- the availability of the alloy is divided into the results of an analysis-analysis of the contents of the main components of the alloy and - 5 - of impurities, after the last handing over is poured into the molds
- the following are examples of its completeness.
- a total of 2950 kg of electrical equipment is loaded due to the loss of heat.
- the PLC fills 22050 kg of liquid aluminum with a temperature of 820 ° C.
- the calculated value of the brown alloy in the alloy is II, 7, ALC. Dal ⁇ has the effect of stirring the resulting aluminum-dispersed alloy with the resultant dissolution.
- the appliance the speed of the appliance, the direct contact with the appliance and the direct loss of the material, which absorbs aluminum, fuses it and fuses it, which fuses and absorbs aluminum, which absorbs and absorbs aluminum.
- the efficiency of the offer was largely due to the results of the anaize of the alloy for the content of water and aluminum oxide, as well as the waste. For comparison, for the same indicators, the effectiveness of the known methods was evaluated.
- the proposed invention can be used in the territory of the territory of the Republic of Ukraine for the removal of metal and melting equipment.
- the indicated alloy can be used for making custom cast iron for the needs of automobile, automotive and industrial applications.

For example, in the case of a household furnace with a capacity of 25,000 kg of liquid metal, a total of 2950 kg of electrical equipment is loaded due to the loss of heat. Then, in the bathtub, the PLC fills 22050 kg of liquid aluminum with a temperature of 820 ° C. The calculated value of the brown alloy in the alloy is II, 7, ALC. Dalββ has the effect of stirring the resulting aluminum-dispersed alloy with the resultant dissolution. There is a direct disruption of the alloy, an increased electrical impairment of the device, and an increase in the load on the basis of the voltage, is a result of a negligible However, since the beginning of the mixing of the temperature in the bath, the temperature is reduced to 700 ° C by eliminating the need for reducing the temperature and eliminating the need for
