APPARATUS AND A METHOD FOR PREVENTING DROOP OF A MATERIAL AND REDUCING SKID MARKS IN A WALKING BEAM HEATING FURNACE

摘要

PURPOSE: An apparatus and a method are provided to prevent droop of a material and reduce skid marks in a walking beam heating furnace by repetitively raising and lowering a movable beam according to the specification of a material in an idling state of the walking beam heating furnace.;CONSTITUTION: An apparatus for preventing droop of a material and reducing skid marks in a walking beam heating furnace comprises a server(100), two movable beams(300a,300b), a drive unit(400), and a controller(600). A material charged in the walking beam heating furnace is carried by a charge roller(700a), and a pusher(800) charges the material into the furnace body by the back-and-forth motion. The movable beams carry the material from the charge side to the exit side by ascending, moving forth, descending, and moving back in sequence. An exit roller(700b) carries the material to an exit extractor(900). Three stationary beams(200a,200b,200c) and the movable beams alternately contact the material in order to prevent skid marks. The drive unit includes motors(400a,400b) and pulse generators(500a,500b).;COPYRIGHT KIPO 2010
