Cold rolling of steels the primary purpose of cold rolling of steels is to reduce the thickness of the hot rolled steel strips (normally in the range of 15 mm to 5 mm) into thinner thicknesses (usually in the range of 012 mm to 25 mm) which cannot be normally achieved during hot rolling in a hot strip mill. Cold rolling forms hot rolling 6 hot rolling hot rolling is a metalworking process that occurs above the recrystallization temperature of the materialhot rolled metals generally have little directionality in their mechanical properties and deformation induced residual stresses.

Tension bridles for a cold rolling reducing mill are provided the reducing mill reduces the thickness of a metal strip passing through the reducing mill the tension bridles create tension on the metal strip between the bridle and the first reducing stand to receive the metal strip and between the final reducing stand and the exit bridle so that a greater reduction can be made in the. Reversing cold mill advanced reversing cold-mill technology from primetals technologies is an ideal solution for small- to medium-sized production capacities, or for the rolling of smaller order lots of special steel grades. For the cold rolling process, this translates amongst others into new designs of mills, which release less oil fumes and allow reduced energy consumption this brings improved comfort for the operator as well as enhanced durability and a lighter environmental footprint of the equipment. The cold rolling mill produces 120,000 tpy of aluminium coils, coming from two casting machines, with a thickness of 10 to 6 mm and which are rolled down to a minimum thickness of 015 mm at a max speed of 1200 m/min, with a max strip width of 21 meters. As a manufacturer with more than ten years of cold rolling mill development, production, sales and installation, gongyi jindi metallurgical equipment co, ltd will explain the operation test of rebar cold rolling mill in the followingthe running test of the cold rolling mill machine usually has three items, one is the idling test, the second is the load test, and the third is the accuracy test.

Data from nine steel rolling operations were used to define the volatilized portion of lubricants used in rolling operations and to prepare total oil, grease and hydraulic fluid material balances for actual and typical cold and hot rolling opera- tions. At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods many of these products will be the starting material for subsequent manufacturing operations such as forging, sheet metal working, wire drawing, extrusion, and machining. In cold rolling mills, vibrations of mechanical parts and/or the strip can affect several quality parameters such as thickness, shape, surface quality, etc since vibrations mainly occur at higher speeds, in most cases the rolling speed of single- or multi-stand mills for steel and aluminum has to be limited.
