Abstract

The invention discloses a continuous casting and rolling preparation method of a novel zinc alloy wire. The continuous casting and rolling preparation method comprises the following steps: (1) smelting a Zn-Ce intermediate alloy; (2) zinc alloy smelting; (3) zinc alloy continuous casting; and (4) zinc alloy continuous rolling. Compared with the prior art, the method has the advantages that the zinc-copper-titanium alloy wire for thermal spraying is prepared by adopting a continuous casting and rolling technology, a Zn-Cu-Ti-Ce alloy is prepared in an induction furnace with the capacity of 2 t, a Zn-Cu-Ti-Ce alloy bar with the diameter of 50 mm is formed in a continuous casting machine, the bar is subjected to 14-pass rolling deformation, the alloy wire with the diameter of 3 mm is prepared, and the zinc-copper-titanium alloy wire for thermal spraying is obtained. And the problem of industrialization of the zinc-based copper-titanium alloy wire is solved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for preparing a novel zinc alloy wire by continuous casting and rolling. Background technique [0002] Steel materials are widely used in many aspects of national production and life. However, steel materials will be corroded by chemical or electrochemical reactions with some media in the surrounding environment during long-term service. Corrosion of steel components will not only cause huge economic losses but may also cause major accidents and damage people's lives and property. Safety. In order to reduce the harm of corrosion, various anti-corrosion methods and surface treatment technologies have been developed. Among them, thermal spraying technology is a simple and effective anti-corrosion process for steel materials, which is widely used in electric power, petrochemical, automobile, electrical appliances, construction and other industries. Thermal spray...
