Rolling Process Researcher

Context

Isbergues Research Center is the laboratory dedicated to the study of stainless steels for the European manufacturing plants of the APERAM group. There are around eighty people whose activity consists of defining, developing and assisting the commercial development of new stainless steels. As such, it is the APERAM reference Research Center in terms of stainless steel metallurgy, their in-use properties and their manufacturing processes as flat products.

The Process R&D team is responsible for providing technical support to production plants in order to optimize process routes to meet productivity, quality, capability, energy and environmental needs. It also feeds the Innovation Process processus in order to offer disruptive solutions to prepare the manufacturing processes of tomorrow. As part of this activity, a regular presence on the production sites is to be ensured in order to collaborate with the local teams and to deepen the understanding of the manufacturing processes.

APERAM is highly committed to the transformation of stainless steel production in relation to environmental and economical / competition challenges. APERAM is the first stainless steel producer to obtain the Responsible Steel label. Very ambitious targets have been defined to reduce CO2 emissions, water consumption and waste landfilling in the coming years via, for a part, a strategic optimization of the industrial facilities. The proposed position will be part of the team dedicated to downstream process.This will go through the development of a very close network with industrial teams and CTO organization to develop key competencies in link with following thematics: Surface quality of cold rolled stainless steel, mechanics of cold rolling: flatness management, thickness capability and regulation, cold rolling strategy. Parallel thematics related to tribology / lubrication could also be included.

Missions

Within the Process team, you will be required to:

• Be regularly present in APERAM plants (located in Gueugnon, Isbergues, Genk and Châtelet)
  • Presence on site (estimated ~20%)

  • Development of new models, improvement of existing ones
• Surface Quality - Hot & Cold rolling related defectology
  • Participation in the resolution of defects finding their origin in the hot and cold rolling process (identification of mechanism, proposition of improvements & industrial trials, …)
• Cold rolling strategy
  • How rolling strategies are defined (number of passes, reduction rate, roll change practices, speed, …)
  • Impact of rolling parameters on final products (surface quality, metallurgical state, flatness…)
  • Is there a way of progression ?
• APERAM Footprint - Optimisation of process route and existing tools
  • Support in the transfer of products from the industrialization of new process route
  • Support for new Cold Rolling process design
