  • Manufacturing Process

The high-speed wire rod mill of Baosteel Branch (the largest branch of Baosteel Co., Ltd) began production in March 1 and rolls plain rod from .0mm to 2 mm with production capacity of up to 70,000 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. Refining 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 200 , 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 finishing 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 finished 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.
