Description

Table 1

deoxidizing elements in the alloy should not exceed 2% titanium, 1% manganese and 1% silicon.

The chemical composition of the silicas treated with the proposed ligature is given in table. one.

When using the proposed ligature, the alloy is alloyed with residual content of deoxidizing elements. When smelting alloys in an open induction furnace, a ligature is introduced into the furnace before the metal is poured into the ladle, the metal is poured into rod forms. The weight of each heat is 5 kg.

The compositions of the proposed ligatures and properties of the obtained magnets are given in table. 2

The alloys, molded using the proposed ligature, have high magnetic characteristics.

Properties of alloy made using ligatures

Famous

The magnetic treatment of magnets with a 15-24% cobalt content, obtained using the proposed ligature, is simplified. In magnetic alloys, due to the stabilization of the solid solution, the heating temperature for quenching decreases from 1250–1300 ° C to 900 ° C.

The magnetic properties of alloys treated with proposed and known master alloys are listed in Table. 3

Thus, when using the proposed master alloy, the purity of the alloy increases in oxygen and, therefore, in non-metallic inclusions, i.e. the oxygen content decreases 1.5 times; magnetic properties are improved: residual induction, Br, increases from 7,500 to 9,000-10,000 Gs; magnetTable 2
