The Silica ramming mass manufacturer will show you what are the ingredients of the ramming mass

Silica ramming mass manufacturers tell you that the proportion of granular and powdery materials in the ramming material is very high, while the proportion of binder and other components is very high, while the proportion of binder and other components is very low, or even all It consists of granules and powder. Therefore, the reasonable gradation of granular and powder materials is an important part.

The material and use of the powder require the selection of an appropriate binder. Some ramming materials do not use binders, or only add a small amount of co-solvent to promote their sintering. Binders such as sodium silicate, hexyl silicate and silica gel are commonly used in acidic ramming materials. Among them, borate is mostly used in dry ramming materials. Silica ramming mass manufacturers tell you that magnesium chloride, sulfate, phosphate and its polymers are commonly used in alkaline ramming materials. Higher carbon content is also often used, which can form carbon-bonded organic pitch and resin and temporary binders at high temperatures. Such as dolomite, coal-based ramming materials are mostly combined with asphalt or resin. Among them, the dry ramming materials are more suitable for iron-containing co-solvents. Aqueous solutions such as phosphoric acid and aluminum acid phosphate chloride and sulfate are often used for high alumina and corundum ramming materials, and temporary binders can also be used. Clay ramming materials are sometimes only added with appropriate soft clay, or a small amount of the above-mentioned binders. Carbonaceous ramming materials mainly use binders that form a bond. Various cements are not used in the ramming material.
Granules can be made of various materials depending on the temperature used. The manufacturer of Silica ramming mass tells you that no matter what material is used, since the ramming mass is mainly used in addition to direct contact with the melt, the granular powder must have high volume stability, compactness and erosion resistance. Typically, high temperature sintered or fused materials are used. It should also be insulating for induction furnaces.
The manufacturer of Silica ramming mass tells you that generally no additives such as plasticizers and retarders are added to the ramming mass. It also contains less moisture. When non-water-soluble organic binders are used, there is no water in the mixture. In some ramming materials, refractory fibers are also used as reinforcing materials.
