Primetals Technologies receives final acceptance for modernised rolling mill at JSW Steel in India

well as the Indian producer with the largest installed capacity for long products. The Salem facility of JSW Steel hosts the largest Indian integrated-route steel plant for alloy and special steels. Salem works produce blooms, billets, cast iron and rolled long products in more than 850 special grades of steel, with dimensions ranging between 5.5 and 240mm. Strategically located in the state of Tamil Nadu, the plant caters to the automotive factories of southern India, where the rolled

PRIMETALS Technologies has received the Final Acceptance Certificate (FAC) for a modernised rolling mill for long products at JSW Steel Ltd in Salem, India. The core of the modernisation project was the new reversing roughing group with Red Ring stands, which enables it to increase the size of the blooms to be processed to 220mm. This extends the range of rolled products, both in terms of size and grade. The new reversing roughing

products are used for the manufacture of components like drive shafts, gears, bearings, suspensions, crank shafts and cam shafts. Red Ring is a registered trademark of Primetals Technologies in certain countries.

In addition to the roughing group, Primetals Technologies supplied its mechanisation, the guide systems, a hydraulically-operated shear for cropping after the roughing group, a convertible dividing shear after the existing finishing train, the level 1 automation with mechatronic packages as well as consulting services for the installation and commissioning. JSW Steel is one of the largest steel producers and exporters in India, as

group consists of one horizontal and one sliding vertical Red Ring stand of the fourth generation. Using blooms with 8m length and square size of 160 or 220mm, a reversing sequence with up to ten passes rolls a 104 x 112mm intermediate product, which feeds the existing finishing train. The processed grades consist of special steels for mechanical construction, tool, spring and bearing applications.

Mazak launches new laser machine for cutting small diameter pipe

reduces in-process time required for pipe workpieces and negates the need for processes such as punch press, deburring and hole tapping. The FT-150 FIBER is also equipped with a number of automatic functions, including auto-profiler calibration and nozzle cleaning and is available in four different options, each with a 3.0kW resonator, that can be specified dependent upon the length of the workpiece material being machined, from 6,500mm up to 8,000mm.

FIBER further enhances our fibre laser cutting capabilities with a machine specifically designed the high speed and high accuracy cutting of small diameter pipe. The exceptional productivity delivered by for the combination the fibre resonator, ultra-fast feed rates, the capability to machine multiple different processes and the bundle loader automation, makes the FT-150 FIBER ideal for volume manufacturers looking to make a step-change in their laser processing capabilities.” The new machine can perform multiple processes, including cutting, tapping and thermal drilling, it also

YAMAZAKI Mazak is launching a new laser cutting machine specifically designed for the high-speed cutting of small diameter pipe at Tube 2020 in December 2020. The new laser is capable of cutting round, square and rectangular pipe with diameters up to 152.4mm, dimensions that are typically used in the construction, furniture and architectural industries and also for vehicle body frames. The machine can cut a wide variety of materials, including mild steel, stainless steel, copper, brass and aluminium. Mr Gaetano Lo Guzzo, director, laser business Europe, said: “The new FT-150
