According tothe type of rolling mill: (1) Flatroll. That is, therollbody of plate and stripmillis cylindrical. Generally, therollof hotrollingplaterolling millis made into micro concave shape, which can obtain better shape when heated; therollof coldrollingplaterolling millis made of micro convex shape, and therollwill bend duringrollingto obtain good shape.
Lattertypeofmillis similar to the planetarymill. It utilises a small freely rotatingroll, mounted at the end of an arm which is forced to reciprocate like a pendulum at high speed over the deforming metal. The metal is fed towards the pendulumrollby feedrollsat around a speed of 10 mm/sec.
5. ClusterRolling Mills: In thistype of rolling mill, there are two basic roles that are backed up by two or morerollswhich are bigger than those two basicrolls. These backed uprollsgive more pressure to the basicrollsto heavily press the strip.

There are two types of rolling mills – electrical and manual. Although almost all smaller jewelry studios are equipped with a manual rolling mill, an electric one makes a lot of sense for a larger venture, as it allows for faster, large-scale production. Of course, it does cost a lot more than a manual rolling mill.
Most steel mills have rolling mill divisions that convert the semi-finished casting products into finished products. There are many types of rolling processes, including ring rolling, roll bending, roll forming, profile rolling, and controlled rolling.

Rolling millsare one of the more expensive jeweller’s tools, and although simple in nature, themillcan be put to many uses. When buying arolling millmachine, like many tools, you should buy the bestmillyou can afford , with the bettermillsbeing more robust and having heavier and stronger rollers.
However, because therollingparameters can be quickly changed for each coil, reversing coldmillsare especially suitable for the small-lot production of various producttypes. The size of themillequipment is also smaller, which allows easier access tomillequipment and machinery for maintenance purposes.

In a metalrollingprocess,rolls, stands, bearings, housing, motors, and other mechanical equipment are all a necessary part of the manufacturing operation. The place where all the equipment for metalrollingmanufacture is set up is called arolling mill.Rolling millsoften vary inthe type, number, and positionof rolls.
There are many types of steel rolling mill machine that used to reduce the thickness of metal material or compress the material to create a uniform product such as the plate, wire rod, rebar, hot rolled coil, cold rolled coil and etc. In addition, the steel rolling mills are divided into several types as follows: Two-high rolling mills, which have a unique advantage in cost-saving cause the less expensive for manufacturing.
Rolling Mill Equipments Rolling Mill Equipments are widely used in steel rolling mill machinery and rolling mill plants for rolling down sheets, slabs and coils that are made up of various metals mainly aluminum, copper and stainless steel. These are extensive used for production of rods, TMT, squares, angles, wires, coils, H-I Beams and channels.
Of course,rollsshould be checked to ensure they have been installed on the correct stands. Once a year, themillshould be aligned. Amillalignment usually takes one or two days and is most often done by a professional. Every day, themilloperator should use a setup chart and follow all operating procedures.
