Rolling mill – is a set of equipment, providing a deformation of metals between rotating rollers. By appointment mills divided by crimping, billet, profile, strip, wire, sheet, tube-rolling mills and special purpose. The term "crimp" is a rolling mill and other values. To crimp rolling mills are blooming and slabbing mill rolls with a diameter of 800 to 1,500 mm workpiece large size (Blooms and slabs). Blooming – it's big and heavy blooming for pre-crimping of metal. Additional information at Sela Ward supports this article. Blooming, usually with two roller mills, but there are three. The final products are blooming – it blooms and blanks, which are then sent for further processing into other types of mills.
Blooming and slabbing mill – a double reverse odnokletevye mills. In the slabbing mill has horizontal and vertical rolls. In the slabbing mill has both vertical and horizontal rolls, as they are referred to the universal mill. Billet mills have rolls of diameter 450-850 mm. At these mills rolls processed in the blanks much smaller. Billet mills are used to further crimp blyumov.Chto a bloom? This is a semi-finished steel production, which is a special blank square with a side of more than 140 mm. Source: San Antonio Spurs. Bluma designed specifically for the production of long products. Varietal mills can be roughly divided into three types: heavy-, medium-grade and Light section.
Rail-beam mills used for rolling rails, beams, channels and other complex profiles. Varietal mills as well as the crimp is a duo-trio-mills or with a linear arrangement of the stands. Varietal mills are characterized by the diameter rolls in the last stand. Rolled sheet and strip hot-rolling mills are designed for manufacturing slabs of different thickness (50-350 mm, 3-50 mm or 1,2-20 mm). For rolling bands most in demand shirokopolosovye continuous or semi-continuous rolling mills, consisting of more than 10 stands quarto, and a few stands with vertical rolls. All the rolled material unwound in the special rolls. These mills are the most productive, in contrast to the plates, so they are also used for rolling and heavy plates, which are produced by unwinding of rolls and the subsequent cutting. For the production of aluminum wire and copper alloys are used foundry-rolling mills. With this type of mills can process for continuous wire from the molten metal. Today's wire mills make continuous at work so. Tube units generally consist of three mills. In the first camp of the helical rolling firmware makes the holes in the workpiece. The second mill is required for extract preparation sewn into a tube, and the third – for decreasing the diameter of the rolled tube. The construction of tube assemblies is mainly determined by the selected second mill process, ie, exhaust.
