Electricity saving principle of buffer modulated wave aluminum melting furnace
The traditional heating industry generally uses resistance wire and quartz heating methods. This traditional heating method has relatively low thermal efficiency. The resistance wire and quartz mainly rely on electricity to generate heat by themselves and then transfer the heat to the barrel. , So as to achieve the effect of heating objects. The maximum heat utilization rate of this heating effect is only about 50%, and the other 50% of the heat is dissipated into the air. The power loss of all traditional resistance wire heating methods is as high as 50%. . By electromagnetic induction heating, the magnetic field is generated by the electric current to make the ferrous metal pipe heat itself, and the heat insulation material is added to prevent the heat from the pipe from dissipating, the heat utilization rate is as high as 95%, and the energy saving effect can reach 50% in theory. %, but considering that the energy conversion efficiency of electromagnetic induction heating controllers of different qualities is not the same, as well as different production equipment and environments, the energy-saving effect of all electromagnetic heating can generally reach at least 30%, and the highest can reach 70% .
