Typically a bus bar system for a modern smelter is made of aluminium, weighs 15,000t and costs $50m. As such it represents 10-15% of the potline cost. With increasing amperage the bus bar complexity must also increase in order to avoid high magnetic field
Anode stud bars are custom-made in accordance with the customers specification. Various steel grades as requested. HMR has been supplying these commodities to the aluminium smelters for over 25 years. Exclusive network of the international sub-suppliers
For the iron carbon chemistry of a typical ultra-low carbon (ULC) cathode collector bar of around 0.06% max carbon, there are 2 distinct phases of the iron structure: Ferrite/Pearlite and ...
Abstract A nite element model of a cathode assembly including a copper insert inside the steel collec-tor bar was developed. This thermo-electro-mechanical model includes interfaces to simulate the contact between di erent materials. In order to optimize this

Title Analysis of the current distribution in an aluminum electrolysis cell with copper collector-bar cathode assembly Author(s) Das, Subrat Morsi, Yos Brooks, Geoffrey Conference name Australasian Aluminium Smelting Technology Conference (10th : 2011
Carbone Savoie offers different grades and shapes of electrolysis pot sides. Our preformed sidewalls and preshaped sidewalls adapt to the various thermal conductivity requirements of aluminium plants, thus enabling us to optimise the thermal balance of the reduction pot and ensure the right depth of aluminium pot bath.

CHEMICAL AND PHYSICAL CHANGES OF CATHODE CARBON BY ALUMINIUM ELECTROLYSIS 779 3 materials, graphitic, semi-graphitic and anthracitic. Figure 7 shows sodium expansion in laboratory-made materials where petroleum coke with different heat
Alumina is added to the cell periodically because during the electrolysis its concentration drops, and if it is allowed to fall below about 2%, the electrolysis cell undergoes a sudden and major operational failure known as an `anode effect'.
In this work, the current distribution in an aluminium electrolysis cell with copper collector-bar was predicted using finite element modelling. A 2D cross-section of a commercial cell was used under steady conditions of electrical fields in anode, electrolyte, molten
Impact of using selective collector bar rodding on the MHD stability of a 500 kA aluminium electrolysis cell
15/5/2001· A cathode collector bar having a top side, a bottom side, and a longitudinal axis is positioned in electrically conductive contact with the cathode block and extends from outside the first cell wall to within the cell, in one aspect to at least near the cell center.
