[0002] The existing electromagnetic heating technology is not very mature, and has the following disadvantages: large heat loss, the traditional electric heating industry generally adopts resistance wire, electric heating rod, electrode and quartz heating methods, and this traditional heating method, its thermal efficiency In comparison, resistance wires, electric heating rods, electrodes and quartz mainly generate heat by themselves after being energized and then transfer the heat to the barrel or container, thereby heating the objects. The heat utilization rate of this heating effect is the highest. Only about 50%-80%, heat loss is as high as 20%-50% or more; short service life: large amount of maintenance

Because the electric heating tube uses resistance wire, electric heating rod, electrode and quartz to generate heat, its heating temperature is as high as about 200 degrees, the thermal lag is large, and it is difficult to accurately control the temperature. The resistance wire, electric heating rod, electrode and quartz are easy to burn out due to high temperature aging
