Do you know about the medium frequency induction heating furnace used for heating copper billets?

In wire factories and copper processing plants, copper billets are usually induction heated by medium-frequency induction heating furnaces and then extruded into copper wires, copper rods, and pipes.

The technical data of the medium frequency induction heating furnace are as follows:

Copper rod material: TUP copper, 68 copper

Copper rod size: φ63mmx250mm

Copper rod mass: 7kg

Productivity: 3min/piece

Heating temperature: TUP copper - 900℃, 68 copper - 800℃

Medium frequency heating furnace: 100kw, 500hz

Inductor: The inner diameter of the coil is φ125mm, the length is 870mm, and it is wound with a square 10mmx10mmx2mm pure copper tube. The heat-resistant sleeve inside the coil is a silicon carbide tube, and the insulation layer is an aluminum silicate fiber felt.

The medium frequency induction heating furnace is automatically operated and has a temperature measuring device that measures the temperature of the copper rod during the heating process and uses a time relay to control the production rhythm. When starting to feed, the temperature measuring head first leaves the copper rod and rotates at an angle. The feed pusher moves and pushes a copper rod into the sensor. The heated copper rod is pushed out of the sensor and falls onto the roller table. The copper rod is transferred to the end of the roller conveyor, the ejector mechanism rises and flips the copper rod to the discharge chute, and the copper rod rolls to the extruder for extrusion. At the same time of transmission, the feeding pusher returns, and a copper rod rolls down in the feeding chute for the next feeding. The temperature measuring head enters the temperature measuring position and touches the end of the copper rod, which completes one entry and exit. Material operation.
