Corrosion of MgO-C with Magnesium Aluminate Spinel Addition in A Steel Casting Simulator
Ceramics, 2020 For more than 20 years, the sidewalls and bottom of steel ladles have been lined with carbon-bonded magnesia (MgO-C) and magnesia-alumina bricks (MAC). The alumina raw materials react with magnesia forming a spinel, which decreases open porosity and slag

The Influence of Surface Finish on the Localized Dissipation of Frictional Power at Ultra-Mild Wear [PDF]
, 2015 Tribological systems are subjected to a steady decrease of friction and wear due to ecological and economical requirements. These guidelines can change the tribological loads and, therefore, result in more severe conditions. The need for maintaining wear

Journal of Physics: Conference Series, 2020 Abstract The 18CrNiMo7-6 steel billet was prepared by the process of EBT→LF→VD→die casting and forging. The position distribution, composition, type and cause of inclusions in the billet were statistically analysed by ASPEX and scanning electron microscopy. The results show that there are obvious distribution differences of inclusions in
