In part II of this article we focus on the joint development, as increasing potline currents and voltage ratings of smelting plants require high power rectifiers.
Modelling of the cathode block assembly using different types of newly developed collector bar super ramming pastes.
The 180 kA Trimet cell MHD-Valdis model is used in this modelling study.
Consistent fineness of fines in the anode dry aggregate is essential for good performance in aluminium smelting. The implementation of the RDC Blaine apparatus in the paste plant quality control system allows quantification of the progress made towards consistent fines.
Calculations on a full 3D cell show the importance of this coupling between thermal-electric and magneto-hydrodynamic effects in various fields.
Optimised recovery and recycling of spent potlining (SPL) is an opportunity for aluminium smelters to eliminate the risks with SPL.
Rectifiers and the aluminium industry developed conjointly, as increasing potline currents and voltage ratings of smelting plants require high power rectifiers.
ASCM systems with climb milling technology allow deeper and narrower slots in anodes used in aluminium smelters, improving efficiency and mechanical behaviour.
Vedanta Aluminium has announced a significant breakthrough in potlining design at its aluminium smelters.
Interview with Trimet Executive Board member Dr. Andreas Lützerath about the future challenges in areas such as demographics, digitalization and decarbonization.
