武钢1 580mm生产线粗轧R2入口推床在日常生产过程中出现多次油缸底层基础松动、地脚螺栓断裂的情况,造成设备损坏频繁,严重影响正常的生产和产品质量。虽做了几次修复加固,但仍无法彻底解决基础松动螺栓损坏的问题。为了彻底消除隐患,保证正常生产,针对粗轧R2入口推床基础螺栓断裂的问题,从根源入手分析查找原因,分别对油缸基础强度进行校核,液压系统进行综合分析以及电气控制程序进行全面分析优化,最终查找出问题根源,彻底解决了推床基础的问题,有效确保了R2入口推床的使用可靠性,保证了轧制节奏和稳定性,效果十分理想。
In the daily production process, the roughing rolling R2 entrance pusher of 1 580mm production line in WISCO appeared many times that the bottom foundation was loosened and the anchor bolts were broken, causing frequent equipment damage and seriously affecting the normal production and product quality. Although the repair done several times to strengthen, but still can not completely solve the problem of loose bolts on the basis of damage. In order to completely eliminate the hidden danger and ensure the normal production, according to the rupture of the base bolt of the rough rolling R2 entrance pusher bed, the root cause is analyzed, the base strength of the cylinder is checked, the hydraulic system is comprehensively analyzed and the electric control program is analyzed comprehensively Optimization, and ultimately find out the root cause of the problem, completely solve the problem of pusher bed foundation, effectively ensuring the reliability of R2 entry pusher bed, ensuring the rhythm and stability of rolling, the effect is very satisfactory.
