How to use electric furnace lining to repair electric furnace

The intermediate frequency furnace lining will always be damaged due to long-term use. How should it be repaired at this time? Today, the furnace lining manufacturer Luoyang Quantong Kiln Industry Co., Ltd. will take you to understand:

A. Repair of cracks or damage at the joint between the tap hole refractory material and the furnace wall. It can be repaired by pushing and beating with unshaped refractory materials, and charcoal should be used for drying when the repair scale is large.

B. The repair of sidewall cracks is generally, and the cracks below 1mm can be used without repairing; the cracks above 1mm, especially in the horizontal direction, need to be repaired. The refractory materials for building furnaces that can be added with boric acid and mixed evenly can be screened , For a long time, the intermediate frequency furnace is filled with tools such as iron wire. And the surface after the filling is smoothed with wet mixed sand with water glass added.

C. Repair of sidewall damage or small-scale corrosion. Remove the slag and after the iron residue, apply water glass. Then use the mixed refractory material with 5%-6% water glass to tap and repair, or repair with A1 unshaped refractory material. Corrosion When the scale is slightly larger, the model will be released for repair.

D. The repairing furnace bottom can be tamped by adding the same amount of boric acid as the newly built furnace and mixing evenly with the refractory material of the intermediate frequency furnace. The repairing of the sloped part of the side wall needs to be installed outside. The diameter is 5060mm smaller than the furnace diameter, and the height is about 100mm higher than the damaged part. Use a vibrator for tamping, and the thickness of each layer is 2030mm. 10mm higher, and then trim the upper plane to a certain slope.
