Hot online quickly repairs the reaming of the copper opening such as bottom blowing smelting furnace, bottom blowing smelting furnace, anode furnace, etc., and maintains a life of more than one week.
For furnaces such as bottom blowing furnaces in the copper industry, the copper liquid discharge port will have hole reaming problems after a period of use. If the hole is enlarged to a certain extent, it will take a long time to stop the furnace and replace the bricks, and the general repair materials are not easy to repair. Or the repairing effect is poor, which troubles some enterprises and becomes a production bottleneck. To this end, Quantong Kiln has developed a hot-refill material for the copper outlet. , Insert a steel pipe with the same diameter as the original copper outlet at the copper outlet, pour the mixed hot-filling material into the outside of the steel pipe, and properly drain the flow with steel bars. , takes about 20 minutes.
The hot filling material can be firmly bonded with the original furnace lining, and it is made of fused magnesia-chromium material, which has high strength and is resistant to copper liquid erosion and erosion. The repaired furnace mouth can be used for about 10 days.
