The large sintering machine how to better advantage
As the main direction of development of the domestic and international sintering technology, large-scale sintering machine sinter quality, low energy consumption, high labor productivity and the level of automation and many other advantages. In order to comply with the development of sintering technology boom of the new century, the domestic steel companiespowder metal set off a major new sintering machine. At the same time, accompanied by the reduction of high-quality iron ore resources, iron ore sintering theory has made significant progress. The construction of large-scale sintering machine guidance, research and development of the integrated operation of the application to meet the large sintering machine technology, to achieve the sintering process intensification, stable operation and production, advanced technology indicators; energy conservation efforts and strengthen sintering production to achieve advanced concepts comprehensive technical and economic indicators and the level of technology to enhance the overall.
Important, in order to give full play to its many advantages, the practice of large sintering machine operation techniques for running large-scale sintering machine. To this end, a high and stable yield excellent cold and hot strength of the sinter reasonable size composition and alkalinity high pass rate target, in advance of a full feasibility study and technical preparation, exploring this premise The the large sintering machine integrated operation technology.
Mixed granulating parameter optimization control technology. Mixed granulation is an important part of the sintering process, its purpose is to mix, add water, wetting and granulation get uniform composition suitable particle size, has good permeability sintering mixed material. Most of the domestic large sintering plant to take a two-stage hybrid 450m2 sintering machine to take the three sections of the mixing step, the beginning of the design that is enhanced granulation, to improve sinter layer permeability into the focus of study and sosintered metallve process problems, both system reliability sex.
Mixing granulation process is influenced by many factors, it is to explore the relationship between the various factors in the operation. Due to the thicker layer of sintered material, the greater the resistance, the higher the negative pressure bellows, a corresponding increase in air leakage rate, to reduce air leakage rate increased difficulty. The sintering machine ventilation system air leakage is mainly reflected in: trolley in the high temperature deformation wear, bellows seals worn elastic subsided, the nose and tail at the bellows separator gap increases with the bottom of the trolley, trolley skateboard skateboarding bellows seal is not Yan gap increases contact between adjacent trolley, ventilation pipes wear out.
