping and thermal shock resistance.
Uses of Silica Ramming Mass
- Silica Ramming Mass refractory is mainly used for acid refractory bricks in metallurgical industry.
- It can be widely used in the chemical industry to prepare silicon compounds and silicates and also be used as a filler in sulfuric acid towers.
- It can be used for glass, ceramics and portland cement in the building materials industry.
- Silica ramming mass can be used to fill the gap between the furnace cooling equipment and the masonry or the leveling layer of the masonry.
- It is widely used in metallurgy, building materials, non-ferrous metal smelting, chemical industry, machinery and other manufacturing industries.
Compositions of Silica Ramming Mass
Silica ramming mass is composed of raw materials of silicon carbide, graphite and calcined anthracite, some admixtures of super fine powders and binders of fused cement or composite resin. In the compositions of silica refractory ramming mass, aggregates and powders account for a large proportion, while binders and other components account for a very low proportion. For some silica ramming mass material, which even consist entirely of aggregates and powders. Refractory ramming mass is used to directly contact with the melt. So the aggregates and powders should have high volume stability, compactness and erosion resistance. Generally high temperature sintered or melted materials are adopted to make silica ramming mass refractory.
How to Make Silica Ramming Mass
Silica ramming mass is generally rammed by pneumatic picks and also manually tamped. When ramming with pneumatic picks, the wind pressure cannot be lowered by 5 atmospheres. There are several shapes for the hammer head, such as square, rectangular and round. Its general size is between 50 and 80 mm. If the ruler is large, the ramming force is not enough and the compactness is poor, which will affect the performance of refractory silica ramming mass. If it is too small, excessive tamping force is not easy to tamping, which will affect the work efficiency silica ramming mass.
Construction of Silica Ramming Mass
- When ramming, the thickness of the material is 20 ~ 60 mm each time, the pneumatic picks should be perpendicular to the material surface, the hammer head should move continuously in one direction, and the hammer head should overlap one third to one half to avoid leakage. There must also be overlap between each row.
- Tamp each layer of material for four or five times in a row, after reaching uniformity and compactness, the next layer of material can be laid. Roughen the ramming surface preferably before the material is spread, so that the upper and lower layers are tightly connected to prevent delamination.
- Keep carrying out the ramming construction continuously. If the intermittent time is longer, the ramming surface should be tightly covered. When re-construction, the ramming surface should be shaved before ramming.
- After ramming, remove the mold immediately for curing or baking. If it is ramming a prefabricated component or prefabricated block, it must reach the label required by the design before it can be handled.
