First prize winner
Jacques Poirier for his article “A review: influence of refractories on steel quality”, published in volume 112/4, 2015, article 410.
About the article
Steel makers have to propose steel grades with narrower composition ranges, lower guaranteed contents of certain residuals and controlled inclusion size distributions to obtain reproducible and well adapted service properties. These metallurgical results can only be reached by a strict control of elaboration processes and also of products used during steel making. In this context, refractory materials have a crucial impact at different levels:
- The control of solute elements such as carbon, sulphur, nitrogen, hydrogen, oxygen, …
- The prevention of non-metallic inclusions.
This paper reviews the effects of refractories on inclusionary cleanliness and quality of steel products. It mentions all the important developments that will limit the contribution of refractory products concerning oxide cleanliness, steel desulphurisation, Ca treatments of alumina de-oxidation inclusions, carbon pick up for ultra-low carbon steel, clogging phenomena and atmospheric oxidation, in conjunction with efforts of the metallurgists to produce clean steels.

Second prize winners (exaequo)
1. Abhilash, A. Ghosh and B.D.Pandey for their article “Bioleaching of low grade granitic chalcopyrite ore by hyperthermophiles: Elucidation of kinetics-mechanism”, volume 112/5, 2015, article 506.
About the article
This work was performed to out-sheen the previous works on low grade chalcopyrite ore elsewhere, wherein the microbial specificity and temperature were the factors that primarily were thought to be affecting the solubilization of copper from such low tenor and hard rock material. Mesophilic leaching using natural bacteria results in a passivating layer forms on the mineral surfaces that prevents further leaching.
The current work displayed the ability of a thermophilic pyritic sulfur degrading bacteria isolated from a coal mine dump to bioleach copper from a low grade Indian chalcopyrite ore (0.3% Cu). With its prevalent ability to preferentially attack pyrite (a major phase in the ore, 85% copper recovery was obtained using <50µm particles at 20% (w/w) pulp density, pH 2.0, 75oC. The copper dissolution was facilitated by iron(III) available in the leach liquor because of bacterial oxidation of pyrite present in the ore under acidic conditions, which was corroborated by the XRD phase identification and SEM studies.

2. Peng Hu, Hui Zhang, Minglin Wang, Miaoyong Zhu, Xingzhong Zhang, Yingyi Zhang and Zhengyan Zhang for their article “Application of a chamfered mold to improve corner defects of HSLA during slab continuous casting”, volume 112/1, 2015, article 104.
About the article
The transverse corner crack is one of the main quality problems in the slab surface during the continuous casting process of micro-alloyed steel. The slabs with these defects are cut off the corner off-line by flame which not only causes the waste of energy, materials, human resources and the increasing of storage area, but also made hot charge and hot delivery impossible and the energy consumption of the heating process increased dramatically. A chamfered mold and the supporting technology are developed for removing the transverse crack. In industrial tests, the defects have significantly been reduced more than 95% by using chamfered mold compared with those in the conventional mold.
About the group
The National Engineering Research Center of Continuous Casting Technology (NERC-CCT) was found in 1994, its predecessor was the continuous casting center of China Iron and Steel Research Institute. 59 technicians and developers in the center: 2 members of Chinese Academy of Engineering, 13 professors, 22 Senior Engineers. In addition, there are 30 postdoctoral, doctor candidates, postgraduate students and domestic iron and steel enterprise's additional studies in continuous casting center.
About the authors
Peng Hu: born in 1986. He is a doctoral candidate in metallurgy engineering in Northeast University and China iron and steel research institute. The aim of his doctoral thesis contributes to understanding of edge seam defect on hot rolling strip surface. The forming mechanism of this defect is researched by finite element method and physical thermal simulation. Then, the defect was improved by method of slab shape designing, and this method is verified on industrial rolling mill.
