METHOD FOR PRODUCING ROLLER FOR IRON MILL OF COLD-ROLLED STEEL PLATE BY USING WASTE FIBER AND ROLLER THEREOF

摘要

PURPOSE: A production method for a roller is provided to save production costs by using waste fiber classified as a waste material and to produce the roller satisfying impact resistance, earthquake resistance, heat resistance, chemical resistance and so on. CONSTITUTION: Waste fiber is formed in a planar and nonwoven type of specific thickness by scutching the waste fiber. To have a desired shape of diameter for the planar and nonwoven type waste fiber, a disc is made up by using a die. The disc is soaked in a vacuum impregnation tub for a permeation treatment. Herein, the vacuum impregnation bath is mixed up with a thermosetting resin, a rubber and a vulcanizing agent. The disc is dried in a drier and deposited on a frame for a roller. In a state of depositing the disc, the disc is compressed horizontally. The disc is heated and hardened while keeping a compressed state. Then, the disc is finished in a desired shape by grinding the surface of the hardened disc.
