Huaxin Electric Furnace is one of the excellent induction furnace manufacturers in China. After nearly 30 years of production practice, the following rules have been summarized The medium frequency heating furnace is an induction heating device for the purpose of heating metal forging or quenching and tempering heat treatment. When used for heating before forging, the heating temperature is generally 1200 degrees, and when used for quenching and tempering heating, the heating temperature is generally within 1000 degrees.

Huaxin Electric Furnace is one of the excellent induction furnace manufacturers in China. After nearly 30 years of production practice, the following rules have been summarized: 1. Hydraulic system: The hydraulic system of the medium frequency, coreless induction furnace is used to pour molten metal out of the furnace, and to open and close the furnace cover. To ensure reliable work, the hydraulic station of the electric furnace should be equipped with two main pumps of the same specification (one for use and one for backup). The inlet end of the tilting furnace hydraulic cylinder needs to be equipped with a throttle valve to prevent the furnace body from falling suddenly due to the loss of pressure in the hydraulic system. When the power supply is interrupted for a long time, the molten metal in the electric furnace may cool and solidify. This situation may damage the furnace lining. It is very dangerous to melt the solidified metal in the furnace by operating the electric furnace.
