Therefore, it is necessary to use iron stainless steel appliances that can absorb electromagnetic waves, but the price of iron stainless steel appliances is often higher than Aluminum alloy appliances' and the heat transfer efficiency of iron is only about one-third of that of aluminum alloy, so the heating effect is far less than that of aluminum alloy appliances.有 有 中 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 2007 On the metal piece, the metal piece is formed into a one-pot body according to the mold, and the metal piece is simultaneously adhered to the bottom surface of the pot body by high pressure. The high-pressure forging technology can improve the density and strength of the pot body. In addition, the forging can also strengthen the joint effect between the magnetic metal sheet and the bottom surface of the pot body, thus providing a more conductive material for the magnet. However, it has the following disadvantages: ^ 1. Although the magnetic conductive metal sheet strengthens the joint effect with the bottom surface of the pot', but after a long time of use, there is also a risk of falling off. 201024000 2·The surface is not flat, it can't be heated evenly, the electromagnetic wave is easy to scatter, and the heating effect is poor.
