SCHLOEMANN RAILWHEEL PRODUCTION LINE INCLUDING 10,000 TON SCHLOEMANN HYDRAULIC 4-COLUMN CLOSED DIE FORGING PRESS

This is a classic Rail Wheel manufacturing setup. Further, the primary components are designed by
Schloemann, an outstanding producer of Forging Machinery. In addition to Rail wheels, this line is also suited to the production of crane wheels – any type of steel wheel, gear blanks, etc.

Below is a list of components however, the primary production machinery making up the wheel
production line includes a 10,000 Ton Schloemann Hydraulic Closed Die Forging Press, a Schloemann Wheel Rolling Mill (like a Ring Mill) and a 3,000 ton Schloemann Hydraulic Punching & Coining Press. This complete line is still installed even though is has not run production for a number
of years. It was used to forge railroad wheels, crane wheels and gear blanks. It can be seen in it’s original state – still installed.
For Rail Wheels, starting billet size used was 13” – 24” in diameter weighing between 850 lbs. –
3,500 lbs. (pounds). The 10,000 ton press blank-forges the billet into a circular wheel shape. The forged blank is then moved to a Scholemann Ring Rolling mill which has 2 rolls, each driven by a
400 HP motor. The last operation is performed by the 3,000 ton Schloemann hydraulic press which
pierces the hole on the center of the rail wheel and forge forms the middle section pushing it out.
The line consists of the following:
• Stock Bench
• Block Scale
• Block Conveyor
• Charging Manipulator
• Rotary Furnace
• Discharge Manipulator
• Transfer Car
• 2,500 PSI Descaler
• Schloemann 2,500 – 5,000 PSI Intensifier
• 10,000 ton Schloemann Hydraulic Closed Die Forging Press
• Schloemann Wheel (Ring) Rolling Mill w/(2) 400hp motors
• (4) Turn Over/ Transfer Devices
• Automatic Wheel Stamping Machine
• 3,000 ton Schloemann Hydraulic Punching & Coining Press
• Pump Room w/(5) Hi-Pressure Pumps w/Gearboxes & Motors each equipped with a 700 hp
General Electric Drive, (2) Water Storage Tanks, (1) Water Bottle, (3) Air Bottles
• (72) Slow Cooling Pits.

General info & specs for the 10,000 ton Schloemann Press are as follows:
This 10,000 ton Schloemann Hydraulic Closed Die Forging Press provides the power necessary to
achieve dramatic reduction ratios and material flow which are essential in high quality forgings. The
Closed-Die design provides excellent strength-to-weight ratios necessary for the most critical forging
requirements.
Products produced:
Crane Wheels up to 42" diameter in hardness ranges up to 62m Rc (700 BHN).
Industrial Wheels up to 42" diameter
Sheave Wheels up to 52" diameter
Gear Blanks & Rollers up to 48" diameter
Extractors I and II
Extractor I in press center is used for transferring the material from UVG into UFG by means of Z.-
MANI
Extractor II outside the press center is employed for lifting the forged wheel out of the UFG and for
transferring same to the turnover (RDT-MANI). For resetting of the top dies into the top end position.
2 pusher-type return devices are arranged in diagonal in bottom crosshead of press. The pushertype
return pistons act directly on to the moving crosshead of the press, this crosshead being the
base for the upper tool shifting device.
The lower tool shifting device is supported on the bottom crosshead of the press.
All motions of GSPR are initiated and executed by hydraulic cylinders. The high-pressure water
supplied through valve controls is taken from the high-pressure accumulator having a pressure of
p=200 atms.
