不同因素对布料溜槽的磨损影响价值分析

大型高炉布料溜槽所处工作环境恶劣,输料时间较长,且受多种因素影响,其磨损情况非常严重。通过建立基于离散元仿真的溜槽磨损数学模型,研究某钢铁企业大型布料溜槽的磨损情况,找出布料溜槽的主要磨损部位。利用该模型分析不同的溜槽倾角、物料粒径和物理特性等影响因素,以探究溜槽磨损的规律。研究结果表明,溜槽的主要磨损是冲击磨损区,磨料磨损区较轻,并且随着溜槽倾角增加,物料粒径、硬度增大,尖角边缘过多均增加其平均磨损深度。本研究为减少溜槽磨损方面的结构改进和正确使用提供一定的参考。

Value analysis of influence of different factors on wear of distributing chute

Aiming at the harsh working environment where the large blast furnace distributing chute is located, and the feeding time is long, and it is affected by many factors, its wear is very serious. A mathematical model of the chute wear based on the discrete element simulation was established to study the wear of a large-scale distributing chute in an iron and steel enterprise, and the main wear parts of the distributing chute were found. This model is used to analyze the influencing factors of different chute inclination angles, particle size and physical characteristics of the chute to explore the rule of chute wear. The research results show that the main wear of the chute is the impact wear area, and the abrasive wear area is lighter. With the increase of the chute inclination, the particle size and hardness of the material increase, and the sharp edges increase the average wear depth, which provides a certain reference or reducing the structure improvement and correct use of the chute.
