銅棒感應加熱爐

In the wire factory and copper processing plant, the copper billet is induction heated and extruded into copper wires, copper rods and pipes. According to the diameter of the copper billet, select the appropriate current frequency for induction heating.

Figure 1249 shows the copper rod induction heating furnace, and its technical data are as follows.

Copper rod material: TUP copper, 68 copper

Copper rod size: 63mm x 250mm

Copper rod quality: 7kg

Productivity: 3min/piece

Heating temperature: TUP copper 900

68 Copper One 800

Intermediate frequency power supply: 100kW, 500Hz

Inductor: coil inner diameter © 125mm, length 870mm, wound with a square 10mm x 10mm x 2mm pure copper tube. The heat-resistant sleeve in the coil is a silicon carbide tube, and the thermal insulation layer is aluminum silicate fiber felt.

The induction heating furnace is automatically operated and has a temperature measuring device, which measures the temperature of the copper rod during the heating process, and uses a time relay to control the production cycle. When starting to feed, the first step is to move the temperature measuring head away from the copper rod and rotate an angle. The feeding pusher moves and pushes a copper rod into the sensor. The heated copper rod is pushed out of the sensor and falls on the spoke. The road conveys the copper rod to the end of the spoke channel, and the ejector mechanism rises to turn the copper rod to

On the discharge chute, the copper rod is rolled onto the extruder for extrusion. While conveying, the feeding pusher retreats, a copper rod is rolled in the feeding chute to prepare for the next feeding, and the temperature measuring head enters the temperature measurement position and touches the end of the copper rod, which completes one in and out Operation of materials.

Figure 12-50 shows an intermediate frequency induction heating production line for copper rods manufactured abroad. In order to make the heating temperature of the copper rods uniform, a holding furnace is installed on the production line. The power of the production line is 1650kW, and the maximum output is 7000kg/h.
