10000kN Direct Motor Drive Screw Press for Hot Forging
The drive system is the most important part for a screw press. In LS Heavy Industry Engineering Co., Ltd., drive system of AC asynchronous motor based on direct torque control technology is successfully used in electric screw presses. It has more advantages than the drive system of permanent magnet AC servo motor based on vector control technology.
No impact to power grid
Direct control of torque
Quicker response of torque
Larger energy output capacity
Less temperature rise of motor
Lower cost of the press
Ease maintenance
Higher quality reliability
Dual-motors are used for one screw press. The blow – time curve was made through taking samples of slider displacement and speed at each 10 ms

Full line: Slider displacement
Dotted line: Slider speed
OA: Slider descent
AB: The release of energy during blow
BC: Acceleration of slider return
CD: Deceleration of slider return
Many experiments made in forging plants testify that the thickness of braking plates on two sides of the press reduce only 2 mm after 3,000,000 strokes. In the manufacture of air valve, the presses well perform after 15,000,000 strokes.
Tail-made design for customers
LS Heavy Industry Engineering Co., Ltd. helps customer develop software which fit to its forging process, and to analyze forging data for obtaining the optimum forging expertise, improving forged parts quality. The following table is from the forging process of blades made from titanium alloy.
Features:
