Abstract
PURPOSE: To reduce the fishtail part length produced at the trailing end of material and suppress the build-up of dog-bone part by coating the lubricating material for lowering the coefficient of rolling friction on vertical roll surfaces at the time of performing broadside reduction rolling through the use of the vertical rolls.
CONSTITUTION: When material 1 is bitten to vertical rolls 4, it is accomplished in the absence of lubrication but after the biting of the material 1, the confirmation of the bite by the signal of a load cell 8 causes the valve 9 of a nozzle 5 for lubricant coating is opened and the lubricating material is coated from the nozzle 5 on the roll 4 surface. As a result of this, the rolling through the use of the lubricating material is done after the biting of the material and since this becomes the broadside reduction rolling of a smaller coefficient of friction between the material 1 and the rolls 4, the rolled material of the small fishtail length at the trailing end and dog- bone end part length of the material 1 is obtainable.
