Quenching and tempering treatment usually refers to the quenching and subsequent high-temperature tempering of steel and is a common process in the heat treatment of steel. Its purpose is to improve the mechanical properties of the metal through appropriate heat treatment processes so that it has good comprehensive mechanical properties. The following is a detailed excerpt …

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 …
