Nickel-based high-temperature alloy strip refining method

Abstract

The invention discloses a nickel-based high-temperature alloy strip refining method which comprises the following steps: firstly, carrying out electroslag refining on an alloy material smelted by a vacuum induction furnace and producing a steel ingot, then sampling the steel ingot and carrying out chemical analysis to judge whether the steel ingot is qualified or not, then forging the qualified steel ingot and producing a flat blank, then the flat blank is subjected to hot rolling and cold rolling treatment, a finished alloy strip product is obtained, then the finished alloy strip product is detected, and refining of the nickel-based high-temperature alloy strip is completed. The rationality and accuracy in the procedures of electroslag refining, chemical analysis, forging, hot rolling, cold rolling and finished product detection in the whole production process of the nickel-based superalloy are achieved, the product quality of the finished nickel-based superalloy is guaranteed, and the purity and the structure uniformity of the nickel-based superalloy are improved; and the surface and internal quality of the steel ingot is improved, the performance of the nickel-based high-temperature alloy is also improved, and the method has the advantages of being scientific and reasonable, high in applicability, good in effect and the like.

Description

technical field [0001] The invention relates to the technical field of manufacturing nickel-based superalloy strips, in particular to a method for refining nickel-based superalloy strips. Background technique [0002] Nickel-based alloys refer to a class of alloys with comprehensive properties such as high strength and certain oxidation and corrosion resistance at high temperatures of 650-1000 °C; according to the main properties, they are subdivided into nickel-based heat-resistant alloys and nickel-based corrosion-resistant alloys , nickel-based wear-resistant alloys, nickel-based precision alloys and nickel-based shape memory alloys, etc.; superalloys are divided into iron-based superalloys, nickel-based superalloys and cobalt-based superalloys according to different substrates; nickel-based superalloys are referred to as F. [0003] At present, in the production process of nickel-based alloys, the production process is unreasonable, and the lack of timely detection in t...
