CR Coils

Cold Rolled Steel Coils

Cold Rolled Steel Coils

These coils and sheets are primarily used in the automobile industry.

  • Cold-rolled coils have more accurate dimensional tolerances, better surface quality, and improved mechanical properties compared to hot-rolled coils.
  • The cold-rolling process involves passing hot-rolled steel through rollers at room temperature, shaping it into thinner and more precise coils.
  • Cold-rolled steel coils are used in various industries due to their superior properties and versatility.
  • They are also known as CRCA coils (Cold Rolled Closed Annealed coils) and are widely used in manufacturing and construction.
Key Advantages

Superior Surface Finish

The surface is clean, which minimizes pre-treatment time and reduces chemical consumption during pre-treatment.

Uniform Mechanical Properties

Consistent quality with higher yields during stamping.

Enhanced Flatness

Improved flatness reduces adjustment time and increases productivity.

Higher Dimensional Tolerances

Reduces wastage and maximizes yield.

Better Weldability

Optimum steel chemistry minimizes electrode consumption.

The Steps

Transforming Hot-Rolled Steel into Cold-Rolled Perfection

The process involves taking hot-rolled steel and subjecting it to further processing to achieve cold-rolled steel. Here are the steps:

01

Pickling

The hot-rolled coils undergo pickling to remove impurities.

02

Tandem Cold Rolling Mill

The pickled coils are fed into the tandem cold rolling mill.

03

Electrolytic Cleaning

The output from the tandem mill is cooled and then subjected to electrolytic cleaning.

04

Batch Annealing

The coils are annealed in a furnace.

05

Skin Pass Mill

The final product obtained is Cold Rolled Closed Annealed (CRCA) coils.
