Improved Performance

Providing an intelligent Pinch Roll and High-Spead Laying Head from the Morgan product line, Stahl Gerlafingen will improve production performance by ensuring uniform packaging of the coils. Improved coil packaging allows the reheating furnace to be utilized fully, and the coil can be shortened to ease transportation.

Minimized vibration levels

The wire rod mill produces 600,000 tons of coils annually, while the bar outlet has an annual capacity of 80,000 tons of bars. Both machines are fed from the same roughing and intermediate mill train. The upgrades will lower the vibration levels, resulting in reduced wear. AFV Beltrame Stahl Gerlafingen will also achieve better control of the tail ends and front-end positioning.

Electrical equipment

New AC motors will be supplied for the pinch roll and laying head. The motors are controlled by Sinamics S120 variable frequency drives with an AFE rectifier. Technological control will be realized with a Simatic S7-1500 PLC controller.
