TECHNOLOGICAL PROCESS DESCRIPTION
2.1. Reheating Furnace
Billets coming from casting shop are charged into reheating furnace with pushers. After casting the billet surface temperature comes to ambient temperature because of cooling. So then billets must be reheated in the furnace up to hot rolling temperature which is around 1200-1250oC. Billets moved through discharging side by pusher-force from charging side.
2.2. Rolling Mill Group
Rolling process achieved in 1 stands founded beside to each other. Group is driven by an ac motor. Flywheel passes driving from motor to gear-box and trio gear-box. There are specific grooves on the rolls heated billet or ingot comes to the group from furnace and placed by guides in grooves. While billet passed between grooves on the rolls, cross section of billet decreased pass by pass, this is hot rolling process. Product type changes related to groove shapes on the rolls and pass numbers.
