Abstract

Vanukov Furnace No. 2 was placed in operation in 2009, within reconstruction of metallurgical complex, located on the site of JSC “Sredneuralsky Copper Smelter”, which allowed to increase the blister copper output by 1,5 times. Along with application of new production modes, there was realized the program of modernization and re-equipment measures, focused on further improvement of metallurgical complex operation. In this regard, in the period from 2010 till 2013, there were realized the measures, aimed on provision of rhythmic unloading of feedstock and extending of storage facilities. At the same time, new hangar was built and placed in operation for defrosting of incoming stock during cold autumn-winter period. Capacity of this hangar was 2500 t of copper concentrate per day. Construction of new sections in storage house for provision of additional storage area for main copper concentrates is carried out. Improvement of charge preparation quality is achieved by means of separate hopper feeding of components. Installation of modern weighting hoppers increased the material dosing accuracy for melting furnaces. Automatic sampling facilities were designed and installed for the purpose of controlling of chemical composition and humidity level of charging material. Range of measures, directed to modernization of water-cooling elements and furnace baffles, is realized, and more resistive refractory materials are selected. All the foregoing leads to improvement of reliability of melting furnaces and to extension of inter-maintenance period. System of evacuation for process and aspiration gases from melting facilities is improved. Melting and converting modes (using matte, containing 52–56% of copper) are worked out to increase copper smelting shop productivity.
