The selection of furnace construction technology and furnace baking and sintering technology should ensure that a reasonable three-layer structure is obtained after the furnace lining is sintered, that is, the initial thickness of the sintering layer, semi-sintering layer and buffer layer is roughly 1/3 each. This is an indispensable condition for the furnace lining to excerpt …

Due to the provisions of power supply policies in my country, the transformers used for industrial electricity are generally S7 and S9 transformers, with a secondary voltage output of 380V. The secondary output voltage of foreign industrial furnaces is 650-780V. It can be seen that if a special transformer dedicated to medium-frequency induction furnaces is excerpt …

What are the problems with energy saving in medium frequency induction furnaces? A. Selection of different capacities and frequencies. B. Matching of rated power. C. The influence of the purity and carrying area of ​​the induction coil and water cable on power consumption. D. The influence of scale and how to deal with it. E. excerpt …

3.2 Control of S and N3.2.1 Control of w(S)There is no S source for smelting cast iron in medium frequency furnace, and the w(S) content of molten iron is low. Therefore, it has great advantages for producing ductile iron, but for gray cast iron, low S and high Mn will increase casting stress, greatly increase excerpt …

Overview:SCR intermediate frequency power supply device, referred to as SCR intermediate frequency device, is a power supply device that uses the switching characteristics of SCR to convert 50Hz power frequency current into intermediate frequency current. It is mainly used in induction melting, induction heating, induction quenching and other fields. widely used in.Its advantages are:
