Aperam has two critical dedusting fans in its production. When they are in standstill, the entire production line needs to be stopped, which is very expensive. To optimize productivity, Aperam is looking for:

• Transparency for the assets conditions to prevent unplanned downtimes
• Timely recognition of potential faults and execution of counter measures during standard maintenance intervals

Siemens service experts proposed a complete solution based on the Predictive Services for Drive Systems approach. First an assessment was performed to look for the bottlenecks and possibilities on the existing installation.  

After the assessment the experts connected the motor and frequency converter to MindSphere. On the motor (third party), Simotics Connect 400 was installed to monitor motor vibrations, current and speed. The frequency converters (SIMATIC S120 cabinet modules) were connected via MindConnect Nano. This module transfers the most important parameters, such as currents, temperatures and alarms, to MindSphere.

The information from both - motors and frequency drives - is evaluated in the MindSphere application Predictive Service Assistance. This application monitors the health status of the drive train and launches the appropriate actions when a problem is detected. Additionally, the application also provides transparency on maintenance planning, product lifecycle and spare parts. 

This digital platform is combined with a service contract: Siemens drive experts regularly check the data to make deeper interpretations and provide context to the customer.

The Aperam group is a multinational producer of stainless steel. The plant in Genk has a steel factory and a cold rolling mill. There work more than 1000 people on the Genk plant alone.
