General Description
Performing raw material or electrode evaluations under laboratory conditions is necessary in terms of time consumption and cost optimizations. For this purpose, the RDC-164 apparatus can be used for the calcination or baking of different materials under well-controlled laboratory conditions.
In the case of green coke, a vertical shaft kiln calcination can be simulated, or a specific calcination degree can be achieved for a semi-calcined coke. This furnace can also be used for the baking of green electrodes or electrodes produced at the bench scale (see RDC-161). Depending on the application, typical calcination and baking curves with given heat-up rates are already programmed, the goal being to reach typical calcination or baking temperature. Custom-made heating curves can also be implemented for research projects, such as simulating the impact of the final baking temperature on the electrode quality in well-controlled conditions or creating calibration curves for comparison with the real production (for instance, for evaluating the temperature distribution of a baking furnace).
Approximately 4 kg of green coke or ten electrode cores with a 50 mm diameter can be loaded in one batch. The electrode samples or the green coke bucket are surrounded by packing material to prevent any air oxidation. The equipment is supplied with a tar incinerator unit for fume treatment purposes.
When a greater quantity of material is needed, the RDC-167 furnace is an option instead of the RDC-164 furnace.
