“…This paper proposes a fairly simple way to solve the problem that does not require capital expenditures. It consists in the introduction of high-temperature technology for smelting synthetic iron at 1500-1600 ° C [9]. This technology presupposes the use of up to 70-90% of steel scrap in the metal filling station, that is, to switch to the smelting of pig iron from a charge entirely consisting of steel scrap.…”

The main factor that determines the content of the development strategies of a modern foundry is the use of modern technological processes, especially melting technology. First of all, this applies to the production of iron castings, which make up 65% of the mass of all alloys. Since 2000, in Russia, there has been a sharp decrease in the amount of pig iron scrap, the cost of foundry and pig iron and the cost of their transportation have increased significantly. This led to an increase in material costs in the production of castings from synthetic iron, which was mainly obtained in crucible induction furnaces of industrial frequency (ICT). In addition, problems began to arise with the use of acidic lining as the cheapest and most durable, since an increased amount of steel scrap began to be used in the metal charge, and for this reason the melting temperature was raised above 1450 ° C. The durability of the lining has sharply decreased, and downtime associated with its replacement has increased. All this had a negative impact on the efficiency of the production of synthetic iron castings.

“…An increase in the number of relining leads not only to an increase in downtime and material costs, but also to an increase in energy consumption spent on drying quartzite [7,8]. All this reduces production efficiency and affects competitiveness, since the market requires not only high-quality but also attractively priced castings [9,10].…”

Modernization of physical and mechanical properties of casting alloys, through the introduction of new processes, which can be used to obtain a precise casting with a smooth surface, which does not require machining, with a constant increase in the productivity of the implemented processes, is changing the technological and economic profile of modern foundry. The most advanced equipment is the induction crucible, melting furnace, which belongs to the main production assets and has a direct impact on productivity and, consequently, on profitability. For this reason, it is the main factor determining the content of the development strategies of the enterprise as a whole. Since 2000, iron scrap has been gone, due to the active sale of it abroad, the cost of pig iron and foundry has increased dramatically, in addition, the cost of their delivery increased. This led to higher prices in the production of castings made of synthetic iron, due to the increase in the cost of batch materials. In addition, there were problems with the use of acidic lining, as the cheapest and having a high resistance, as a part of the metal began to use an increased amount of scrap steel and, for this reason, to raise the melting temperature above 1450 Celsius. For this reason, the efficiency of production must be paid great attention.
