Abstract

The invention belongs to the field of metal materials, and specifically discloses a steel wire rod for aluminum-containing steel fibers and used for deep drawing, and a rolling method thereof. A continuous casting billet comprising specific components is obtained according to an aluminum-containing pure steel smelting process, reasonable heating temperature and heating time of the continuous casting billet are controlled in a heating furnace, and the process parameters of the wire rod in a rolling process and the cooling process parameters of the wire rod on a Stelmor cooling line are optimized, so that the produced wire rod for the steel fibers is high in universality, uniform in structure, small in crystal grain, excellent in mechanical property, and good in plasticity index, and an ironoxide sheet has a thickness of 10-20[mu]m, and is suitable for mechanical shelling and low in wire fracture; and the wire rod produced by the method has tensile strength Rm of 350-390MPa, percentageelongation A of not less than 40% after fracture, area reduction Z of not less than 80%, and ferrite grain size of 7-8, the wire fracture in a drawing process of a user can be controlled to be less than 0.25 times per ton, and the technical requirement of a wire rod for high-grade steel fibers is completely met.

Description

technical field

[0001] The invention belongs to the field of metal material production, and in particular relates to a steel wire rod for deep drawing aluminum-containing steel fibers and a rolling method thereof. Background technique

[0002] Aluminum-containing steel fiber steel is mainly used to make steel fiber. Steel fiber is a new type of high-performance building material with high tensile strength, uniform dispersion, no agglomeration, and good bonding performance with concrete. Features, mainly used in the manufacture of steel fiber reinforced concrete. Compared with ordinary concrete, the strength, tensile and bending resistance, toughness, impact resistance, service life and other properties of steel fiber reinforced concrete are greatly improved, thus replacing the threaded steel skeleton. It is called the third-generation concrete, which is convenient for construction and can be It greatly simplifies preparation work and labor force, increases structural safety...
