Problems solved by technology

The reasons for the breakage of the ditch are as follows: First, the copper liquid in the copper mold of the melting channel is not enough when the furnace is stopped, resulting in the cooling and contraction of the copper mold of the melting channel, and there is not enough copper liquid to replenish the ditch; the second is that the copper solution remains When the furnace is turned on, the upper column of the copper mold of the melting channel cannot be melted in time, resulting in a broken channel. There is no copper liquid feeding and the ditch is broken. The fourth is that there is scum in the copper mold of the melting channel and the ditch is blocked.

Embodiment 1

[0021] A method for repairing the melting channel copper mold of the induction body of a cored power frequency induction furnace. When the melting channel copper mold breaks at B, the specific operation steps are:

[0022] a. Drill 8 holes with a diameter of Φ30 in the broken channel of the copper mold of the melting channel, measure the depth of the fault 6 of the copper mold of the melting channel, and calculate the volume and weight according to the measured value of the fault depth of the copper mold of the melting channel.

[0023] b. Weight calculation

[0024] If the measured depth of the fault 6 of the copper mold of the molten channel is 3cm, the copper mold of the molten channel is 12cm wide and 11cm thick, and the required copper powder volume is 3*11*12=396cm 3 .

[0025] Required copper powder weight = copper mold fault volume 396cm 3 ×8.9 g / cm 3 (Density of solid copper) = 3000g.

[0026] Solid copper has a density of 8.9 g / cm 3 , the density of copper powd...

Embodiment 2

[0033] A method for repairing the molten channel copper mold of the induction body of a cored power frequency induction furnace. When the molten channel copper mold is broken at A, the specific operation steps of the broken channel are as follows:

[0034] a. Drill 8 holes with a diameter of Φ30 in the broken channel of the copper mold of the melting channel, measure the depth of the fault 6 of the copper mold of the melting channel, and calculate the volume and weight according to the measured value of the fault depth of the copper mold of the melting channel.

[0035] b. Weight calculation

[0036] If the measured depth of the fault 6 of the copper mold of the molten channel is about 3cm, the copper mold of the molten channel is 6cm wide and 11cm thick, and the volume of copper powder required is 3*11*6=198cm 3 .

[0037] Required copper powder weight = copper mold fault volume 198cm 3 ×8.9 g / cm 3 (Density of solid copper) = 1500g.

[0038] Solid copper has a density of...

Embodiment 3

[0045] A method for repairing the molten channel copper mold of the induction body of a cored power frequency induction furnace. When the molten channel copper mold breaks at C, the specific operation steps are the same as those in Embodiment 2. The difference from Example 1 is the calculation of volume and weight.

Abstract

The invention discloses a method for repairing a melting groove copper mold for an inductor of a core frequency induction furnace. According to the method, a melting groove can conduct electricity and smooth melting can be realized in initial melting; and finally normal production is realized. Holes are drilled in a groove breaking part of the melting groove copper mold; 50-mesh to 200-mesh conductive copper powder is filled into the groove breaking part; the copper powder is hit firmly; a conical copper rod is embedded in the drilled holes and knocked firmly; cut fine copper pieces are firmly embedded into the edge part of the conical copper rod; after a hydropower test is passed, power is transmitted to turn on the furnace until the melting groove copper mold can realize normal production. By the method, the reuse of the inductor of the core frequency induction furnace is ensured; the service life of the inductor is prolonged; the furnace building cost and the furnace hitting cost of the core frequency induction furnace are saved; the production cost of a product is reduced; and the time efficiency in the production is achieved.

Description

technical field [0001] The invention belongs to the technical field of repairing the copper mold of the melting channel of the induction body of a cored power frequency induction furnace, and mainly relates to a method for repairing the copper mold of the melting channel of the induction body of a cored power frequency induction furnace. Background technique [0002] Among the main equipment for the production of copper alloys, the power frequency cored induction furnace adopts the large-section jet flow melting channel mode recognized by the same industry in the world, which can effectively prevent the melt from overheating and cause the quality of the ingot to deteriorate, and the melt The full flow and stirring of the body ensures the full uniformity of the chemical composition. The melting channel of the induction body is the heat source center for the electromagnetic induction of the power frequency cored induction furnace. The melt in the melting channel conducts heat ...
