Pickled coils are rolled in twin stand cold rolling mill where they are processed into a specified thickness. Generally, the rolling reduction ratio is 50% to 90%. The critical point at this stage of the process is to maintain uniform and precise flatness throughout the entire length of the coil.
#0183;#32;They have advanced technology to bring perfection in work, and easy availability of transportation has opened the door for fair business. There are two major types of rolling mills, and one is hot rolling mills and second is the cold rolling mills. Lets see how the operation of hot rolling mills
With the advancement of technology in rolling mills, the size of rolling mills grew rapidly along with the size of the products being rolled. One example of this was at The Great Exhibition in London in 1851, where a plate 20 feet long, 3 #189; feet wide, and 7/16 of an inch thick, and weighing 1,125 pounds, was exhibited by the Consett Iron Company .

Unlike many other manufacturers, we do not use readymade heat treatment units delivered from plant suppliers. We solely deploy our selfdeveloped technology known and introduced worldwide under its brand name HSH#174; Technology. Thus, we are able to heattreat practically any, even the most complex rail profile, in ultralong rolling length.
In the rolling process, the mandrel speed is not controlled, and the mandrel is driven by the friction force of the rolled metal to follow the pipe freely through the rolling mill; During the rolling process, the running speed of the mandrel fluctuates with the biting in and steel throwing of each stand, resulting in the fluctuation of the wall thickness of the pipe; after the rolling, the

all rolling schedules including stresses in the roll. As regards abnormal rolling conditions which are more or less very normal for rolling mills roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll
It is the widest Hot Strip Mill in India, capable of rolling upto 2150 mm. JSW Steels Dolvi unit in Marastra has commissioned capacity of MTPA . The Dolvi unit HSM uses a combination of the advanced Conarc Process and Thin Slab Casting technology, which facilitates the production of HR coils which are superior in quality due to their thinner gauges and finer surface quality.
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.
