Cold rolling is a process which passes metal through rollers at temperatures below its recrystallization temperatures. This increases the yield strength and hardness of the metal. This is done by introducing defects into the crystal structure of the metal creating a hardened microstructure which prevents further slip.
Cold-rolling mills can produce various products like the smooth tin plates flowing like water, shiny galvanized plates glittering like mirror and other colorful coated sheets. They can then be pressed into cans or applied on industrial machines and household appliances or even just for decoration.
Innovative technologies. One of the most outstanding products in the ANDRITZ Metals portfolio is its patented S6-high rolling mill.

The difference between hot-rolling mills and cold-rolling mills comes down to the required temperature when forming the steel. Cold-rolled steel products usually have higher precision, strength, and surface finishes. Hot-rolling is less expensive, provides better workability, and adds little to no internal stress as the steel cools gradually.
Driven by the technology of pulling and roll manufacturing in the cold rolling industry, the requirements for increasing the wear resistance, roughness retention, hardness uniformity and anti-accident of cold rolls are increasing, with the aim of achieving free rolling., rolling high-grade plates, reducing roll consumption and so on.

If the temperature is below its recrystallization temperature when mental rolled, the process is called cold rolling. Cold rolling is fulfilled by making steel strip through plenty of tandem rolling mill stands. And each one of stands has vertically stacked rolls that are powered by a huge motor to impart high compressing stresses into the strip.
Cold rolled steel (also known as CR steel) is a steel which is roll-pressed at (or near) the room temperature to get the desired shape. In cold rolling operation, the temperature of the metal remains below its recrystallization temperature. In cold rolling, the strength of the metals increases by around 20% due to strain hardening.
Simply speaking, cold rolling is processed and rolled on the basis of hot-rolled coils. Generally speaking, it is a process of hot rolling – pickling – phosphating – saponification – cold rolling. Cold rolling is made of Hot-rolled sheets at room temperature. Although cold rolling also warms up the steel plate during the process, it is ...
Cold rolling mill design types can be divided into many kinds, can meet different processing needs to be customized. According to different standards to distinguish the type of mill. If you choose according to the plate processing, cold-rolling mill used in the processing of sheet metal can be hot-rolled and cold-rolled two, in the precise ...
Cold Rolling Mills. Among the areas covered by Ingeteam is the market niche related with Cold Rolling Mills, for carbon and stainless steel. Cold Rolling is a continuous high speed deformation process, keeping the temperature below the crystallization point. The change in volume occurs in the direction of rolling (with hardly any deformation in ...
A rolling mill which uses the "hot rolling" method is capable of processing more gross weight of metal than any other manufacturing process. Rolling mills which use the "cold rolling" method can process the most tonnage from the entire range of cold working processes. There are many types of rolling processes used in rolling mills, including ...

The diameter of the 6-high work rolls amounts to approximately 1:4 in relation to the barrel length. In comparison to a 4-high mill stand, the utilization range is wider. This type of rolling mill is mainly used in offline applications for cold rolling of soft and medium strip and for a …
After heating, the strip is made of cold rolling mill and hot rolling mill. The finished steel of hot rolling mill is cooled to laminar flow to establish temperature band. It is coiled in the coil by winding machine, and coil cooling is a finishing operation according to different needs. Users straighten the cross-section of leveling line.
Cold rolled steel (also known as CR steel) is a steel which is roll-pressed at (or near) the room temperature to get the desired shape. In cold rolling operation, the temperature of the metal remains below its …
Cold rolling reduction is an important factor that affects drawability of IF steel. It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and the …
