Method for melting high aluminum weak magnetic metal raw material by induction melting furnace
When the induction melting furnace continuously melts high-aluminum weak magnetic metal raw materials, when all the high-aluminum weak magnetic metal raw materials in the furnace are melted into liquid molten steel, when the temperature reaches 1530 ℃ -1540 ℃, a silicon calcium alloy (Ca3ISi60) is added to the liquid surface. Add silicon to each furnace
The weight Q of the calcium alloy is: Q = T × (M-G) × 1000 × 0. 617, where M is the content of Al element of the high-aluminum weak magnetic metal raw material melted by a certain furnace, and G is the same kind of melting in the previous furnace The high-aluminum weak magnetic metal raw material is obtained by sampling and analysis before the furnace, and the average value of aluminum content is obtained. T is the weight of the high-aluminum weak magnetic metal raw material melted by the furnace. The method for melting high-aluminum weak magnetic metal raw materials by the induction melting furnace is simple and easy to operate, and can obviously increase the furnace lining life of the induction melting furnace when melting high-aluminum non-magnetic raw materials.
