Advantages and disadvantages of heat treatment of rolling pins with ultrasonic induction heating equipment

Rolling pins are mostly used in various chain transmission machinery. They often cause friction with other parts during the working process, so they are required to have good strength, toughness and wear resistance. In order to meet this requirement of rolling pins, we commonly use ultrasonic induction heating equipment for heat treatment. Zhengzhou Gou's has been engaged in the production and sales of induction heating equipment for many years. Today, we will briefly talk about the advantages and some defects of using ultrasonic induction annealing equipment for heat treatment of rolling pins.

The rolling pin is quenched and tempered using ultrasonic induction heating equipment: (850-870)℃ . The surface is subjected to ultrasonic quenching and heating at a heating temperature of 840-860°C, followed by rapid water spray cooling and low-temperature tempering.

The advantages of using super audio induction quenching equipment for heating of rolling pins:

1. Fast heating: fast heating speed results in uniform heating, and the heating speed can be adjusted and controlled.

2. Easy to operate: CNC design, the whole machine does not need to be debugged, installation and operation are very convenient, and you can learn it in 5 minutes.

3. Less power consumption: it saves about 70% of power than old-fashioned tube high-frequency equipment. The smaller the workpiece, the less power it consumes.

4. Full protection: equipped with overvoltage, overcurrent, overheating, water shortage and other alarm indications, and automatic control and protection.

5. Good effect: the heating is very uniform, the temperature rises quickly, the oxide layer is small, and there is no waste after annealing.

There are many advantages to using ultrasonic induction quenching equipment for heating rolling pins. However, defects will inevitably occur due to the influence of many factors during the heat treatment process. The defects and preventive measures are as follows:

1. The hardness does not meet the requirements. The reason is that the quenching temperature is low or the cooling rate is slow. We should choose a slightly higher quenching temperature, use a medium with high cooling performance, and avoid the accumulation of rolling pins during cooling.

2. The metallographic structure is unqualified. If the quenching temperature is too high or the holding time is too long, or the cooling process cannot be fully and evenly cooled, it will cause the appearance of structural defects. We should appropriately lower the quenching temperature and shorten the cooling time.
