Bar Mills are set up to produce TMT/QST rods from sizes 8mm to 40mm . In these plants the raw material used are Billets. The Billet is passed through various stands to get the desired shape and size.
Our mills can be fullyautomatic or semi automatic as desired by customer. We have divided tmt bar rolling mills according to their capacity 60,000 TPA TO 80,000 TPA (Furnace capacity 16/20 TPH) 100000 TPA TO 1,25,000 TPA (Furnace capacity 25 TPH) Upto 250000 tpa (Furnace capacity 30-40 TPH) 300000 TPA to 500000 TPA (Furnace capacity 5O -100 TPH)
Calculate the RPM setting to perform this cut. Cutting Speed = 60 (fpm) Diameter of part = 0.75. A 1-inch (HSS) drill is used on a 4-inch diameter piece of 1012 steel with a brinnel hardness of 100. Calculate the RPM setting to perform this drilling operation. Cutting Speed = 140 (fpm) Diameter of the drill = 1.00

When a hot rolled bar leaves the final mill stand (including roughing mill, intermediate mill, finishing mill, etc.), it is instantaneously quenched 9 a type of heat treatment where the rebars are rapidly cooled to obtain certain material properties) using a special water spray system in the quenching box.
is 300 mm, and the rolls rotate at 100 rpm. Calculate the roll force and the power required. For annealed copper, it has a true stress of about 80 Mpa in the unstrained condition and at a true strain of 0.223, true stress is 280 Mpa.
bar; in-line heat treatment, and the use of micro-alloying additions. In-line heat treatment is sometimes referred to as Quench and Self Tempering (QST). In this process, high pressure water sprays are directed onto the surface of the bar as it exits the rolling mill. The short duration of the quench transforms only the surface of the bar to a hard

bar and now delivers multiple strand of equal sections to their respective finishing lines. For the effective continuous operating of the slit rolling process it is important that all mill equipment is in good order. Particular care and attention must be directed to the condition of the rolling mill…
GPH TMT 500W bar is produced by fully automatic, computerized machines based on sophisticated and accurate advanced technology and design. The thoroughly tested billets are reheated under controlled temperature in automatic reheating furnace at 1100-1200°C and are subsequently rolled through a sequence of rolling stands progressively reducing to the required size.
TMT stands for the thermo-mechanical treatment of bars. TMT rod or TMT bar manufacturing is a medium or large scale operation. It is a highly profitable business depending on the manufacturing technology you are using. In this article, we intend to explore how to start a rolling mill business or TMT bar manufacturing business.
