RUBBER CLAD SQUEEZE ROLLS FOR METAL CLEANING SECTION OF HIGH SPEED LINES OF COLD ROLLING MILLS.

摘要

The present invention is related to a new compounded carboxylated nitrile rubber (XNBR) formulation for rubber clad squeeze rollers. These rubber clad squeeze are used in alkali cleaning section of cold rolling/continuous galvanizing/polymer coating operation of steel sheet.The developed rubber clad rollers with the inventive compounded carboxyleted nitrile rubber (XNBR) formulation can withstand high temperature with dynamic stress strain workability at high line speed. The formulation provides improved results with minimum change in hardness, % volume & weight swell, tear strength and abrasion resistance. The disclosed formulation maintains original physical and chemical properties including surface condition at the prevailing mechanically brutal and chemically aggressive condition.
