What to pay attention to during the use of intelligent induction heating equipment
In the heating and manufacturing process of the reputable intelligent induction heating equipment, the main reason for the deformation of the workpiece is the internal stress in the steel or the external stress applied to the workpiece from the outside. The internal stress is caused by the uneven heating or cooling rate of each part of the workpiece during the heating process of the intelligent induction heating equipment, and the uneven temperature distribution of each part of the workpiece, that is, the thermal stress and the phase change stress. What are the things that need to be paid attention to during the use of the intelligent induction heating equipment?
What to pay attention to during the use of intelligent induction heating equipment
1. Pay attention to the different heating methods for different workpieces
First, the induction heating process and the resistance chip heating process have different heating methods for the workpiece. When the intelligent induction heating equipment is heating, the induction cable is wound evenly, and the energy directly acts on the workpiece. The heating area of the workpiece is located on the surface and below, and heat is transferred to the interior of the workpiece and its parts through heat conduction. The temperature spreads evenly, and the temperature gradient of the inner and outer walls is small. Resistor heating requires a full circle around the workpiece. Each resistor generates heat independently. The heat depends on the contact between the resistor and the workpiece by heat conduction, or indirectly transmitted to the workpiece by heat radiation without contact, and the workpiece is heated unevenly. Although the damage of a single electric heating plate does not affect the work of its electric heating plate, it will lead to the formation of uneven workpiece temperature field, resulting in thermal stress and deformation.
2. Pay attention to the high precision of temperature control
Secondly, the heating rate, cooling rate and temperature control accuracy of the workpiece under the induction heating process are much higher than that of the resistance piece heating. Intelligent induction heating equipment The output power of different heating methods for the workpiece can be continuously adjusted according to the actual temperature of the workpiece, the temperature control accuracy is high, the resistance piece heating has no such function, and the temperature control accuracy is low. In this situation, the intelligent induction heating equipment has different heating methods for the workpiece. The induction heating can ensure the average temperature of the internal and external parts of the workpiece during each stage of heating, heat preservation and cooling of the workpiece, which minimizes the generation of thermal stress and Deformed appearance.
All in all, the things that need to be paid attention to during the use of intelligent induction heating equipment are to pay attention to the different heating methods for different workpieces, and pay attention to the temperature control accuracy.
