During the lining construction of intermediate frequency induction furnace, the furnace wall shall be inspected after the furnace body construction is completed. Why is the color uneven and there are pits? You may be in this situation for two reasons:

1. The lining is not fully mixed with water, and the workability is not good.

2. The structure of the furnace body is even and loose.

I recommend you 1. Fully mixed with the machine; 2. The lining knot strength should be balanced, uniform and dense. It is recommended to use our patented products and Xinsheng: crucible self-vibrating furnace building machine, and the furnace lining construction effect is better.
