15 Early Stage Researchers wanted for ATHOR!

Image recherchePartner of the ATHOR network, Imerys Refractory Minerals underlines its concern about the future of the refractory industry. Indeed, we measure the importance of cross-disciplinary approaches which will dramatically increase the transfer of scientific knowledge to our refractory-consuming industries in Europe ensuring progress on social, environmental and economic aspects.

ATHOR stands for advanced thermo mechanical multiscale modeling of refractory linings. This innovative, collaborative and interdisciplinary project is dedicated to train Early Stage Researchers (ESRs) in multi engineering fields for a better understanding of thermo mechanical behavior of refractory linings used in iron and steelmaking. The main objective is to develop high-end engineering technologies in material engineering and numerical simulations thanks to an intensive cooperation between academia, raw materials suppliers, refractory producers and end-users.

A 4 year European Training Network program will start in October 2017 as a Marie-Sklodowska-Curie action and will allow 15 committed and highly motivated Early Stage Researchers to craft the future of ceramic materials for high temperature applications.

With 14 international partners, including 8 industrial companies (Altéo Alumina, Imerys Refractory Minerals, Magnesita Refractories, Pyrotek Scandinavia AB, RHI AG, Saint-Gobain, Tata Steel, FIRE) and 6 universities, these young researchers will have the opportunity to collaborate with experts in various research groups and may take advantage of the most sophisticated numerical tools to model, design and predict the life of refractory lining configurations in critical operation conditions.

Trained in scientific, technical and soft skills, the 15 ESRs selected in the program will be the next generation of highly employable scientists and engineers in the refractory industry and related areas. These future PhD will bring the necessary answers to the primary challenges for both the European Steel and Refractory manufacturers linked to cost and availability of raw materials and energy, as well as to environmental and climate change regulation.

Metakaolin: its potential in geopolymers

Virginie Soleil - buste gauche - 04 2017Virginie Soleil-Raynaut, Imerys Refractory Minerals’ ground and calcined clays product manager will review on “Metakaolin: its potential in geopolymers” at the occasion of the 2017 GeopolymerCamp.

Metakaolin is an amorphous state of kaolinite which is obtained by firing a kaolinitic clay at a temperature between 700 and 950°C. Thanks to its pozzolanic behavior and its fine particle size, this category of functional fillers is used in many applications.

Based in French Picardie, the Geopolymer Institute has been organizing the annual GeopolymerCamp since 2009.

The 2017 edition will take place from 10th to 12th July at the University of Picardie, 48 rue d’Ostende, 02100 Saint-Quentin, France. This event is an ad-hoc gathering born from the desire to share and learn in an open environment.

This camp is neither a conference, nor a congress. It is a casual, informal meeting between anyone who has something to share in the field of geopolymers, and anyone with the desire to learn, to interact, and to network.

Students, scientists, researchers, engineers from public and private organizations, curious or long-term experienced people in their fields of expertise, professionals involved in a wide range of development, including managers, finance specialists, R&D, marketing, business decision makers, technology and products development specialists.

Kerphalite™ KF : moulding material for precision casting

Casting, Plant & Technologie, December2016

Casting, Plant & Technology, December 2016

In its December edition Casting, Plant and Technology International  published the following article about the key role of Kerphalite KF for precision casting written by Joachim Wolff (Imerys Refractory Minerals), Sabine Umla-Latz and Martine Dahlmann (Hüttenes-Albertus).

Complex cast parts such as turbocharger housings play a central role in the design of modern high-performance engines. Due to its particular characteristics, silica sand has its limits as a moulding material when it comes to casting finely structured components, reduced wall thicknesses and perfect surfaces. Thanks to its high temperature load strength and a strong resistance to metal penetration, Kerphalite™ KF, a special sand produced in Brittany for special applications in the foundry industry, has proven itself suitable for these types of applications in many foundries.

In central Europe, silica sand is available in large quantities and in good qualities, and is widely used in foundries as an economical basic moulding material. But it also has negative properties, which may lead to problems when producing sophisticated castings. These particularly include the so-called quartz inversion, i.e. the abrupt expansion of the specific volume at 573°C. It occurs during virtually every casting process and may lead to sand expansion defects, mainly in the form of finning (also called veining). The moulding material can crack under high temperature load, allowing liquid metal to seep into the resulting cracks and cavities.

Community project restores dignity to girls

community-project-restores-dignity-to-girls

Since several  years, Imerys Refractory Minerals implements education programs, supports agricultural cooperatives and modernizes infrastructures to improve life standards of its employee’s communities.

Late 2015 Imerys South Africa started partnership with The Peace Agency  to fund  locally produced Subz Pads packs of washable sanitary pads and underwear to fight against absenteeism and drop-outs of girls in high school living close to Imerys Annesley mine in the Limpopo province. It appears that 60 %+ of girls in South Africa miss 18 months (out of 5 years) of high school due to not having access to sanitary products.

Xolisa Mvinjelwa, Executive Director for Ethics & Transformation, explains “The villages around our mine are made up of poor communities with high unemployment and low levels of education. Families depend on grants and parents are unable to afford these sanitary pads.”

the-peace-agencyThis action is beneficial to both, Imerys employees and the girls. Together with NGO representatives, Imerys employees distribute these reusable pads and take the occasion to talk to the girls about health and hygiene issues during their visits, thus tying bonds.

In 2016 the initiative was repeated and extended to other schools. Schools’ principals and staff observe a lower rate of absenteeism and drop-outs. Furthermore they feel that the girls have more confidence in themselves which enhances the level of creativity in the classroom.

New Face Coat Material for Investment Casting Molds

Imerys Refractory Minerals for foundry applications in collaboration with CARRD, Imerys R&D center for refractories & abrasives, developed a new solution for face coat material.

The Treibacher Alodur WRG IC ESR , a synthetic material  based on fused alumina, is the ideal alternative to zircon for face coat applications.

Our solution was introduced during WCIC, World Conference of Investment Casting held in Paris in April 2016 by Dr Thomas Krumrei , CARRD R&D engineer and expert of Investment Casting technology.

incast-2016-march-editionModified Fused Alumina, Treibacher Alodur WRG IC ESR: A New Generation of Products
Specially modified fused alumina (WRG IC ESR) exhibits outstanding properties, when it comes to heat resistance and chemical stability. These properties allow casters to avoid vitrification and migration of alloying elements into the ceramic mold. Furthermore, its high heat and deformation resistance is one key element to producing castings with extremely tight tolerances (for e.g. turbo charger wheels).

Another key advantage of modified fused alumina is its excellent compatibility with standard Na-stabilized binders. Even after 10 months test-runs, slurries show no signs of changes in optical, pH, or viscosity values.

The lack of natural impurities and variations, especially in face coat materials is definitely one of the biggest advantages of this new primary coat generation. Use of this material allows for irregular appearance of defects in castings to be reduced to a minimum….

1st Imerys Refractory Minerals Safety Day

First Imerys Refractory Minerals Safety Day

At Imerys Refractory Minerals just as throughout the Imerys group, safety is our number one priority. Imerys develops a proactive safety and health culture by implementing the three pillars of the Imerys Safety System: compliance, continuous improvement and communication. It is structured along the following lines: clearly defined audit protocols, regular audits, a global training plan, safety training based on a behavior-based model, an accident analysis program and a serious accident prevention plan, as well as events designed to strengthen safety culture.

Over the past years, various actions were taken to modernize production sites and machinery, and important means were put on improvement of security awareness throughout the Imerys Refractory Minerals staff. Whether high or medium level managers or workers on the production sites in France, the UK, the USA, South Africa and China, everybody took action for best security within the division.

November 24th was 2016 Safety Day at Imerys Refractory Minerals. Each production site interrupted its activity for half a day bringing together local staffs to strengthen safety awareness. Time was dedicated to align with the division safety targets, actions and results. Teams were given the opportunity to discuss their local security approach and behavior change thanks to the “Take 5” program for example. “Take 5” is a pre-task risk assessment and reduction tool helping drive safety awareness to all employees. It was launched in 2014. Early this year “Serious7” went life. It is a new protocol  for forklift safety helping site managers to review specific issues such as technical deficiencies or regular maintenance matters.
