Your Advantages with the Langzauner Refractory System

Complete Solution

Press and setting system from a single source – without interface issues.

Langzauner supplies the press and setting system as an integrated complete system from a single source – including automation, handling, and control technology.

Unlike modular systems involving multiple suppliers, this creates a fully integrated system without interface losses.

In practical terms, this means:

  • perfectly coordinated motion sequences between press and setting system
  • synchronized process steps for short cycle times
  • centralized control of all components via a uniform architecture
  • minimized risk during integration and commissioning

For the operator, this results in higher process stability, reduced coordination effort, and maximum system performance.

High Pressing Force

Up to 25,000 kN pressing force for maximum compaction.

The hydraulic press systems achieve pressing forces of up to 25,000 kN or more and are specifically designed to meet the requirements of the refractory industry.

This high pressing force enables:

  • optimum compaction, even for complex geometries
  • consistent density distribution across the entire component
  • reduced porosity and increased product service life

The combination of pressing force, precise control, and robust machine design creates a stable, reproducible pressing process for industrial series production.

Maximum Energy Efficiency

Up to 50% lower energy consumption compared to standard market systems – thanks to an innovative hydraulic concept.

The hydraulic system is consistently designed for energy-optimized operation in continuous industrial production.

Through demand-based power control and efficient system design, the energy used is precisely matched to the pressing process.

This enables:

  • reduction of energy losses during partial-load operation
  • avoidance of unnecessary pressure and volume-flow peaks
  • optimized utilization of installed power

Compared to conventional press systems, energy savings of up to 50% can be achieved.

Up to 50% less energy means:

  • lower operating costs
  • faster ROI
  • more sustainable production

Higher Productivity

Up to 30% shorter cycle times enable significantly higher output per system.

The complete integration of press and setting system enables optimally coordinated motion sequences and minimal downtime.

By synchronizing all process steps:

  • non-productive times are reduced
  • material flows are optimized
  • cycle times are shortened

The result is significantly increased output while maintaining stable process quality.

Depending on the application, productivity increases of up to 30% can be achieved.

30% shorter cycle times mean:

  • more output per shift
  • improved OEE
  • faster amortization

Automated Production

Fully automated from raw material to stacked green brick.

Langzauner implements fully automated press lines for the refractory industry, with all process steps seamlessly connected.

From raw material to stacked green brick, production takes place without manual interfaces.

This includes:

  • continuous material supply and precise dosing
  • precise mold filling
  • synchronized pressing cycle
  • automated removal and transfer
  • setting system with stacking function

Benefits:

  • consistent process quality
  • reduced sources of error
  • higher system availability
  • minimized personnel requirements

Innovative Hydraulic Concept

The specially developed hydraulic system reduces energy losses and improves the process stability of your system. In Langzauner’s hydraulic press for the refractory industry, it is designed for energy-optimized and stable production operation. Through demand-based power control and minimized energy losses, energy usage is precisely matched to the pressing process.

This results in:

  • reduced energy consumption in continuous operation
  • lower thermal load on components
  • more stable and precise press movements

Your benefits at a glance:

  • up to 50% lower energy consumption
  • reduced heat generation in the hydraulic system
  • more precise control of the press movement
  • significantly lower operating costs (OPEX)
  • higher process stability in series production

Efficiency gains in industrial refractory applications:

Especially in large-scale press systems for refractory products, the energy-optimized hydraulic concept offers considerable savings potential over the entire service life of the system. At the same time, overall performance is improved through:

  • more stable process conditions
  • higher repeatability
  • reduced downtime

The result is an energy-efficient and cost-effective production solution for industrial series production.

Fully Automated Setting System

After the pressing process, the automated setting system takes over the complete handling of the green bricks.

The system includes:

  • discharge table
