Galbiati Group has recently implemented the biggest ever constructed gear reducer addressed to Siemens Vai Pomini.
Worm screw gear set ,consisting in a helical five assets wheel for screw down drive; composed of two symmetrical parts, with a weight of about 28,000 kg each.
Command reducer for the opening of the cylinders of the roughing mill, hot reversible with relative maneuver screw-down.
Below we report the operation test of the screw-down drive, presided at the assembly area of the Galbiati Group and to the satisfaction of the final customer.
Worm screw gear set for screw down drive; 970 mm center distance, ratio 29.5. 87 tons total assembly weight, including support frame, auxiliary equipment, breaks, auxiliary gear motors, etc.
Galbiati Group designed and manufactured large crop shear drives.
The figure shows a 1.600 kW at 27 rpm crop shear drive, max 6.000 kNm torque. Total unit weight exceeds 160 ton.
NiCrMo Output gear wheel, double helical ISO-DIN quality 6 finish, 600 + 600 mm width, m 32, more than 3 m outer diameter, total weight 40.000 kg approx .
3.000 kW power at 0/9.1-15.2 rpm during full speed test to check the oil flow rate, pressure and temperature, bearing temperatures and vibrations, and noise level of the rotating parts.
In the category “Global Competitiveness” Galbiati Group Srl was nominated “Supplier Star” for the demonstrated ability in working with Siemens VAI MT, for the design and construction of power transmission parts for rolling mills and casting plants; Auer also highlighted as Galbiati Group Srl well-established a good cooperation with Siemens VAI MT “ providing operational flexibility and high quality, all combined with speed and accuracy in delivery, key features that make Galbiati as the best provider for Siemens Vai of components for metallurgic plants. ”
The Galbiati case is still school: following the event of the last July 8th 2011 2011 it was now the venue for the 21 Assiot affiliates whose Galbiati case history was presented, in cooperation with Staufen, on Friday October 28th 2011. Optimization of production and lean production were the issues covered during the event, both on a theoretical and academic point of view thanks to the great presentation of Dott. Giancarlo Oriani,managing director of StaufenItalia, and on a practical one, through the visit to the facility by all Assiot affiliates (mechanical workshop and assembly department).
One of the strategies, which led to excellent results in terms of production optimization and searching for new prospects is the one Galbiati Group introduced in collaboration with RDI, Staufen and Ecipa Lombardia, in a conference which saw the participation of Sebastiano Barisoni. (Il Sole 24 Ore) as moderator and Professor Alberto Portioli from the Milan Institute of Technology, explained the principles of lean production and innovative communication to the public.
Galbiati Group was rewarded from Hatebur, productive leader of mechanical horizontal printers, like best supplier 2010. We receive this important recognition with large pleasure and satisfaction.
“We were glad to present this special award to Galbiati Group S.R.L. in recognition for their merits in mechanical processing.”
Thanks, there is not better manner “to crown” the first work decade together, and get ready to confront the next one.
Galbiati Group designed and manufactured a complete integrated pinion stand mill drive for special alloys milling (silica, tungsten, vanadium, etc.) for an Austrian customer. The plant consists of a reversible mill stand driven by an integrated pinion stand mill drive, equipped with two pinions meshing together on a center distance just less than 1 m and running at 50 rpm. Input shaft is connected by a toothed coupling to two motors in series, with a total power of 2.400 kW at 195 rpm. This provides a transmissible torque of approximately 460.000 Nm with a suitable service factor, or a nominal torque that greatly exceeds 1.000.000 Nm.
