Cold rolled steel coils have become the preferred option for manufacturing companies, engineering firms, product designers, and various industry experts involved with the production of durable goods.
Manufacturers can turn these coils into appliances used in residential and commercial kitchens, automobile parts and components, and even various construction materials. A broad range of products gets made with coils, including frying pans, vehicle exhaust pipes, metal desks, and computer cabinets.
The Cold Rolling Process
To understand the growing demand for cold rolled steel coils, consider the process. With cold rolling, the treatment of steel is below its recrystallization temperature, meaning it is at or below room temperature. As a result, the material’s thickness compresses, enhancing the tolerance level. Ultimately, this yields a higher tensile strength in the finished product by up to 20 percent.
Also, hardening the metal’s inner strains creates a smoother finish. While some people still prefer the hot rolled method of making steel coils, the sleek and modern look of the finish gives the cold rolled process a considerable advantage. With an improved surface finish, parts and components are aesthetically pleasing, making them ideal for furniture, automobile components, and more.
As imagined, the quality of the material used to create cold rolled steel coils has a significant impact on the finished product. For that reason, top-rated mills follow best practices to continuously check the material quality as it moves down the picking line. That way, they can ensure that the surface of the material is immaculate before going through the cold rolling process. The outcome is a stronger and more durable product with a superior surface finish.
Annealing is the other part of the process of making cold rolled steel coils. With this step, the coils become extra workable. The metal gets heated above its recrystallization temperature, or above room temperature, and then cooled back down. What happens is that the steel’s microstructure resettles, thereby improving its mechanical properties.
Annealing also eliminates the buildup of internal stresses that occur while the steel goes through the cold rolling process. That makes it possible for reputable mills to offer fully customizable coils, making them easier to handle while meeting exact project specifications. With annealing complete, the metal goes through another process to enhance its elasticity and toughness.
The tempering step of producing cold rolled steel coils consists of putting slight pressure on the material. Once the metal flattens, the mill can apply a premium surface finish. Not only will the coils look more aesthetically pleasing, this also helps avoid any stretcher strains that can occur during the forming and deep drawing phase.
