电铲提升卷筒的工艺改进

摘要

Based on the requirement on the hoisting drum of electric shovels and workshop practises, the surface of the hoisting drum is hardened by the means of flame heating instead of induction heating, which can improve the product quality , reduce energy consumption and make operation more efficient and safer.%　　根据电铲提升卷筒的要求，结合车间生产实际，将火焰加热表面淬火改为感应加热表面淬火，提高产品质量，降低能源的消耗，实现高效率安全生产。
