Preparation before lining knotting of induction furnace

1. Coil coating and furnace top ring block shall be dried in advance.

2. The inner lining of the induction ring of the induction furnace consists of glass fiber cloth, mica plate and asbestos cloth, which is tightly fixed on the inner side of the inductor with the expansion ring, and the insulation layer of the furnace bottom is paved with asbestos cloth.

3. Select the furnace building materials, add the binder and stir evenly. In order to prevent moisture absorption and impurities, the furnace building materials should be covered and used in a short time.

Before adding boric acid or boric anhydride, it should be screened through a 0.5mm mesh to avoid the mixing of larger particle size, which will cause too much binder content in local area and affect the quality of furnace lining.

5. The construction site should be cleaned up, and the tools for knotting should be complete.

6 check the crucible mold size and whether there is an acute angle at the lower conical part, the surface shall be free of concave convex and rust, and the welding place shall be polished.

7. Uniform vent holes are drilled around the crucible mould, with a diameter of 2-3mm
