Carbon Based Refractories

THE ROLE OF CARBON IN REFRACTORIES

Some of the scientific principles underlying the role of carbon and graphite in graphitic refractories are considered, with emphasis on the graphite phase. The highly anisotropic nature ofgraphite is a key factor in its ability to modify the properties of oxide refractories, resulting in the potential for anisotropy in the subsequent graphitic composite, depending upon the fabrication condition...

IMPROVED CARBON BONDED MGO MATERIALS AS SMART REFRACTORIES

Improved structures of MgO carbon bonded materials due to new binder systems and due to the application of electrical currents during operation have been achieved for advanced applications in the secondary metallurgy and during near net shape metal casting.

A Study on the Reaction between MgO Based Refractories and Slag -Towards the Development of Carbon-free Lining Material

RECYCLING PRACTICES OF SPENT MgO-C REFRACTORIES

The recycling options of spent MgO-C refractories from an electrical arc furnace (EAF) have been evaluated. The economic, quality of spent refractories and products made from it, the ease of implementation of a recycling practice and the interest of steel melt shops were considered. It was decided that the best option of most EAF shops would be to recycle spent MgO-C refractory as a foaming sla...

The Effect of Carbon Nanoparticles and Calcined Alumina on Mechanical Properties and Corrosion Resistance Behavior of the Magnesia Carbon Refractories

Nowadays, magnesia carbon refractories are very important for the iron and steel industries. It is due to their unique properties, such as low wet ability with melt iron and steel. Therefore, it is important to extend the life of the refractory. In this research, the effect of calcined alumina and nano carbon on mechanical strength and corrosion resistance against slag in magnesia carbon refrac...
