Method for producing nickel-based alloy through twenty-roller reversible rolling mill

Abstract

The invention discloses a method for producing nickel-based alloy through a twenty-roller reversible rolling mill. The method is characterized in that the twenty-roller reversible rolling mill is utilized for manufacturing a cold-rolled nickel-based alloy product through coiling-threading-cold rolling and calendaring-annealing-finishing trimming productization, wherein in the cold rolling and calendaring step, the twenty-roller reversible rolling mill is adopted for conducting seven-pass rolling on industrial nickel-based alloy; the reduction rate of each pass is controlled to range from 6% to11%, the rolling force is controlled to range from 200 Ton to 250 Ton, the rolling speed is controlled to range from 100 mpm to 300 mpm, and the tension of each pass is kept constant in the rolling process; and the target thickness is achieved through one rolling process. The method has the beneficial effects that the thickness of a finished product can be obtained through rolling of the single rolling process of the twenty-roller reversible rolling mill, the material model is controlled, the production procedure is shortened, and the production cost of the nickel-based alloy is reduced; andthe production technology condition requirement can be met without modifying single-rack twenty-roller reversible rolling mill equipment, and the equipment utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and relates to a method for cold-rolling nickel-based alloys, in particular to a method for producing nickel-based alloys by using a single-stand twenty-high reversing rolling mill. Background technique [0002] Nickel-based alloys refer to a class of alloys that have comprehensive properties such as high strength and certain oxidation and corrosion resistance at high temperatures of 650-1000 °C. At present, the production of domestic industrial nickel-based alloys mostly adopts the cold rolling mode of reciprocating rolling of a single sheet, which has low output and is prone to rolling defects.
