Method for producing nonferrous metal wire rods with different specifications by high-speed wire rod mill

Abstract

The invention provides a method for producing nonferrous metal wire rods with different specifications by a high-speed wire rod mill. The method comprises the following steps that materials are selected; heating is carried out; plain-barreled roll micro-rolling or pre-rough rolling is carried out; rough rolling is carried out; pre-finish rolling is carried out; pre-water-cooling temperature control is carried out; finish rolling is carried out; water-penetrating cooling temperature control is carried out; spinning is carried out; air cooling temperature control is carried out; and packing is carried out, firstly nonferrous metal blanks with different specification lengths are made into square blanks through plain-barreled rolling, then round rod materials are obtained through pre-finish rolling, and finally, the nonferrous metal wire rods with the different specifications are obtained through finish rolling. According to the method for producing the nonferrous metal wire rods with thedifferent specifications by the high-speed wire rod mill, the multiple nonferrous metal blanks with the different specifications are rolled on the high-speed wire rod mill through plain-barreled rollmicro-rolling, the problem of unicity of high-speed wire rod mill hole-type rolled blanks is solved, the collinear production of nonferrous metals such as nickel and titanium or alloy wire rods thereof and steel wire rods is realized, the yield and quality of the nonferrous metal wire rods are greatly improved, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the technical field of nonferrous metal processing, in particular to a method for producing nonferrous metal wires of different specifications by using a high-speed wire rolling mill. Background technique [0002] Wire rods in the iron and steel industry generally adopt fully continuous horizontal and vertical alternating high-speed wire rod rolling mills, with a speed of up to 90m / s, which can realize controlled rolling and controlled cooling, with an annual output of 600,000-700,000 tons. Small, good quality pros. [0003] At present, the production process of non-ferrous metal wire rods at home and abroad mainly adopts transverse rolling mill, double double rolling mill or semi-continuous rolling mill. The output is low, the efficiency of the rolling mill is low, and there are disadvantages such as large head-to-tail temperature difference, poor dimensional accuracy of finished products, and single billet size, so temperatu...
