Introduction to Wire Rod

宝钢 股 份 宝钢 分 公 司高 速 线 材轧

机于1999年3月 投产，目前年生产 量约
57万 吨 。 产 品规ø5.0-ø26.0mm。 主

要品 种 有帘 线 钢、 弹 簧 钢 、 冷 镦 钢、

桥梁 缆 索用 镀 锌钢 丝 、 高 碳 钢 和 焊接

用钢等。

线 材 原 料 采 用 高 炉 铁 水 和 优 质

废钢 ， 经过 转 炉或 电 炉 及 精 炼 工 序的

纯 净 钢 冶 炼 技 术 生 产 ， 确 保 钢 质 纯

净。 钢 坯精 整 线对 钢 坯 表 面 存 在 缺陷

进行 清 理， 确 保钢 坯 表 面 质 量 。 随着

2008年5月电炉大方坯连铸投产，线材

原料 水 平得 到 大幅 度 改 善 ， 将 进 一步

提升线材实物质量。

线材 生 产 线的 主 要 设备 从 美 国摩

根公司引进，单线无扭连续生产，最大
轧制 速 度 为 120m/s。 采 用 控 制轧制和

控制冷却工艺，通过对冷却水箱水量和

斯太尔摩线冷却速度的控制可获得产品

所期 望 的组 织 和性 能 。 为 保 证 产 品表

面质量和尺寸精度，在精轧机组和减定

径机组后分别设置了影像探伤仪和测径

仪，产品尺寸精度可达 0.1mm。

宝钢 分 公 司质 量 管 理采 用 一 贯质

量管理方式，对产品系列从原料入厂直

至产品出厂进行以质量为中心的全过程

最优化控制，并借助先进的质量控制方

法不断改进产品质量。

宝 钢 分 公 司 生 产 的 汽 车 用 帘 线

钢、弹簧钢、冷镦钢以及桥梁缆索用镀

锌钢丝在国内知名企业和重大工程中广

泛获得应用，多次获得上海市和国家科

技进步奖。

The high-speed wire rod mill of Baosteel
Branch (the largest branch of Baosteel
Co., Ltd) began production in March 1999
and rolls plain rod from 5.0mm to 26mm
with production capacity of up to 570,000
tonnes per year. The major products in­volve wire rod for tire cord, spring steel
wire rod, steel wire rod for cold heading
and cold forging, galvanized wire for bridge
cables, high carbon steel wire rod, wire rod
for welding, etc.
Raw materials for wire rod include blast
furnace hot metal and high quality scraps.
Rening processes after BOF or EAF en­sures the cleanliness of steel. The flaws
are cleaned up on the billet conditioning
line in order to obtain high surface quality.

With the commissioning of new continuous
bloom casting process in May 2008, the
practical quality could be further upgraded
due to the great improvement of the raw
materials for wire rod.
The main rolling equipments of mill are
supplied by Morgan Construction Compa­ny and the rolling line is single-strand with
maximum nishing speed of 120 meters
per second. Perfect microstructures and
mechanic properties are gained through
controlling water boxes and Stelmor Cool­ing System. In order to ensure accurate
diameter with a tolerance of +/-0.1mm and
high surface quality, one HotEye flaw de­tector and two ORBIS diameter gauges
are located after the No-Twist Finishing

Mill and Reducing/Sizing Mill.
Integrating Quality Control is applied
throughout the entire manufacturing pro­cesses from the handling of raw materials
to the delivery of nished products to guar­antee full customer satisfaction. At each
stage of production from steelmaking to
rolling of wire rod, improvements of prod­uct quality are ensured.
Top quailty wire rod products manufactured
are put into use widely in many well-known
domestic enterprises and local key proj­ects. These products have also won lots of
honors in Shanghai as well as numerous
national science and technology progress
awards were given to the company in hon­or of these products.
