Correct operation of high-frequency heating and quenching machine tools will save energy

The reason for the selection of the high-frequency heating and quenching machine tool is either the improper use of the workpiece, or the improper operation, which may cause the power loss of the equipment. Therefore, it is recommended that you choose the appropriate frequency and power of the high-frequency heating and quenching machine tool. The frequency should be in line with the penetration heating, and the power should meet the standards of short heating cycle and low heat conduction consumption. The selection principle of high frequency heating and quenching machine tools is to choose high frequency conversion efficiency, and the main accessories should also be considered. For example, the frequency conversion efficiency of solid-state high-frequency power supplies is higher than that of tube high-frequency power supplies. Under normal conditions of product technology, solid-state power supplies should be used as much as possible. In solid-state power supplies, transistor power supplies are more efficient than thyristor power supplies, so IGBT or MOSFET can be preferred. power supply.

When using a high-frequency heating and quenching machine tool, the requirements for the equipment are: high load factor and short idling time. If multi-axis and multi-station heating can be used at the same time, then the multi-axis and multi-station structure is preferred. Taking a large-scale half-shaft type machine as an example, one-time heating is more energy-efficient than scanning quenching. The sensor performance is also related to the solution, the performance is above 80%, and the performance of the bad sensor is below 30%. Choosing a good sensor is also very important.
