Problems solved by technology

The cracks formed after these non-metallic inclusions are broken disperse the damage propagation path when scraping cotton, increase the loss of steel wool in the cutting area of ​​scraping cotton, cause the problem of slag falling, and cannot meet the length requirements of fibers, making production difficult and cotton output The rate is low and cannot meet the requirements of cleaning supplies

Abstract

The invention discloses a steel wire rod with a length of greater than or equal to 500 mm used for long-fibered steel wools, which comprises the following components in percentage by weight: 0.06-0.10% of C, 0.085-0.24% of Si, 0.85-1.20% of Mn, less than or equal to 0.020% of P, less than or equal to 0.020 % of S, less than or equal to 0.01% of O [T], and less than or equal to 0.005% of Als. The production method comprises the following steps: carrying out molten iron desulphurization and converter melting; conventionally carrying out ladle argon blowing and pre-deoxidation for slag making; carrying out refining in a LF furnace; carrying out continuous casting on the obtained objects so as to obtain blanks; conventionally heating the blanks and carrying out high-speed wire rod rolling; and carrying out conventional delayed cooling on the obtained product and collecting coils for standby. The length of fibers produced by using the method disclosed by the invention is not less than 500 mm, and thinner, the tensile strength of the steel wire rod is not more than 420 MPa, the percentage reduction of area is not less than 70%, and the steel wire rod is soft in handfeel, and no slag drops. The steel wire rod is applicable to the polishing of stone materials and ceramic tiles and the burnishing and cleaning of various high-grade furniture, and extremely easy to degrade; and because the main composition is iron, the steel wire rod after degraded does not pollute the environment.

Description

technical field [0001] The invention relates to wire rod steel and a production method thereof, in particular to wire rod steel for preparing long-fiber cotton steel and a production method thereof. Background technique [0002] Steel wool is a new type of anti-friction material, with an average diameter of 10-60 μm and steel fibers with an indeterminate cross-section. It is in the form of cotton wool after collection. It is mainly used in the manufacture of automobile clutches and brake pads. It has better manufacturing properties than asbestos. Dynamic performance, long life, no pollution, the product has been widely used at home and abroad. At present, the raw material used to produce short-fiber steel wool, that is, steel wool steel wire rod technology has matured, and domestic iron and steel companies such as Wuhan Iron and Steel, Shagang, and Shougang have produced it for the production of short fibers for brake pads. With the development of society and the improvemen...
