Abstract

The invention discloses a method for forging large-scale Nb47Ti alloy rods for superconducting wires. Cooling; the Nb47Ti alloy ingot after forging is carried out for the second fire forging, the second fire forging process includes elongation, rounding, and cooling after forging; the Nb47Ti alloy ingot after the middle forging is forged by diameter Machine for the third fire forging, cooling after forging, to obtain Nb47Ti alloy large-size rods. By selecting the deformation method, deformation equipment and deformation amount, the forging fire times and production cycle are shortened, thereby reducing the cost, and large-scale Nb47Ti alloy large-scale rods with uniform and fuzzy structures at low magnifications and fine and uniform structures at high magnifications can be obtained.

Description

A kind of forging method of Nb47Ti alloy large-sized bar for superconducting wire technical field The invention belongs to non-ferrous metal processing method technical field, relate to a kind of Nb47Ti alloy large size for superconducting wire rod Bar forging method. Background technique Nb47Ti alloy rod is an important raw material for preparing superconducting wire, because the extremely harsh use of superconducting wire Therefore, high requirements are placed on the uniformity of the structure of the Nb47Ti alloy rod. Forging of traditional Nb47Ti alloy bars The ingot is sawed and cut, and after heating, the ingot is subjected to upsetting deformation for multiple fires, so as to improve the billet group. For the purpose of weaving uniformity, due to the more forging times and the longer production cycle, the production cost also increases. SUMMARY OF THE INVENTION The object of the present invention is to provide a kind of forging method of Nb47Ti alloy lar...
