Information
Spinel ramming mass manufacturer tells you that the ramming material is a semi-dry, bulk refractory formed by ramming. Usually particles and fine powders made of high-alumina materials are made according to a certain gradation and added with an appropriate amount of binding agent, and need to be rammed to obtain a compact structure during construction.
Advantages of Spinel ramming mass:
Spinel ramming mass is mainly used in direct contact with the melt, so the granules and powders are required to have high volume stability, compactness and corrosion resistance. At the same time, the ramming mass of the intermediate frequency furnace has good chemical stability and erosion resistance. Anti-wear, anti-flaking, heat shock resistance.
Spinel ramming mass uses high-iron, high-calcium synthetic magnesia and fused magnesia as aggregates, synthetic magnesia and fused magnesia as fine powder, with a critical particle size of 5-6mm, and uses C2F (ferrite two) in synthetic magnesia. Calcium) is used as a sintering aid without adding any binding agent, and it is made with multi-level ingredients. Spinel ramming mass manufacturer tells you that through ramming construction, the density after construction can be guaranteed, and it can be sintered into a solid whole at an appropriate temperature, and its life span is several times longer than the previous knotting and bricklaying. Under normal circumstances, the one-time life of dry ramming material can reach more than 300 furnaces, and it can be extended to 500-600 furnaces through hot repair, which not only reduces the number of furnace shutdowns, but also significantly reduces the consumption of refractory materials per ton of steel. Spinel ramming mass is made of magnesia raw materials and additives. It has the characteristics of corrosion resistance, erosion resistance, and convenient construction. It is used to fill the joints around the base bricks at the bottom of the ladle and around the base bricks at the bottom of the tundish.
