Roll cooling systems

Optimize your rolling mill with the use of GRIP zone cooling.

For steel rolling mills

Optimal solutions for:

  • Cold rolling mills
  • Hot rolling mills

For installation in:

  • Tandem plants
  • One-way systems
  • Reversing systems

Customized zone cooling systems for all common automatic flatness control systems (AFC) for 4-high and 6-high rolling mills.

Integration possibility with all existing control systems via open interface, BUS- and manufacturer-independent.

We supply all typical zone widths such as
50 mm, 52 mm, 75 mm, 100 mm
or according to individual customer requirements.

The free arrangement of the spray nozzles permits optimum roll cooling and roll gap lubrication with the best possible flatness results.

The cooling bars are manufactured with high precision. The assembly points are optimally planned for the specific plant in order to reduce the downtime of the rolling mill during installation to a minimum.

The cooling bars are made of steel or stainless steel according to customer specifications.

A high-quality selection of materials for the valve parts ensures corrosion resistance when commercial coolants, emulsions and rolling oils are used.

Due to a possible multi-chamber design of the cooling bars, systems can be operated with different pressures or coolant temperatures.

Common applications:
Base + Additional cooling.

Plant optimization through extremely fast reaction and switching times of the valves of less than 20 milliseconds.

The replacement of existing multistage cooling bars (3/5 zones) by a GRIP system with modern multi-zone cooling allows a significant improvement of the end product.

  • increase in production
  • quality improvement
  • Low inspection and maintenance costs
  • Short downtimes for maintenance work

For aluminum rolling mills

Optimal solutions for

  • Hot rolling mills
  • Cold rolling mills
  • Foil rolling mills

for roll and strip cooling.

Customized zone cooling systems for all common automatic flatness control systems (AFC) for 4-high and 6-high rolling mills.

Integration possibility with all existing control systems via open interface, BUS- and manufacturer-independent.

We supply all typical zone widths such as
50 mm, 52 mm, 75 mm, 100 mm
or according to individual customer requirements.

Also available with Narrow-Edge or Hot-Edge configurations.

Best flatness results and avoidance of strip patterns on the rolled stock due to user-specific optimized nozzle alignments.

The cooling bars are manufactured with high precision. The mounting points are optimally designed for the specific plant in order to reduce the downtime of the rolling mill during installation to a minimum.

Typical cooling bar design in aluminum; on customer request also available in steel or stainless steel.

A high-quality selection of materials for the valve parts ensures corrosion resistance when using commercially available rolling oils, kerosene and additives.

Due to a possible multi-chamber design of the cooling bars, systems can be operated with different pressures or coolant temperatures.

Common applications:
Cooling, hot edge, cold spray.

Plant optimization through extremely fast reaction and switching times of the valves of less than 20 milliseconds.

As an ideal replacement for existing pneumatically controlled cooling systems, the customer benefits from:

  • increase in production
  • quality improvement
  • Low inspection and maintenance costs
  • Short downtimes for maintenance work

For non-ferrous metal rolling mills

Optimal solutions for:

  • Cold rolling mills
  • Hot rolling mills

For installation in:

  • Tandem plants
  • One-way systems
  • Reversing systems

30 years of experience

Tailor-made solutions for our customers.

GRIP Engineering stands for incomparable quality and reliability.

The selective roll cooling systems are extremely low-maintenance due to the use of the continuously improved valve. They have proven themselves for decades under the toughest conditions in the world market. The electrically operated valves operate virtually maintenance-free over millions of switching cycles thanks to their seal-free design.

Cooling systems for new rolling mills are developed together with the customers. When retrofitting existing cooling systems, we always find an ideal solution that enables customers to modernize existing rolling mills with minimal downtime.

GRIP Engineering’s selective cooling systems work with all available shape meter rolls and are available in different cooling zone widths.
