CONTROLLING THE PROCESSING PARAMETERS AFFECTING THE REFRACTORY REQUIREMENTS FOR PEIRCE-SMITH CONVERTERS AND ANODE REFINING VESSELS

摘要

Refractory linings in converters or anode furnaces used to over-oxidize the blister copper will suffer rapid deterioration, due to prolonged contact with copper oxide-rich slag. Nitrogen stirring with COP KIN~® porous plugs and use of SEMTECHOPC in converters and anode refining vessels can considerably reduce both refractory wear and processing times. In addition, careful control of the vessel atmosphere and the use of real-time optical process control minimize both slag volume and contact time with the vessel refractory.
