Product Introduction

Wire rod, widely known as wire or steel wire, is a long steel product that has undergone a special process. From the material point of view, it is usually composed of high-quality carbon structural steel or alloy structural steel. These raw materials are strictly smelted and processed to ensure the high quality of the rod.

The steel wire rod is characterized by its small cross-section size and large length, which makes it easy to bend and wind, and easy to transport and store. At the same time, it also has good mechanical properties and processing properties, such as high strength, high toughness, good weldability and plasticity. These characteristics make it widely used in many fields.

Feature
Production Features
high strength
High Intensity
The wire rod is treated by special technology and has high strength characteristics. This makes it able to maintain good stability and durability when it is subjected to external forces such as pressure and tension. In the field of construction, high-strength wire rods are often used as reinforced concrete skeletons and prestressed components, which can greatly improve the load-bearing capacity and safety of buildings.
ductility
High Toughness
It also has excellent toughness, that is, it can undergo large deformation under the action of external forces and is not easy to break. This performance gives the rod greater flexibility in the manufacture of various mechanical parts and transmissions, and can adapt to complex working environments.
cutting
Good Weldability and Plasticity
Its weldability and plasticity are excellent. This means that it can be easily processed into a variety of shapes and sizes by welding, bending, winding and other processing methods. For example, it can be processed into steel bars, wire ropes, springs, wire mesh, etc., to meet the needs of different fields.
hygiene
Excellent Corrosion Resistance
Its surface is usually specially treated to improve its corrosion and wear resistance. This enables it to maintain good performance in harsh environments such as moisture, acid and alkali. At the same time, the wear resistance also makes the rod not easy to be damaged during long-term use, extending its service life.
Process
Production Process
01
Raw material preparation
The first step in rod production is raw material preparation. The raw materials are usually high-quality iron ore or scrap steel, which need to go through strict screening and pretreatment to ensure that their quality and composition meet the production requirements. In the pre-treatment process, the raw material will go through crushing, screening, magnetic separation and other processes to remove impurities and non-conforming parts.
02
Heat up
The pre-treated material is fed into the furnace for heating. The heating furnace usually uses natural gas, coke and other fuels to heat the raw material to a suitable temperature range through high temperature for subsequent rolling or drawing processes. In the heating process, it is necessary to precisely control the furnace temperature and heating time to avoid product quality problems caused by overheating or underheating of raw materials.
03
Rolling (or drawing)
The heated material goes into the rolling mill or drawing machine for deformation treatment. Rolling process through the extrusion of the roll, the raw material is pressed into a certain cross-section size and shape of the wire. The drawing process is to draw the raw materials into finer and more accurate steel wire products through the drawing effect of the mold. Both processes require precise control of equipment parameters and process conditions to ensure product quality and performance.
04
Cooling
After rolling or drawing, the wire rod goes into the cooling unit for rapid cooling. The purpose of cooling is to eliminate the thermal stress and residual stress generated during the deformation process of the wire, while improving the hardness and strength of the wire. The cooling method can be water-cooled, air-cooled or air-cooled, depending on the material and specifications of the product.
05
Recoiling
The cooled wire is fed into the recoiling machine for winding. The machine tightly winds the wire through a rotating drum to form a steel wire. During the winding process, the speed and tension of the drum need to be precisely controlled to ensure the winding quality and appearance of the product.
