WITH

This invention relates to the metallurgy of non-ferrous metals and alloys containing copper as the basis, and is intended for them; alloying and deoxidation.

The aim of the invention is to increase the absorption of the composition by reducing the loss of boron and its cheapening.

The content of graphite in the amount of 14-16% and borax 84-86% ensures that the reduction of boron and borax in the copper melt proceeds, the copper melt is saturated with boron, and an inert atmosphere (CO) is created in an open melting furnace.

To determine the optimal amount of graphite and borax, the compositions are prepared by mechanical mixing (see Table 1).

By analogy, a known composition of C + 10% B was tested.

The obtained data on the absorption of boron with different ways of entering it into the copper melt are given in Table 2.

Claims (1)

When using the proposed composition, an increase in the degree of boron uptake by 2-4% is achieved, in addition, the cost is reduced due to the use of expensive amorph instead of expensive. boraxa cheaper boron.
