Uses classify Rod coil into six kinds:
Low Carbon Steel usually produces Wire Rod, which shrinks billet’s diameter dimensions from 5.5mm – 19mm to the desired dimensions with the cold-drawing process, and coated zinc plated to control corrosion. The known use of wire rods is to build the nail, wire-netting, barbed wire, wire mesh, and so onwards.
B. Welding Wire
After cold-drawing, a wire rod can create as a welding wire. There are two types of welding wires; one is inert metal gas (MIG) welding, the additional is coated electrode. Welding wire’s belongings are highly chemical mixing and sulphur range less than 0.023%.
Many fasteners, such as nuts, screws, bolts, nails, anchor bolts, thread rods and sockets, are extremely connected to many industries, particularly automobiles, appliances, commercial structures. Fasteners are created from high-stress wire, high price, and Carbon range less than 0.5%. There are three stages in manufacturing Fasteners: heading, thread rolling, and zinc plating.
D. Construction Industry
High Carbon Steel Coils are widely utilized by rod coil manufacturers in industrial goals, such as :
(A) Prestressed Concrete Steel Wire (PC Steel Wire) for strengthened concrete structures
(B) PC strand wire for extensive, high-quality structure
(C) Wire rope for cable benefit
High Carbon Steel wire rods are likewise utilized in springs, such as
(A) Hard-drawn Steel Wire & Oil Tempered Steel Wire for motorized springs
(B) Oil Tempered Piano Wire for Valve spring and Oil Tempered Piano Wire
F. Automobile Industry
For reinforced tires to use, the wire rod should mark as a wire that contains a small diameter between 0.15mm – 0.38mm and has the belonging of high tension & high power to face any non – destructive production procedure.
The manufacturing process of the wire rod uses billet as the bottom material through Five stages billet conditioning, reheating, rolling, cooling and inspection.
This process is planned to check the surface quality of the billet, removing any defects. Shot blast utilizes to release any scale from the cover. Magnet particle testing and optical inspection are used to determine faults that must extract using a grinder. Ultrasonic testing, measurement, and geometry checking are part of the internal rate verification process.
The temperature within the furnace and the reheating period rely on utilizing the outcome. To remove decarburization, which can affect the base quality of the product, a billet is pre-heated enough at a low temperature before being rumbled within the reheating furnace. For this objective, the fuel and air ratio is controlled precisely.
The temperature, draft, and deformation velocity with which the outcome roll maintains to meet material components’ consumer requirements. Further steps to secure the surface quality include adjusting roll roughness and gap, detecting any damages, and dimension modification.
The cooling temperature at the laying charge, the airflow and motion speed of the blower on the cooling mattresses, and the insulation cover’s cooling speed control ensure that the product has the characteristics needed per application. High carbon steel wire shafts allow rapid cooling to reach the microstructure needed for successful drawing. In contrast, low carbon steel is subject to gradually cooling to assure that the outcome provides the softness needed for the customer to eradicate an annealing procedure.
Samples are carried from the front and rear boundaries of creation behind rolling and cooling for testing to determine any weaknesses in dimension or texture or material goodness. Packaging and tagging are also examined according to consumer requirements before ship.
