IF induction furnace furnace lining
可用在炼铝，铸钢，炼铜 General introduction can be used in aluminum, steel, copper
This product is a refractory material for quartz coreless induction furnace, the material is acidic. The addition of a part of fused silica on the basis of silicon ramming material has significantly improved the expansion disadvantages of the furnace lining. The rise of the furnace lining has been significantly reduced during the oven and no cracks have occurred during the cold furnace. It is characterized by high purity of the raw materials, reasonable grading, Resistant to rapid cooling and rapid heating, especially suitable for intermittent operation of large medium frequency induction furnaces. This material is a pre-mixed dry tamping compound. The boric acid or boric anhydride content has been formulated according to customer needs, and users can put it into use directly. Product grades YSS-140, YSS-145, YSS-150, YSS-155, YSS-158, YSS-160, YSS-165, YSS-170 are suitable for melting temperatures of 1400 ° C-1800 ° C.
There is no crack in the cold furnace. It is characterized by high purity of raw materials, reasonable grading, and resistance to rapid cooling and rapid heating. It is especially suitable for intermittent operation of large-scale induction furnaces.
The correct furnace building, oven and sintering process is the key to ensure the normal operation of the furnace lining. Before building the furnace and oven, please refer to the "Instruction of the furnace sintering process of Henan Ruishi Refractories".
