Description

technical field [0001] The invention relates to the technical field of electromagnetic induction heating, in particular to an electromagnetic induction heating device for aluminum and magnesium alloys and a use method thereof. Background technique [0002] The principle of electromagnetic induction heating is that the alternating current generated by the induction heating power supply generates an alternating magnetic field through an inductor (that is, a coil), and a magnetically permeable object is placed in it to cut the alternating magnetic force line, thereby generating an alternating current (that is, an eddy current) inside the object. , The eddy current makes the atoms inside the object move at high speed and irregularly, and the atoms collide and rub against each other to generate heat energy, thus heating the object. It is a heating method that converts electrical energy into magnetic energy, so that the heated steel body induces magnetic energy and generates heat....

Problems solved by technology

At present, common heating devices for aluminum and magnesium alloys generally use coal or gas as a heat source for heating. This method will cause environmental pollution. In order to improve this problem, more auxiliary equipment is required for processing, resulting in complex equipment and processing. The cost is high, even if it is treated, it can only reduce pollution, and there is still the problem of pollution, or use electromagnetic induction to heat the alloy to avoid pollution. In the heating process, copper tubes are generally used to make heating coils, and then work Cool the copper pipe with water at the time to protect the copper pipe from being blown, but there is a certain safety risk when passing the copper pipe with water, and the heat lost by the copper pipe itself will be taken away by the cooling water, and the waste heat cannot be recovered. Safety performance It is relatively low, and the effect of energy saving and environmental protection is not ideal, which brings great inconvenience to the heating work. Therefore, we propose an electromagnetic induction heating device for aluminum and magnesium alloys and its use method
