Wire Rods and Wire Rod Mills...

Wire Rods and Wire Rod Mills Steel wire rods are an all-round talent since they are the key product of steel industry with multiple uses. They are used as the material for fasteners, springs, bearings, wire ropes, chains, cables, wire meshes, wire fencings, tyre cord, reinforcement in railway sleepers, and many other uses. They are used for the components needed for the automotive industry, chemical industry, power stations and machine engineering. Unlike cold-rolled sheets, heavy plates, pipes, sections and other steel products, wire rods are seldom used as hot rolled for final products, but they are manufactured into machine parts after undergoing one or more stages of so called post-processing such as heat treatment, forging and wire drawing at specialist plants. Wire rods are generally drawn down to a specific diameter before being subjected to forging or other forming operations in secondary processing. In many cases, the size of the wire rods before being subjected to these forming operations is to be less than the minimum size of 5.5 mm that can be supplied as rolled. Generally each of the wire rod product is developed with due attention to its behaviour at the post-processing stages. What is required for a steel plant regarding wire rods is good processibility and fulfilment of the required properties after the processing. Furthermore, since the costs of the post-processing is sometimes several times the price of the wire rods, it is increasingly important to reduce the total integrated manufacturing cost from the steel material to the final product. Also thermo mechanically treated (TMT) reinforcement bars of 6 mm, 8mm and 10 mm basically required for the building construction are produced in the wire rod mills. The following generally characterizes the wire rod products. Product grades are widely varied from...
