上钢一厂二转炉车间自1976年4月开始试制投射成型盛钢桶衬,1982年3月试制捣打成型盛钢桶衬,但由于人工拆除困难限制了投射包和捣打包的推广使用。为解决人工拆除整体成型钢包包衬的困难,该厂于1982年9月试制成功QC829型盛钢桶拆衬机。拆除一只投射包包衬仅用15分钟,拆除一只捣打包包衬用时为20分钟,已于1983年9月投入生产使用,完全代替了人工拆除桶衬。
Since April 1976, the steelmaking workshop of the first steel plant of the Company has been trial-produced and projected to shape the steel ladle lining. In March 1982, the ladle forming ladle steel lining was trial-produced. However, due to the difficulty of manual dismantling, the popularization and application of the projectile and tamper packages were limited. In order to solve the difficulty of manually removing the overall shaped steel liner, the factory successfully produced the QC829 steel ladle liner machine in September 1982. It took only 15 minutes to dismantle a projected bag liner and 20 minutes to remove a ramming bag liner. It was put into production in September 1983 and completely replaced the manual removal of the bucket liner.
