Walking beam furnace technology process description 

 

The part before entering the furnace roller→weighing→length measurement_

→position of feeding roller→open the feeding door→hydraulic steel pusher

→billet width measurement→position the billet on the walking beam

→mechanical equipment of the reheating furnace(including hydraulic system),

according to the technology design movement, the billet will be heated in the 

furnace according to the heating process requirement→billet positioning by laser detection point

→signal of steel need→the discharge door rises→to get the steel→billet positioning on the discharge roller

→close the furnace door→descaling rolling.
