A furnace pusher is a key mechanism in steel and other metal production lines, used to discharge hot billets from industrial furnaces. This tool is responsible for pulling the hot billets—which have been prepared for rolling and shaping—out from the end of the furnace and guiding them toward the next production stage.

Function and Mechanism:
The primary mechanism of this tool is based on a rack and pinion system. In this mechanism:
1-Rack: A long rod with teeth on its surface
2-Pinion: A small gear that engages with the teeth of the rack.
As the pinion rotates, the rack moves linearly, pushing the billet forward or backward. This mechanism allows the furnace pusher to discharge heavy billets from within the furnace with high power and precision.

The use of a rack and pinion system in this process ensures high accuracy and precise motion control, preventing damage to the billets or disruptions to the production process. Overall, the furnace pusher acts as a critical component that increases the speed and safety of the billet discharge process.
