A range of services for the steel industry

HYD&AU FLUID has developed an active partnership based on customer satisfaction and service.

Spotlight on the ARCELOR MITTAL Group:

Global leader in the steel industry on the following markets: construction, packaging, automotive, household appliances, etc. It produces steel, flat steel, long steel, stainless steel, wires and structural plate.

With its head office in Luxembourg, the Group has 245,000 employees in more than 60 countries, and turned over €58 billion in 2015.

In France, the three largest production facilities are:

  • Dunkirk in Nord
  • Fos-sur-Mer in Bouches-du-Rhône
  • Florange in Moselle
Creation of a brand new system of stainless steel pipes on the steel rolling mill, including:
  • X-ray inspection for weld conformity checking
  • pipe testing: increase in pressure to 450 bar for 30 min to check the solidity of the system
  • rinsing of the pipes to obtain an acceptance level of pollution for correct operation of the servo control valves
Protection of manufacturing operators:

HYD&AU FLUID created a system for safeguarding the hydraulic circuits of 3 rolling mills according to new ISO 13849 standards.

An innovative and specific system was developed to enable automatic depressurisation in the circuits in the event of intrusion in the zone.

This system has been duplicated for other applications and other customers.

Improved filtration by the rolling mill’s hydraulic power unit:

HYD&AU FLUID replaced an older generation of duplex filter with 4 PALL filters.

These filters are smaller and can be changed individually, making subsequent maintenance work easier.
