Casting Processes| Резюме: | The relevance of the work is determined by the need to clarify and further develop approaches to the formation and calculation of the composition of the charge, which is associated with the expansion of factors that affect the technology of foundry production and which must be taken into account when performing such calculations. The article substantiates approaches to the development of traditional solutions to the problem of forming the composition of the charge for smelting iron, steel, and alloys in connection with the commissioning of modern smelting units and the use of different charge materials than before. Traditional methods of charge calculation using computer technology are analysed. The advantages and disadvantages of classical approaches and methods traditional for foundry production are proved. It is shown that the known methods and computer programs developed for modelling the procedure for selecting the charge and regulating the chemical composition of the melt of iron, steel or alloys in the process of their smelting do not take into account the instability of the chemical composition of the charge components. It is also shown that, according to well-known methods, charge calculations are usually carried out under the assumption that the content of chemical elements in each of its components is equal to their average values from the ranges of values regulated by standards, specifications or other regulatory documents for charge materials. If the charge is formed on the basis of this principle, there is a risk that the range of content of any chemical element in the smelted iron may be wider and go beyond the regulated range in the standard for finished products with all the negative consequences. |
