METHOD FOR CONTROLLING POSITION OF MATERIAL TO BE HEATED IN WALKING BEAM TYPE HEATING FURNACE

摘要

PROBLEM TO BE SOLVED: To surely prevent damage to a furnace wall of a heating furnace by correcting the positional deviation of a material to be heated in the furnace width direction occurring when the material to be heated is alternately placed on a movable skid and a fixed skid in a walking beam type heating furnace.;SOLUTION: Amount of movement of the material 2 to be heated in the furnace width direction when a rotation member 8 makes one revolution in the normal direction, and amount of movement of the material 2 in the furnace width direction when the rotation member 8 makes one revolution in the reversed direction, are each premeasured while the material 2 is placed on a walking beam 4. When amount of relative movement of the material 2 in the furnace width direction with respect to the walking beam 4 exceeds the preset prescribed allowable amount of movement when the rotation member 8 is continuously rotated in the continuous conveyance of the materials 2, the rotation member 8 is continuously rotated in a rotating direction in which the amount of relative movement of the material 2 in the furnace width direction with respect to the walking beam 4 is reduced, thereby the position of the material 2 in the furnace width direction is corrected.;COPYRIGHT: (C)2010,JPO&INPIT
