Description

Technical Field

[0001] The utility model relates to the technical field of forging furnaces, in particular to a forging temperature control device for high-chromium steel forgings. Background Art

[0002] Forging is a common process in the machining process. In order to make the workpiece achieve certain characteristics, the workpiece needs to be forged at high temperature. The current forging furnace can be divided into two types: flame heating furnace and electric heating furnace. The metal is heated by different energy utilization methods. High chromium steel (high chromium cast iron) is widely used in various high-strength and high-wear-resistant parts due to its good wear resistance and corrosion resistance. High chromium steel forgings require precise temperature control during the forging process in the forging heating furnace to ensure their good mechanical properties and internal structure.

When in use, the workpiece is placed on the feed plate, and the electric push rod is started to move the workpiece into the preheating box to preheat the workpiece, so that the heating furnace body can quickly heat the workpiece.
