| Popis: | Production of pipes by the method of hot extrusion is characterized by high level of resource capacity and considerable cost of original raw materials. In this connection wastes and metal loss have a considerable effect on the products cost. This factor stipulates the importance of objective and scientifically based planning of metal consumption. Some peculiarities effecting on the level of wastes and metal loss during pipe production at hot extrusion facilities considered. Methodical approaches to planning and assessing metal consumption at the manufacturing of hot-extruded pipes based on the computational and analytical method are outlined. The advantage of using the computational and analytical method of metal consumption rationing was shown. An explanation of the features of the implementation of the computational and analytical method used for modern rationing using information processing systems based on electronic computers is given. The basic materials of the instruction on the rationing of the consumption of ferrous metals at the production of steel pipes, used for a single-stage production scheme, are presented, noting its advantages and disadvantages. The historical aspects of research in the field of rationing of metal consumption at the TMK Group plants considered. A detailed list of literature sources is provided, including corporate materials of TMK Group, used to create programs for metal consumption rationing at the production of hot-extruded pipes at PED-2 of VTZ. The elements of the developed mathematical model used to create a software product are given. The complex of functional capabilities of the program is described, which are necessary for the operative automated calculation of particular consumption coefficients, consumption rates and structure of metal wastes by technological stages. A conclusion is made about the effect of the implementation of the obtained model, expressed in the organization of the process of technical rationing that meets the current requirements. This process of technical rationing makes it possible to establish scientifically and technologically based individual rates of metal consumption, reflecting the objective state of the processes of production of hot-extruded pipes. |
