Modernization is cheaper than new construction
In April already JSC „Stupino Metallurgical Company“ (SMK) placed an order with Siempelkamp to modernize the water-hydraulic control of a 100-MN press of Schloemann make as well as to provide for a corresponding new die heating system. Also for the modification of the water-hydraulic control of a 46-MN closed-die forging press into an open-die forging press SMK decided in favor of the machine builder as professional business partner located in Krefeld. Owing to this order Siempelkamp demonstrates its position as full-line supplier for press plants: mechanics, hydraulics and electrics are all from one source.
SMK is one of the leading manufacturer for products made of heat-resistant nickel alloys and special steels for the Russian aircraft industry: The Siempelkamp customer makes parts for gas turbine drives. For its location Stupino near Moscow SMK has been now projecting modernization and retrofit of existing plants: owing to the new Siempelkamp hydraulic systems the customer is able to provide for a more precise control of the presses maintaining the central water-hydraulic stations.
By means of the water-hydraulic control especially developed for the modernization of a 100-MN Schloemann press the moving crosshead can be positioned more precisely by up to rates of 0.15mm/sec. Additionally the parallelism of the moving crosshead is supported under all conditions of operation. The innovative Siempelkamp system is also beneficial for the following reason: special curves for speed and pressure of the press are programmed and subsequently stored for individual products. During the forging process a detailed report of the achieved values that are subsequently filed is given to the user.
Included in the modernization package of the 100-MN press are additionally the electric control and a die heating system. The latter one is completely integrated in the control keeping the die at a constant temperature of 900°C during the forging pause.
Through the modernization process repeatability, recording and filing of the actual forming procedure is ensured. In addition to that the production of work pieces made of granulated heat-resistant nickel alloys is enabled through the technology „HIP + forming“.
For the modification of a 46-MN closed-die forging press into an open-die forging press Siempelkamp will also supply a new water-hydraulic control as well as electric control for the plant of Stupino. The open-die forging press can subsequently make up to 60 strokes per minute. Additionally two rail-bound manipulators with rotary table will be integrated into the installation.
For both modifications in the field of water-hydraulic controls Siempelkamp relies on the cooperation with Hauhinco Maschinenfabrik G. Hausherr Jochums GmbH & Co. KG in Sprockhövel. Hauhinco is one of the leading system suppliers for water-hydraulic systems, high-pressure pumps, valves and industrial components. The expert successfully realized for instance the modernization of the water hydraulics of the 500-MN closed-die forging press at Alcoa Forging & Extrusions in Cleveland, the biggest press in the United States, in the year 2010.
Upon the signatures of the contract the Siempelkamp engineers directly started with the design works; commissioning of both presses are scheduled for the end of 2012. After completion of all works the presses at SMK will meet with the strict requirements of the aircraft industry. In fact these presses will turn to new presses – however at lower cost for project realization that for a new plant.
