Uzbekistan Determining the effective viscosity of a carbon paste used ...
The Soderberg electrode is a continuously consumed smelting electrode used in the production process of materials such as ferroalloys. The material which makes up the electrode is composed of a carbon “paste” which is solid at room temperature but softens, flows and is finally baked with increasing temperature.
Uzbekistan History | Elkem Carbon Solutions | Elkem.com
The invention of Soderberg electrode. In 1919, Elkem patented Soderberg electrode, a self-baking electrode which revolutionized the smelting industry. The new Søderberg technology, allowed for a non-stop continuous smelting in submerged arc furnaces. The small furnaces at the time, depended on graphite electrodes and prebaked carbon electrodes ...

Uzbekistan Segregation of Carbon Paste in a Smelting Electrode
corresponding workshop in Edinburgh, in March 1988. Elkem apply carbon paste in the Stfderberg electrode for smelting furnaces. Typical conditions in the upper part of an electrode are shown in Fig. 1. Billets of solid paste (of diameter up to 1 m) are fed into the top of a cylindrical steel tube (of diameter up to 2 m). Heat

Uzbekistan Inert Anode - an overview | ScienceDirect Topics
Therefore, it is high energy and cost intensive and lead to greater emission of GHGs from electrolytic processes (anode production and smelting) (Table 8.5). According to Kvande and Drabløs (2014), replacement of carbon anodes with inert one may reduce the energy requirement and is cost effective.
Uzbekistan ELECTRODE MANAGEMENT – INVESTIGATION INTO SOFT BREAKS AT ...
In this case also, liquid paste was observed leaking through the casing holes below the contact clamp tip where casing was punctured. Paste level was measured and found minus 0.2mtr i.e. below the contact clamp top position. This time, it took 04 days to clear total leaked paste all around the electrode to switch on the
Uzbekistan Submerged-arc furnace for phosphorus production - Wikipedia
Process scheme. The Submerged-arc furnace for phosphorus production is a particular sub-type of electric arc furnace used to produce phosphorus and other products. Submerged arc furnaces are mainly used for the production of ferroalloys. The nomenclature submerged means that the furnace's electrodes are buried deep in the furnace burden.
