Hot Working Manufacturing Process of Large Mine-Used Rotary KilnRolling Ring Forgings

Abstract

Bearing the gravity of rotary kiln barrel and the pressure between riding wheel and rolling ring, the surface defects appeared on casting large rotary kiln rolling ring, which caused large maintenance cost. While the life cycle of the rolling ring would be prolonged by using forging instead. The manufacture processing of large rotary kiln rolling ring was explored for changing casting to forging. The reasonable processing of smelting, forging and heat treatment were established.
