ALAFAR 2018 : And the winner is…..

The refractory world converged in Medellin, Columbia for the 41st annual congress of the Latin American Association of Refractory Manufacturers better known as ALAFAR in early October, with the ambition to look at “Innovation in High Temperatures” and it is a great honor for Imerys Aluminates that our Technical Director for Refractories, Christoph Wöhrmeyer has taken a podium position from over 30 technical presentations.

Christoph presented our joint research study entitled “Protection mechanism of CMA-additive in MgO-C ladle bricks”. It was undertaken together with S.Gao, S. Graddick, C. Parr, F.Simonin, G. Bhattacharya from Imerys Aluminates, with M. Liyama, Senior Technical Advisor Refractories at Imerys High Resistance Minerals in Japan and P. Gehre and C. Aneziris from the Technische Universität Bergakademie Freiberg.

The study investigates the effect of the addition of Calcium Magnesium Aluminate (trade name MagArmour) to Magnesia-Carbon (MgO-C) bricks. MagArmour™ consists of grains in which microcrystalline MA-spinel phases are embedded in a matrix of calcium aluminates. Applied as a binder in steel ladle castables it has already proven its positive effect on wear resistance in many steel plants due to the associated change in microstructure. The effect of MagArmour™ addition to MgO-C bricks in comparison to the addition of pure spinel has been investigated in the first part of this study. The MagArmour™ -doped MgO-C brick showed the lowest attack by slag. Following this positive result, several trials in different steel plants have been conducted and results from post-mortem analyses are discussed in the second part of this paper. All ladle trials had in common that during operations a slag coating was formed on the surface of the MagArmour™ containing bricks that reduced the wear rate of the bricks and gave a better protection of the carbon in the brick against oxidation. A lower wear rate was achieved, even when reducing the amount of anti-oxidants in the bricks.

Need more out of your light-weight aggregate? MULCOA® 43LW

From power generation to cement cyclones and coolers, steel ladle covers to petrochemical plants, the balance between minimizing energy loss while maintaining high strength and volume stability in applications above 1300C inevitably means making a tradeoff between a two component lining or accepting high heat losses.  Traditional light-weight materials based on vermiculite, cenospheres or other light-weight aggregates typically suffer from needing high cement contents and high water demand to allow for good casting properties. The trade-off is extreme shrinkage when put in use above 1300C or alternatively very poor wear resistance, forcing alternative solutions that are not optimized for thermal efficiency.

Can you imagine a light weight aggregate that allows you to produce a range of castable formulations that can have a similar ultimate refractoriness to the benchmark MULCOA® 47?

To understand the performance, the first step is to understand the production process of typical light weight aggregate. Density is linked to the true density and porosity of a material, so to create a light weight chamotte, you simply add pores. However, it is the internal structure of these pores that limit suitability for monolithic applications as they have a very high proportion of open porosity and this leads to large water demands and an aggregate and final product that typically low crushing strength.

Introducing MULCOA® 43LW, not just your average lightweight material. Using a proprietary industrial process, Imerys Aluminates are able to create a refractory aggregate that seals a high proportion of the open porosity leaving a high strength refractory aggregate that has an improved insulative behavior but is still suitable for a range of monolithic applications.

Capable of being used in low-cement castables, pumping grades, dry and wet gunning grades and high strength insulation grades and suitable for use in products rated to 1450C and beyond, MULCOA 43LW based castables maintain hot strengths compared to equivalent alumina products while lowering density, thermal conductivity and maintaining CO resistant behavior.

Offering the opportunity in specifically adapted castables to reduce surface temperatures and increase thermal efficiency, MULCOA® 43LW opens possible new lining concepts to better meet the changing needs of modern refractory applications giving refractory lining designers the chance to save time or reduce risk via new solutions.

Imerys Aluminates: Better Together!

Jean-Marc Bianchi Vice President & General Manager

Jean-Marc Bianchi – Vice President & General Manager

Today, the 2017 results for the Imerys Group have been commented on by Gilles Michel, our CEO, to the financial community. During this communication, he announced the creation of a new division resulting from the combination of the Refractory Minerals and Kerneos divisions: Imerys Aluminates!

In turn, I am pleased to announce the birth of our division, «Imerys Aluminates», one of the Group’s twelve divisions. Imerys Aluminates!


Firstly, it is under this name that the smart alignment I have been talking about over the past months will be achieved;
Secondly, under this name that we will, together, combine the skills of over 2,350 professionals;
Thirdly, under this name we will together strengthen our expertise, to better serve our customers and support our growth through geographic development and innovation.

Imerys Aluminates: It’s not only our name, it’s also a unified management frame that will drive and direct the legal entities forming Refractory Minerals and Kerneos, without changes to your employment conditions or contracts. Each
company therefore retains its legal autonomy, as is the usual case within Imerys Group divisions. A deployment plan for this new name is currently being prepared. It will be soon communicated to properly structure this change of identity and its impact on our various internal and external communications.

To conclude this short message, I wish to express once again my enthusiasm and my conviction that this combination of Imerys Refractory Minerals and Kerneos is a great opportunity for all of us and for our customers: we are complementary and together we will be even better !
