The bar after leaving the last rolling mill stand is fed to quenching box at a very high speed. In this section, a rapid and controlled water quenching is performed reducing the temperature of surface drastically from around 950°C to 600°C. Due to higher speed, only outer portion of bar gets quenched. The inner part remains hot only. The case due to rapid quenching gets converted in

slabs, plates, sheets or Structural components. The same is shown in the flow chart. Classification of Rolling Process Rolling Process can be classified either i)based on the temperature of the metal during rolling or ii) based on the arrangement of the rolls and their number or iii)based on the Products rolled. i)based on the temperature: Rolling can be classified as Hot Rolling or Cold ...
Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel (I-beams, angle stock, channel stock, and so on), bar stock, and rails.
Cold-Rolled Steel Sheets and Coils are extensively used as basic materials in automobiles, electrical appliances, steel office equipment, various types of containers, and numerous other products closely connected to our daily lives.

The Pickled coils are cold rolled on 4 Hi AGC cold rolling mill to obtain the required thickness and annealed in HSD fired bell-type annealing furnace for bright annealing. In case of medium and high carbon coils, the process of rolling and intermediate annealing can be repeated to a number of times depending upon the final thickness to be obtained. These coils after final rolling are slitted ...
There is almost no end to the uses of high-grade steel strip in today's world. They include everything from aircraft to beverage cans. That explains why we design our cold rolling mills to be just as versatile.

Cold Rolling Flow - Primetals Technologies Japan, Ltd.
Cold Rolling Flow At the pickling process, the oxidized scale is removed from the surface of the hot coils that were produced by the hot rolling mill. Following the pickling process, the coils are then sent to the cold rolling process, where they are rolled still thinner at cold (room temperature) conditions until they reach the thickness required for their final applications.
The ZR mill is a mill for the cold rolling of hot-rolled coils of stainless steel and other hard materials to the designated product thickness and strip shape accuracy. The ultra-small diameter rolls are firmly supported in a 20Hi roll cluster arrangement.
