Continuous-casting and continuous-drawing processing technique of N6 nickel alloy wire

Abstract

The invention relates to a continuous-casting and continuous-drawing processing technique of an N6 nickel alloy wire. The continuous-casting and continuous-drawing processing technique is characterized by comprising the following steps: during smelting and drawing, charging nitrogen into an upper space of melted metal; putting an electrolytic nickel plate and N6 alloy leftovers together into an intermediate-frequency smelting furnace; simultaneously adding graphite carbon of which the weight is 0.1 percent of the weight of the electrolytic nickel plate; controlling the temperature to be 1470+ / -20 DEG C to melt the metal; adding NiMg alloy according to a proportion of 0.4Kg / 100Kg for degassing; keeping the temperature; starting continuous-casting of a lead wire; regulating the ratio of pulse rotation length to stagnation distance to be 7:3 and regulating the drawing speed to be 2m / min to 5m / min; synchronously adding cooling water of which the pressure is 0.08Mpa to 0.12MPa. The continuous-casting and continuous-drawing processing technique of the N6 nickel alloy wire has the beneficial effects of reducing a plurality of processing steps such as peeling of a blank material, hot-rolling blooming and primary draw-molding of a wire ingot, prolonging the processing period of the wire and improving the comprehensive rate of finished products, and also lowering the processing cost of the wire.

Description

technical field [0001] The invention belongs to the processing of alloy wire rods, in particular to a continuous casting and drawing processing technology of N6 nickel alloy wire rods. Background technique [0002] At present, the processing of nickel and nickel alloy wire rods has been smelting and casting, billet peeling, hot rolling billet, repeated multi-pass wire drawing and process heat treatment annealing. The process is characterized by many processing steps, long processing cycle, and low comprehensive yield of products processed at the same time. Nickel alloy metal has high strength, high plasticity, and is very easy to absorb hydroxide ions. It is prone to fracture in the later drawing process, so the processing cost of nickel alloy wire is very high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned technologies, aiming at the technical problems that the nickel alloy metal has high st...
