Dynamic Process Optimization (DPO) in Anode Plants

The 'Dynamic Process Optimization' (DPO) is a quick approach allowing to vary all important anode paste plants parameters within hours. In the mobile laboratory the paste samples are formed and baked.
Analysis of the baked samples in RDC's laboratory allows determining exactly the optimum set of parameters for the green anode production.

Review of Anode Behaviour in Smelters

In linking anode behavior to anode properties RDC is able to pinpoint the causes of substandard anode behavior and to recommend appropriate counter measures.

Third party support in anode and cathode production and quality certifications for export

Up to now, RDC supported Aminco, a US based anode supplier with the production of more than 2.000.000 tons of anodes from Chinese producers in order to permanently fulfill the the quality standards of customers in North America, Europe, Middle East, Australia and Asia.

RDC also monitors the quality of cathode blocks on request from suppliers or as arbitrage at smelters.
