Machineries For Rolling Mills

In the rolling mill technology product range, hpl-Neugnadenfelder Maschinenfabrik GmbH designs and manufactures both new rolling mill and retrofitting technology for all ferrous and non-ferrous metals.


Hpl delivers turn-key solutions reaching from a 2-high up to a 20 roller cold rolling mill as well as hot rolling mills for magnesium. All their products are both highly efficient and high in quality.

  • High level of automation
  • Actuators, such as bending and selective cooling mechanisms
  • Rolling mill stands with hydraulic roll gap adjustment system
  • Roll bending
  • Pass line adjustment
  • Optimised changing devices for work rolls
  • Uncomplicated operation and easy handling
  • Fast and reliable coil transportation

Our lines feature a flexible design allowing them to be adapted to any site conditions. The rolling mills are installed on site and commissioned by us.

We have developed two new technology concepts offering significant advantages for their customers.

The roll housing technology is a completely new approach to the design of rolling mills. This new construction based on a platform concept allows the use of different roller configurations. This enables hpl to carry out retrofitting work, as for example from a 4-high to a 6-high or 12 roller configuration. The resulting advantages are significantly reduced delivery times and the diversification of the service offered by hpl-Neugnadenfelder to its customers.

The second substantial new development consists of an innovative strip position control system. This newly developed control system offers automatic leveling of the rolls due to exact strip centre sensing.


hpl-Neugnadenfelder extends the lifetime and increases the productivity of existing lines – independent of the line manufacturer. Based on the existing rolling mill technology and site conditions, hpl deliver optimal solutions to their customers. hpl scope of supply includes the potential analysis, planning, design, manufacture and assembly of the components and systems to be modernised.

Hpl scope of supply for increasing line productivity includes:

  • Retrofitting, from mechanical to hydraulic roll gap adjustment
  • Retrofitting of actuators, such as bending and selective cooling mechanisms
  • Installation of bending mechanisms for work rolls
  • Automation of control systems
  • Use of highly efficient changing devices for work rolls
  • Increase of drive power

For the retrofitting of existing lines, hpl guarantee their customers minimal machine downtime due to optimal use of the existing infrastructure.
