1. Before starting the intermediate frequency heating furnace, it is necessary to check the pushing and discharging devices, whether the circulating water and air pressure are normal, the limit switch, whether the automatic and manual switch positions are at the required position, and whether the blank on the work table meets the forging requirements. Cooling water is the lifeline of induction furnaces. Always pay attention to cooling water. The outlet water temperature should not exceed 60 °C.
2. After starting the intermediate frequency heating furnace, adjust the heating parameters, and the normal heating production can be performed after the heating parameters are stabilized.
3. For the first time heating in the case of the intermediate frequency heating furnace, the rated power should not be used immediately. The low temperature heating should be used with 60%-75% of the normal power, which can avoid the lining crack of the intermediate frequency heating furnace, and the temperature of the lining should reach 90 °C evenly. When the power is increased to the normal process power, the formal forging operation begins.
4. The billet should be placed correctly during the filling process, and the billet with large deformation should be processed before the furnace can be installed.
5. There should be no blanks for the two parts in front of the medium frequency heating furnace and on the workbench. The furnace worker must sort the remaining blanks heated before leaving work to the bin, indicating the blank specifications and status, and the red in the induction furnace. The material should be forged.
