Improvement of Productivity and Quality with Cold Drawn Steel Bars
Cold drawn steel bars have been used for many years in manufacturing, providing many benefits in productivity and quality for different products. The process involves the pushing of a bar of heated steel in a die and undergoing a reduction in size and a modification in shape. This process offers a range of benefits from better surface finish, improved machinability and improved strength to better dimensional control and elongated life of tools.
Cold drawn steel bars have become increasingly popular for a variety of manufacturing operations due to their many advantages. The main advantage offered by cold drawn steel bars is improved machinability, which is achieved through a decrease in width and diameter. This leads to a decrease in cutting forces being applied to the steel bar and a reduction in the amount of heat developed during the cutting process. The decrease in heat also helps to reduce the risk of deformation of the steel bar and increases productivity.
Another advantage of cold drawn steel bars is improved strength, which is achieved through an increase in the tensile strength of the steel bars. This is achieved by subjecting the steel bars to multiple heat treatments throughout the manufacturing process. During the heat treatments, the steel bar is subjected to temperatures ranging from 400-600°C. This process allows the steel bar to become stronger and less susceptible to damage.
In addition, cold drawn steel bars offer improved surface finish. As the steel bar is subjected to multiple heat treatments, the surface finish is improved and the surface becomes smoother. This results in a better final product with fewer imperfections in the surface. The end result is a product of better quality that is more attractive and has a longer life.
Finally, cold drawn steel bars also offer improved dimensional control. Since the steel bar undergoes multiple reductions in size and shape during the drawing process, the dimensions of the steel bar can be tightly controlled. This allows manufacturers to produce a more precisely sized bar and also a bar with consistent dimensions. This leads to improved efficiency in production and reduced need for rework and costly material waste.
Cold drawn steel bars have many advantages over other types of steel bars. They offer improved machinability, improved strength, better surface finish and improved dimensional control, all of which can lead to improved productivity and quality in many different manufacturing processes.
