rolling mill can b e designed as 20 Hi, 12Hi, 8 Hi, 6 Hi, 4 Hi and 2 Hi rolling mills. In India now a days mostly 20 Hi and 4 Hi rolling mills are installed in bi g steel produ ction units.


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 wide range of strip widths.


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 time of holding [35].


The cold rolling without annealing is called rolled coil. Rolled coils are generally used for products that do not need bending or stretching. Rolled coils of less than 1.0 thickness have good luck in bending both sides or four sides. Cold rolling is usually annealed. Cold rolling oil must be used in cold rolling process. The advantages of ...


The rolling mills are similar to that used in hot rolling. The cold rolling process has the advantage of providing close dimensional tolerance up to 0.025 mm. It also improves toughness, hardness, mechanical strength, surface finish of the material. Softer metals like tin, …


In cold forming metal is formed at high speed and high pressure into tool steel or carbide dies. The cold working of the metal increases the hardness, yield, and tensile strengths. Cold Root Rolling: Cold root rolling is the process of burnishing the root radius of a previously cut thread, in a Rotary Shouldered Connection or thread profile. A ...


Cold rolling is a technique where a metal strip or sheet is passed between two rollers and then squeezed and compressed. The level of strain present determines the properties and hardness of the finished material. This process is widely used for surface finish and high-quality dimensional accuracy, which can help prevent material damage and ...


In the article of How Many Types of Rolling mill, we knows that rolling is divided into two types that is hot rolling and cold rolling according to the different of the temperature when metal rolled.

Cold rolling mill - ArcelorMittal in Belgium


Simply put, rolling mills are used to decrease width and increase hardness of the metal. Though there is more to a rolling mill than this simple definition. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform.


The continuous casting billet sent from the steel mill first enters the heating furnace and then passes through the rolling mill repeatedly and then enters the finishing mill. Rolling steel is a metal pressure processing. In the hot wire rod rolling mill line, the rolling workpiece is softened, fed into the rolling mill by the roller conveyor, and finally rolled to the required size required ...


Cold rolling is a round bar that is rolled into regular sections on a cold rolling mill to improve its strength and adhesion to concrete. When the steel bar is rolled in cold rolling, it deforms both lengthwise and crosswalk at the same time, so its plasticity and internal structure uniformity can be …
