- W2787694517 abstract "Bottom blown copper smelting furnace (BBF) in Dongying Fangyuan Nonferrous Metals Co. Ltd has been operated for more than 6 years. This new technology has shown a number of advantages comparing to other copper smelting technologies. Long service life of the refractories is one of the advantages resulted from low-temperature operation. Analyses of the BBF slags have shown that BBF was continuously operated at temperatures below the slag liquidus and spinel is always present in the slag. As the first commercial BBF limited information is available for the deposits present in the BBF. Presence of the accretions can generally protect the refractories. However, extensive accretions could significantly reduce the effective volume of the smelting furnace and also fluid dynamic conditions of the bath. It is important to maintain proper accretions to the optimum level. A large number of accretion samples inside the BBF were taken from different locations during the annual maintenance. The samples were sectioned, mounted and analysed using Electron probe micro-analysis (EPMA). The phases present and their compositions have been identified and summarised in the present study. Formation mechanisms of the accretions are discussed in the present investigations. The present study will help the operators to properly control the accretions in bottom blown copper smelting furnace." @default.
