Rolling pins are mostly used in various chain transmission machinery, and they are subjected to great alternating extrusion stress and multiple impact forces during operation, so they often fail due to wear and tear. In order to avoid this phenomenon, many manufacturers use super-audio frequency induction hardening machines for quenching heat treatment. After quenching, the rolling pin has high wear resistance and fatigue resistance, and has a certain combination of strength and toughness, which meets the needs of the work.
The super-audio frequency induction hardening machine is used to quench and heat-treat the rolling pins. The operation process is very simple. Just put the rolling pins to be quenched into the sensor, and then start the equipment to heat to 840-860°C, and then quickly spray water to cool it. , no other operations are required, very simple. Even better, the equipment adopts non-contact induction heating, which greatly reduces the deformation of rolling pins.
The equipment adopts IGBT inverter power device, which is highly efficient and energy-saving, and the heating is easy to control. The heating current value and heating voltage value can be set, and the current, voltage, power and frequency are all displayed, and the operation is intuitive, simple and convenient. Even better is that after quenching by this equipment, the rolling pin has no cracks and deformation defects, no oxidation and decarburization, and the effect is far superior to that of traditional equipment.
