The steel wire rod is a metal product which is obtained through a hot lamination process thanks to a specially designed train for this effect, known as steel mills, the wire rod is circular or oval section that varies between 5 and 30 mm outside diameter, which is usually rolled into coils of hundreds of meters, you can say that the applications of this steel products are varied but can usually be defined as follows: spring steel. – R To be useful for this application, the required steel wire rod should have a high yield, besides the absence of surface defects that can cause the onset of a fracture. Steel for machining. – They are used for the manufacture of parts and mechanical parts by metal removal processes, to achieve good mechanical property associated with this type of process the wire rod has lead, sulfur or bismuth. High carbon steel.
– It is used to make twisted wire cables, pre and post-tensioning for construction industry. Low Carbon Steel. – Very useful for its malleability and are used for the manufacture of many pieces, such as staples, clips or tie wires called widely used in our environment in the construction industry was the origin of the casting process and subsequently to the billet formed there, which is preheated in a furnace, usually a gas, which then heats it is passed by several rollers rotate in opposite directions and that apart from this condition rotation exert pressure perpendicular to the axis of wire rod up obtain their final shape and size, when the lower section to be obtained the greater the number of cylinders required, it is important to note also that this process of forming it done with hot metal, in order to diminish the efforts and mechanical energy required to conform, but its temperature is carefully controlled because excessive heat determine adherence to the rollers and an eventual deterioration of the same, usually these rolls are made in alloy steel with nickel and molybdenum and chromium are formed by casting, as is evident, are usually properly cooled inside. Besides the need described above is formed to control the cooling conditions for the steel wire is malleable and that rapid cooling can result in irregular hardening resulting in fragility of the product. The composition of the steel wire may vary depending on the application and the process used but is very common to find it with carbon contents of about 0.
8%, proportions of other elements such as phosphorus from 0. 48% Manganese 0. 30% including that of Steel To have adequate mechanical properties requires a current of air during the lamination process, note that the steel wire rod should enter the lamination process at a temperature of about 1000 C to finish a temperature similar to that of the environment.
