Introduction to Copper Ingot Solder Manufacturing

  The solder used in brazing is usually in the form of a wire rod, which is extruded from a solder ingot after heating. The extrusion temperature is usually between 400-600°C, and the extrusion temperature varies depending on the material. The traditional heating method is resistance furnace heating, the ingot is put into the furnace through heat conduction and the temperature rises slowly. The induction heating hot-through furnace uses induction heating to make the solder ingot itself heat, the heating speed is fast, and it can realize automatic feeding, pushing and tact time adjustment.

Principle of induction heating

Induction heating is a metal heating technology that uses a high-frequency magnetic field to generate eddy currents inside the metal to heat it. It is one of the most recommended energy-saving and emission-reduction technologies in the country.

Energy saving

No pollution, zero emission

High heating efficiency


 

Process status

For ingot metals, the traditional heating method is usually resistance furnace heating. This process has obvious disadvantages:

1. Warm up a few hours before work. For example, when you go to work at 8 o'clock in the morning, workers will come and turn on the machine in the early morning;

2. High temperature, especially when the furnace cover is opened, the heat radiates rapidly, causing the surrounding working environment temperature to be too high;

3. High-intensity labor. When working, workers need to open the furnace cover, put the ingots into the furnace under the high temperature of the furnace, and take out the heated ingots, and do this repeatedly;

4. Energy waste, frequent opening of the furnace cover causes a large amount of heat to be emitted; the equipment cannot be stopped during intermittent work, such as the resistance furnace must continue to be heated during a noon break; the thermal inertia is poor, and a large amount of residual heat in the resistance furnace is wasted after get off work in the afternoon. Lose.

Application Ideas of Induction Heating Spindle

In order to improve the working environment and achieve the purpose of energy saving and emission reduction, induction heating is currently one of the most suitable heating methods; its technological characteristics are:

1. Good thermal inertia, no preheating is required, heating can be performed at any time, and no residual temperature remains when heating is stopped.

2. To improve the working environment, the principle of induction heating is to let the workpiece heat itself without heat conduction, so there is no large amount of heat dissipation.

3. Reduce labor intensity. The induction heating furnace can realize automatic feeding and pushing. Workers only need to clamp the pushed out spindle into the press at the discharge port.

4. Energy saving, environmental protection, induction heating can be used for immediate heating, and there is no large amount of heat dissipation and residual, so it will not cause energy waste.
