Cold Rolled Steel
Hot Rolled Steel is put through a range of further processing to get Cold Rolled Steel.
The Hot Rolled Coils goes through the process of pickling before being fed into the Tandem Cold Rolling Mill. The output from the Tandem Mill is first cooled at room temperature and then goes through the process of Electrolytic Cleaning before being subjected to Batch Annealing in the furnace. The coils are further passed through the Skin Pass Mill before we get the final product i.e. Cold Rolled Closed Annealed (CRCA) coils.
This results in steel that is superior in terms of dimensional tolerances and offers a wider range of surface finishes.
Country Of Origin : India
Advantages
Advantages of Cold Rolled Steel Coils & Sheets include -
Superior Surface finish - Ensures superior surface cleanliness. This minimises pre-treatment time significantly. It also reduces the chemical consumption in pre-treatment process resulting in cost savings at the customer's end. The excellent surface texture also facilitates paint adhesion.
Uniform Mechanical Properties - Uniform mechanical properties are assured throughout the length of coil. Hence, customers get consistent quality with higher yields during stamping.
Enhanced Flatness - Improved flatness reduces adjustment time and increases productivity.
Higher dimensional tolerances - This reduces wastage and maximizes yield.
Better Weldability - Optimum chemistry of steel keeps electrode consumption to a minimum.

Cold Rolled Steel is a highly versatile product, refined through stringent processing techniques to guarantee outstanding performance and impeccable surface quality. This steel is derived from Hot Rolled Steel which undergoes additional processing to be transformed into Cold Rolled Steel. This process enhances its dimensional accuracy and surface finish, making it suitable for a variety of applications that demand precision and reliability.
The transformation from Hot Rolled Steel to Cold Rolled Steel involves several meticulous steps to ensure the highest quality product:
Pickling: The Hot Rolled Coils undergo pickling to remove oxide layers and surface impurities, preparing them for cold rolling.
Tandem Cold Rolling Mill: The pickled coils are fed into the Tandem Cold Rolling Mill, where they are cold-reduced in thickness through a series of rolling stands.
Cooling: Post rolling, the steel is cooled at room temperature, removing any residual heat from the rolling process.
Electrolytic Cleaning: The steel is subjected to Electrolytic Cleaning to ensure surface purity by removing remnants of rolling lubricants, iron fines, and other contaminants.
Batch Annealing: The cleaned steel is annealed in a controlled furnace environment to enhance its ductility, making it workable for various manufacturing applications.
Skin Pass Mill: Finally, the material passes through a Skin Pass Mill to improve its surface finish and to impart the necessary mechanical properties, resulting in Cold Rolled Closed Annealed (CRCA) coils.
This multi-step process yields a product with superior surface and mechanical properties, specifically tailored for high-performance applications.
Cold Rolled Steel Coils and Sheets offer a host of advantages:
Superior Surface Finish: Ensures superior surface cleanliness, reducing pre-treatment time and chemical consumption, thus delivering cost savings. The excellent surface texture significantly facilitates paint adhesion.
