Abstract

Abstract:

BOF slide gate slag stopping technology has the advantage of high success rate in slag stopping，which has been used in many large and medium BOFs in China.This paper introduces the damage reason and improved method for 120 t BOF slag stopping system.The production practice result shows that the service lives and service effects of slide gate and tap hole are both improved.

Key words:

"> BOF, Slag stopping, Tap hole, Slide gate, Damage

CLC Number:
