3~T锤生产线是原齐齐哈尔钢厂为开发锻件产品,扩大生产品种,提高经济效益而确定的“七五”期间的重点技改项目。89年10月破土动工兴建,91年10月交付生产。在几年生产中,吊车轨道压板频繁脱落,给安全生产造成重大威胁,使生产严重受阻。为此应用系统工程认真分析压板脱落原因,采取切实可行措施进行改进。一、摆明问题确定对象 3~T锤吊车轨道固定结构(图1),位号4轨道装在位号1钢筋混凝土上板梁的上面,在每组压板处中间加垫橡胶板(440×150×5)位号2、1块。
3 ~ T hammer production line is the former Qiqihar Iron and Steel Mill for the development of forgings products, expand production varieties, improve economic efficiency and to determine the “seven five” during the key technological transformation projects. 1989 年 89 groundbreaking construction, in October 91 delivered production. In a few years of production, crane track plate frequent off, resulting in a major threat to safety, so that production is severely hampered. For this reason the system engineering careful analysis of platen off reasons, to take practical measures to improve. 1, put the problem to determine the object 3 ~ T Hammer crane track fixed structure (Figure 1), No. 4 track installed in the No. 1 reinforced concrete beam above the board in the middle of each platen rubber mat (440 × 150 × 5) 2,1 block number.
