Vaschenko S. Development of scientific bases of production of raw materials for the steel industry by briquetting

Technology for producing metallurgical briquettes. Developing a holistic method of choice of production technology of metallurgical briquettes. Setting and conducting experiments in the laboratory, experimental data processing using computer programs, mathematical modeling of processes. On the basis of the analysis of small-fraction raw materials and industrial waste, as well as their use of advanced technologies in metallurgy formulated requirements for briquettes properties. On the basis of assessment of the properties of raw materials on compaction index their systematization is developed. Found that an indicator that determines the distribution of charge group's systematization is pycnometric density. Defined range of values for each density pycnometric selected group. The analytical dependence of the parameters on the properties of sealing the charge, based on which an analytical method for estimating the influence of the properties of the charge that the press on their compactness. An analytical expression for the dependence of the compaction pressure compaction factor that allowed the development of an analytical method for determining the resistance to compression of the charge. The conditions of choice rational scheme of compaction are formulated. The dependence of the parameters of compaction from the properties of charge under multiple loads is set. The methodical approach, which allows using a piecewise - linear dependence of the compaction pressure from compaction factor allocate stage deformation processes. As an indicator of defining the boundaries of priority development stages, adopted gradient changes the function k on piecewise - linear sections depending on the compaction pressure compaction factor. Established ranges of gradient k, defining appropriate boundaries stages. It is possible to create experimental and analytical method for determining parameters of multiple compressions of raw materials. Taken together, these results allowed the work to create a comprehensive method of selection metallurgical briquettes production technology which was used in the development process procedures for designing the production of briquettes metallurgical purposes, as well as creating technical documentation for manufacturing forging equipment. Metallurgy. Implemented.
