- This method does not allow the manufacture of a bimetallic compound, for example, such as metal, because steel-copper is for the following reasons:
- a transitional zone commensurate with the dimensions of the bimetallic compound, is used; At the same time, the presence of a transitional zone of any size in a significant deteriorates the quality of the connection of the layers.
- the known method does not ensure a high quality connection of the layers in a bimetallic product, since the unchanged nature of the change in the power of the elec- tric
- the method does not provide for the economic consumption of defective non-ferrous metals.
- the products received are not very durable and, therefore, do not have the required operating speed.
- recesses of the rotational sleeve may be performed to increase the total separation of the two-way connection of the product.
- the productive element is desirable to be cooled. 10 It is wise to store the cooler in a safe place and install the food in the consumable part. 15

- Fig. 8 is a bimetallic product obtained by the proposed method according to the invention.
- the first outer layer is formed from the steel of the sleeve I, and the second inner layer is the copper one, which is encrusted with the metal used; it is elec- trode 3.
- the temperature of the capture does not combine the two metals in the bimetal due to the hardening of the metal 3 and the immunity of I.
- the lower part of the sleeve I can be heated by any known material before starting the electrical discharge.
- the temperature _ heating system is 1.0-1.2 slag melting temperature. ⁇ a ⁇ ime ⁇ l ⁇ i li ⁇ e bime ⁇ alliches ⁇ g ⁇ s ⁇ edineniya "s ⁇ al-copper" ⁇ ime- nyayu ⁇ shla ⁇ , imeschy ⁇ em ⁇ e ⁇ a ⁇ u ⁇ u ⁇ h ⁇ lavleniya, ⁇ avnuyu
- the heating of the sleeve I is selected from the range of 800-960 ° ⁇ .
- the pre-heating of the sleeve I ensures a high quality connection of the layers in the bimetal and, as a result, an increase in the yield of the annual metal.
- the recesses 7 are irreplaceable. A significant increase in the surface area significantly improves the diffusion of the metal
- the elements 9 are accommodated in accordance with the required property of the household - 6 -

- Element 9 is heated after the end of the electric waste by any known means, which makes it easier to 10 to read the conditions for removing it from the product. This is necessary due to the fact that in the process of molding, the element 9 is compressed and jammed as a result of thermal shrinkage due to the internal wiring is not ensured. This increases the reliability of castings. 15 In FIG. 4, there is one more version of the implementation of the technical-logical circuit for casting full bimetallic products - • .
