Wehrhahn will be participating in the ICCX Eurasia 2024 exhibition and conference from 4th to 5th December 2024.

Our team invites you to learn more about all aspects of AAC production with new developments in production technology and our automation innovations of production processes. 

Additionally, learn more about Wehrhahn technologies and production plants for producing fibre cement sheets and high-quality quickllime.

Our fibre cement specialist, Rainer Becker, gave a presentation on „Sheet thickness control system optimization through mathematical modelling and self-learning pump maps“.

Intelligent control systems are a vital part in all Wehrhahn production plants. In fibre cement sheet production plants the automatic sheet thickness control system has a decisive influence on the plant performance and feasibility.

A general issue with sheet thickness control is the linked structure of the various controllers involved for tank filling levels, slurry throughput, felt speed and slurry density. Time lag and mutual dynamical influences can lead to increased sheet thickness tolerances under certain operating conditions such as plant start-up or e.g. in the event of process disturbances by changes in flocculation efficiency or increasing pipe clogging.

Here considerable improvements can be achieved.

The smart conversion of the outdated “crane-operated” precuring section has challenged Wehrhahn to develop a worldwide unique technology in order to store the moulds at an elevated precuring chamber.

As a result, the highly advantageous system has fully eliminated numerous labour forces previously needed in the section and has reduced the precuring time as well as energy consumption significantly.

Finally, the cherry on top is the Wehrhahn Master Control Server (MCS). The smart system combines production data from all sections and provides the user with priceless information from production and energy management up to quality control and preventive maintenance.
