Press-Forging Workshop No.2 is a highly mechanized shop equipped with a radial-forging machine SMX600/12MN, a high-speed 16MN forging press (SMS MEER, Germany) and a 63MN horizontal extruding press.
The range of products includes: round, square and profile forgings and billets.
The highly automated forging process and optimal layout of metal deformation result in production of top-quality forgings and billets.
Horizontal press 63MN is designed for manufacturing pressed article dia. 80-210 mm complex alloyed, difficult-to-form alloys.
The workshop also accommodates 3-ton and 7-ton hammers for the production of round and square forging sock 60 – 200 mm and rectangular forgings 30-120х100-300 mm.
The workshop is equipped with heat treatment facilities and surface finishing equipment.
Press-Forging Workshop No.3 is a brand-new shop for the manufacture of high value added products. Modern equipment, designed and installed in 2012 - 2015 includes a closed-die forging press 200 MN forging force, manufactured by Siempelkamp (Germany), two ring-rolling mills by SMS MEER and Siempelkamp, ring expanders made and installed by SMS MEER and Fontijne Grotnes Group (the Netherlands & the USA).
The above-listed equipment operates in combination with the custom-made manipulators supplied by GLAMA Maschinenbau GmbH (Germany) which perform a wide range of manipulator’s functions and at the same time serves to fulfil individual, specific and unique requirements of numerous customers.
Machining floor for surface treatment of rings and closed-die forgings is furnished with the state-of-the-art tuning lathes and vertical boring lathes produced by HONOR SEIKI CO. (Taiwan) and supplied in cooperation with FINVAL engineering company, automated belt-saw machines manufactured by KASTO Maschinenbau GmbH (Germany), and CNC-type waterjet cutting machine supplied by PTV spol. s.r.o. (Czech Republic).
An automated heat treatment line comprises electrical heating chamber furnaces, quenching tanks with oil and water, forced cooling unit, and a charging machine. This line was developed, manufactured and installed by Electrotherm Electrical & Metal Products Ltd. (Israel), one of the leaders in design and development, production and supply of heating equipment including industrial furnaces, heating elements, control and automation facilities. The charging machine was supplied by GLAMA Maschinenbau GmbH (Germany).
A complex of non-destructive testing equipment includes an automated penetrant testing line supplied by ATG s.r.o. (Czech Republic) and a number of automated units for ultrasonic immersion testing of bars, disks and rings from special alloys, supplied by a world-famous manufacturer ScanMaster (Israel).
The product range of the complex: seamless rolled rings dia. 300 - 4000 mm, 30 – 600 mm height, wall thickness from 20 mm; die-forged disks and shafts up to 1200 mm in diameter, weight up to 3000 kg; profile shafts up to 1500 kg.
Rolling Workshop No.1 is furnished with a medium-section rolling mill 600 of linear type for the production of pipe billets, round bars 65-110 mm and square bars 125 mm, and preforms for rerolling on the mill 350/250.
The workshop is equipped with a heat-treatment floor and machining floor.
The calibration floor features all kinds of equipment required for the production of steel with special surface finish, from 3 up to 35 mm in diameter, and calibrated long products from 5 up to 35 mm.
Surface finishing includes turning, grinding, polishing in various combinations.
Furnace line consists of gas furnaces for heat treatment of ingots, forgings and long products up to 6 m in the temperature range of 650-1150˚С, small chamber furnaces for heat treatment of steel products up to 3,0 m long, two of which are high-temperature furnaces with the maximum temperature of 1200˚С.
The furnaces available in the shop are used for annealing, high tempering, quenching with water cooling (austenitization) of long products, forgings and ingots.
Finishing floor is equipped with a centerless turning machine for turning of medium and large long products dia.65-195 mm with minimum surface roughness (Rz) 80 µm, and an automated line “HETRAN” (the USA) for the long products surface treatment to the dia.38 – 200 mm with H9/Н11 accuracy degree and surface roughness (Ra) 5 µm.
Rolling Workshop No.2 consists of the department for the production of hot-rolled sheet with 2,8 – 40 mm thickness and 400-650 mm width, cold-rolled strip with 0,01 - 2,5 mm thickness and 40 - 280 mm width, and cold-drawn wire dia. 0,018 - 7,5 mm and 5 mm square section.
The equipment of the shop includes a hot-rolling mill “Quatro-1000”, a cold-rolling mill “Quatro-400”, a 20-roller mill “160” and “400”, and wire-drawing machines for the production of wire of various sizes, as well as a set of equipment for product pre-heating, etching and heat treatment.
Rolling Workshop No.3 is equipped with a semi-continuous small- and medium-section rolling mill “350/250” for radial-displacement and continuous rolling. The mill is designed for the production of small and medium long products and wire rod from alloyed and high-alloyed steel and alloys in the size range of 6,5 - 75 mm, with round, square, hexagon and flat section.
An automated process control system of the mill regulates the rolling technology and the quality of long products, minimizing consumption of metal for rolling.
Heat treatment and finishing equipment is also available in the shop.
