【摘要】：钢渣是冶炼钢铁过程产生的废物,伴随着我国钢铁工业的飞速发展,我国的钢渣堆存量也飞速增长。据不完全统计,我国废弃钢渣的堆存量已经超过11亿吨,钢渣的实际综合利用率仅为10%,如不对这数量巨大的堆存废弃钢渣回收利用,这些堆存钢渣不仅占用了大量土地,而且钢渣中的重金属元素流失也会对生态环境造成严重污染,这种现象严重制约了我国钢铁工业的可持续发展。因此,对钢渣进行综合利用,不仅有着巨大的环境效益,还会产生巨大的经济效益。本文论述了钢渣粉磨设备的发展历程,对传统粉磨设备进行了系统的对比,分析了各种粉磨设备的优缺点,论证了筒辊磨在钢渣粉磨应用中的先进性。应用公司钢渣粉磨实验系统,对两份钢渣来样进行了粉磨实验。实验结果显示,筒辊磨粉磨的钢渣微粉成品物理性能完全符合国家标准的要求,可以等量替代水泥,并且磨耗和电耗均低于传统粉磨设备,为开展大型粉磨钢渣用筒辊磨机奠定了实验基础。本文通过分析计算出了Φ3800粉磨钢渣用筒辊磨的结构参数和技术参数,并设计了Φ3800筒辊磨的主要结构。Φ3800筒辊磨的主要零部件结构尺寸大、受力复杂,对关键零部件通过ANSYS Workbench软件进行有限元分析,获得了筒体、压辊主轴和压杆承载时的应力和位移分布彩色渲染图,验证了磨机主要零部件的强度和刚度是能够满足使用要求的,为磨机后续深入研究及工程实际应用奠定了基础。
[Abstract]:Steel slag is the waste produced in the process of smelting iron and steel. With the rapid development of iron and steel industry in our country, the amount of steel slag pile up in our country is also increasing rapidly. According to incomplete statistics, the stacking capacity of waste steel slag in China has exceeded 1.1 billion tons, and the actual comprehensive utilization rate of steel slag is only 10%. Without the recovery and utilization of this large number of stored waste steel slag, these stored steel slag not only occupies a large amount of land, but also the loss of heavy metal elements in steel slag will also cause serious pollution to the ecological environment, which seriously restricts the sustainable development of China's iron and steel industry. Therefore, the comprehensive utilization of steel slag will not only have great environmental benefits, but also produce huge economic benefits. In this paper, the development course of steel slag grinding equipment is discussed, the traditional grinding equipment is systematically compared, the advantages and disadvantages of various grinding equipment are analyzed, and the advanced nature of cylinder roller grinding in steel slag grinding is demonstrated. The grinding experiment of two samples of steel slag was carried out by using the steel slag grinding experiment system of the company. The experimental results show that the physical properties of the finished steel slag powder are in accordance with the requirements of the national standard, and the cement can be replaced by the same amount of cement, and the wear and power consumption are lower than those of the traditional grinding equipment, which lays an experimental foundation for the development of a large roller mill for grinding steel slag. In this paper, the structural parameters and technical parameters of 桅 3800 roller mill for steel slag are analyzed and calculated, and the main structure of 桅 3800 cylinder roller mill is designed. The main parts of 桅 3800 cylinder roller mill have large structure size and complex force. The finite element analysis of the key parts is carried out by ANSYS Workbench software, and the color rendering diagram of stress and displacement distribution of cylinder body, roller spindle and pressure bar is obtained. It is verified that the strength and stiffness of the main parts of the mill can meet the requirements of use, which lays a foundation for the further research and practical application of the mill.
