HCL Continuous Pickling Line with a capacity of 1.4 Mtpa uses proven and reliable technology to process hot rolled carbon steel as per the technical specifications.

Pickled coils are rolled in twin stand cold rolling mill where they are processed into a specified thickness. Generally, the rolling reduction ratio is 50% to 90%. The critical point at this stage of the process is to maintain uniform and precise flatness throughout the entire length of the coil.

After cold rolling, the steel strip is hard and brittle with its grains elongated in the rolling direction. To obtain the desired grain structure and to improve the mechanical properties, the strip is annealed at an elevated temperature in a reducing atmosphere.

Every aspect of SunRax PLTCM is designed to add precision and quality control to the cold rolled process. In this, pickling line is linked with cold rolling mill, which provides better shape control, delivers significant improvements with regard to mill productivity, yield, and production as a result of the elimination of strip threading and tailing-out operations.

The continuous annealing line is design to produce material for automotive industry, appliance industry etc. In order to get uniform mechanical properties, it has a radiant tube heating type vertical annealing furnace followed by the rapid cooling type cooling furnace and over aging section.
