Mar 15, 2016#0183;#32;Once in the hot rolling line, the billet enters a furnace to be reheated, once at the correct temperature, the billet is pushed into the rolling stands. By passing between successive rolling stands, the crosssection can be modified as can the length. This process takes place in a continuous rolling line where the speed is controlled automatically.

Jan 05, 2017#0183;#32;If the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. Roll stands, holding pairs of rolls, are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel
The processing of steel in cold rolling mills differs considerably from the production in hot rolling mills. The raw material is first descaled (usually pickled, sometimes shot blasted and pickled), then cold rolled and heat treated. Further treatment steps include slitting, skinpass rolling, coiling and packing.

Cold rolling is usually a finishing process in which products made by hot rolling are given a final shape. These processes provide good surface finish, closer dimensional tolerances and enhance mechanical strength of the material. The steel which we get from remelting shop or from steel manufacturing plants is mostly in the form of ingots. Ingots have a roughly square cross section of x, and weighing
Shalimar Steel manufactures steel rerolled sections from graded steel billets, produced from its own plants, Pakistan Steel Mill (PSM) and from imported billets. Following fully automatic steel rerolling mill units are under operation.
only under so called normal rolling conditions and even these change continuously with progressive wear in the contact zone. Besides normal rolling conditions a stable, theoretical assumption mills experience many different changes in rolling conditions. After a roll change or a mill stop rolls need some time to return to stable
The GPH QUANTUM rebar has a rustresistant coating due to its refining and automatic Quenching Method, which increases the rebar''s rust resistance, so it can be used safely in any large installation. Shiny surface: The use of more tungsten carbide rolls in the rolling process makes the surface of the GPH QUANTUM rebar shinier.

The main users of scrapped irons are the local steel rerolling mills producing MS rods, MS bars, angles and steel sheets for domestic market. A furnace is an equipment used to melt metals for casting or to heat materials to change their shape ( rolling, forging) or properties (heat treatment).
In simple terms, cold rolling is the process of strengthening steel by changing its shape without using heat. Cold rolling, unlike hot rolling such as with hot rolled steel, can only occur when a metal is below its recrystallization temperature. Where hot rolling is performed using high temperatures, cold rolling is performed at room temperature.
Ratanpur Group started its operation in 1984 with its flagship company Ratanpur Steel ReRolling Mills Ltd. (RSRM) to meet the growing demand for high quality deformed bars in the market. The population boom created a housing crisis which led to numerous public and private construction projects, creating a greater demand for our products.

Jun 01, 2017#0183;#32;The steel sector in India consists of four branches namely (i) multimillion tons integrated steel plants, (ii) mini integrated steel plants, (iii) individual units of steel melting producing pencil ingots, and (iv) rerolling mills which are rolling steel from billets, pencil ingots and scrap steel.
A fully automated hot rerolling mill was put in place for the production of our rebar. The quality of the rebar is ensured using UTM in a stateoftheart laboratory. Our product samples are sent to BUET every month so that the quality is never compromised. Currently, we are producing different sizes of TMT and 60 Grade rebars.
Steel rerolling process starts with cutting of billets in desired lengths. These are then loaded at pusher platforms from where they are pushed into the furnace. The Furnace may be
