LIFE 4 Green Steel
Objectives and results
The project specific objectives are:
- develop an effective pressing system integrating DWL, to produce sintered steel parts having density greater than 7.3 g/cc and high dimensional stability
- develop a reliable case hardened profile of PM steel via LPC
- use a steel chemical composition avoiding harmful alloying elements (e.g nickel) or alloying elements which make the following recycling step difficult and ineffective (e.g. copper)
These will lead to environmental objectives like:
- guarantee energy and material saving through innovative HDPM, whose peculiarity is primarily its netshape capabilities and very high material use coefficient (95%) which minimize the energy inputs (machining determines a material use coefficient of 50% and generates environmental problems regarding the pollutant cutting fluid);
- strong reduction (more than 70%) of lubricant premixed with the metal powder (standard 0.8wt%) eliminating the burning stage, increasing the energy efficiency and solving the related emission problem
- High energy savings during producing and recycling (-50%)
- High raw material savings (-47%)
- Strong reduction in use of admixed lubricants (-70%) and fluid lubricants (-100%)
- Strong reduction in emissions related to lubricants (-70%)
- Strong reduction in CO2 emissions (-100%)
Activities to be done:
- Study, design and development of a compaction press able to operate with the die wall lubrication system (DWL);
- Definition, design and manufacturing of an effective DWL deposition system;
- Study and evaluation of an efficient lubricant able to be deposited by DWL system;
- Design and manufacturing of simple and complex dies for the experimentations;
- Powder metallurgy alloy design, for steels without nickel and copper elements;
- Compaction Stage Tuning;
- Study and optimization of vacuum sintering conditions;
- Characterization of Sintered products;
- Study and design of effective case hardening profile via Low Pressure Carburizing (LPC);
- Software development for LPC process simulation;
- Characterization of Case Hardened component;
- Life Cycle Assessment;
- Dissemination and Networking.
The project started on July 1,2017 and will have an estimated duration of 3 years.
The actions undertaken to date mainly concern the management aspects of the project, as well as the start of the first technical phases.
The project partners have established a management team and identified the strategic plans and practices to be implemented in order to achieve the expected results.
From a technical point of view, the partners have started work on the study of lubricants, lubrication methods, study of mold material, press specifications and the first activities of the design and construction of the press integrating the Die Wall Lubrication system.
As far as dissemination activities are concerned, the team realized the notice boards and the first paper-based dissemination materials, as well as this new section of the website dedicated to the LIFE project.
LIFE is the EU’s financial instrument supporting environmental, nature conservation and climate action projects throughout the EU. Since 1992, LIFE has co-financed more than 4500 projects. For the 2014-2020 funding period, LIFE will contribute approximately €3.4 billion to the protection of the environment and climate.
The European Commission (DG Environment and DG Climate Action) manages the LIFE programme. The Commission has delegated the implementation of many components of the LIFE programme to the Executive Agency for Small and Medium-sized Enterprises (EASME). External selection, monitoring and communication teams provide assistance to the Commission and EASME.
