What is the repair method for the cracking of the experimental electric furnace

1. Repair method for cracks or damage at the joint between refractory material and furnace wall:

Uncertain refractory materials can be used to push and repair, and when the repair range is large, it should be dried and then used.

2. The method of repairing the broken hearth furnace wall:

The method of repairing the inner wall damage or small-scale erosion of the experimental electric furnace is to remove the slag and residual iron, and then apply water glass. Then use the mixed refractory material added with 5%-6% water glass to patch and repair the irregular refractory material. When the corrosion range of the wall of the tubular electric furnace is a little larger, it is repaired.

3. Repair method of furnace bottom damage:

The repair of the furnace bottom of the experimental electric furnace can be fixed by adding the same amount of boric acid as the newly built furnace and mixing the experimental electric furnace refractories evenly.
