近几年来,莱钢炼铁厂的工艺技术和设备管理水平不断提高,设备运行状态长期稳定受控,为生产的连续、稳定、高效提供了坚实可靠的设备支撑。在推行“121”设备管理体系过程中,提出“600”的设备管控目标,抓好设备点检定修等基础管理工作,大力开展设备管理创新和技术创新,维修模式也实现了由“计划检修”向“预知维修”的转变。高炉的休风率指标实现了持续优化提升,高炉的定修周期达到6个月,并且定修间隔内设备故障休风率、慢风率双为零,为炼铁设备管理提出了新思路。
In recent years, the technology and equipment management of Laiwu Steel’s ironworks have been continuously improved. The operation status of the equipment has been steadily controlled for a long period of time, providing a solid and reliable equipment support for the continuous, stable and efficient production. During the implementation of the “121” equipment management system, the company put forward the goal of equipment control of “600”, did a good job of basic management such as equipment check and repair, vigorously carried out equipment management innovation and technological innovation, and the maintenance mode was also realized “Planned maintenance ” to “predicted maintenance ” change. The indicator of the wind-off rate of the blast furnace achieved continuous optimization and improvement, and the repair cycle of the blast furnace reached 6 months. Moreover, the failure wind-down rate and the slow-down rate of the equipment during the repair interval were both zero, thus putting forward new ideas for the iron-smelting equipment management.
