During the use of the induction melting furnace, the furnace ring will be burned through, which will cause the overflow of cooling water, leading to the shutdown of the furnace, which not only delays the production volume but also increases the cost of the enterprise. In order to better use the induction melting furnace, we need to master the repair method of the induction melting furnace ring and the reason for burning through.

First, the reason for the burn-in of the induction melting furnace

The body of the induction melting furnace consists of 4 main parts: the furnace shell, the induction coil, the furnace lining and the tilting furnace device. The furnace shell is made of non-resilient material. The induction coil is made of rectangular hollow copper coils in a spiral shape. Cooling water flows through the tube. The lead ring is connected to the water-cooled cable, the furnace lining is close to the induction coil, and the tilting white tilting furnace gearbox of the furnace body is directly driven. Due to process or operation reasons, the ring is sometimes burned through by the iron crossing, causing a thermal stop furnace.

During the use of the induction melting furnace, the failure of the furnace ring to be burned through repeatedly occurs for two main reasons:

1. It is the careless operation or the furnace nozzle is too short when the pouring furnace is pouring, and the splashing molten iron adheres to the furnace ring and burns through;

2: After the furnace lining is burned through, the molten iron overflow causes the furnace ring to burn through.

Second, the induction melting furnace ring repair method

After the furnace ring is burned through, the cooling water overflows, and the furnace must be stopped for repair immediately. Because the furnace ring is installed in the furnace shell, it is inconvenient for welding and repair, and it needs to be dismantled for repair. The previous repair process of the furnace ring was: pouring iron out of the furnace → stopping the furnace → cooling → knocking off the furnace lining → taking out the furnace ring → welding the welding ring → installing the furnace ring → building a new furnace lining → oven → opening the furnace, this repair method Waste at least one furnace lining, three shifts of man hours, and more electricity.

Here is an adhesive method to repair the furnace ring, which is more energy-saving and time-saving. The furnace can be temporarily stopped, and at the same time, the copper sheet with a thickness of 1-2 mm should be cut into small pieces, the area of which should be slightly larger than the area of the burner crack, and then use a saw blade or a hand wheel to remove the residue on the burner's burner, and sand it with sandpaper. , Quickly mix the shaped epoxy resin with the curing agent, the trimmed copper sheet sticks to the cracked area of the furnace ring, and after a few minutes of curing the epoxy resin, you can form a very high furnace ring bonding strength. Then you can start the furnace again.
