The specification of the oxygen bottom blowing smelting furnace is ø5 × 28 m,
which consists of two feed ports, fourteen oxygen injector, positions on the bottom
of the furnace, four lance on the top, one siphon, two slag tapping holes, and one
offgas outlet near each siphon mouth.
High lead slag is added to the reducing furnace from the offgas outlet.
The refractory brick life of the RSKS furnace is more than two years.
The schematic diagram of the RSKS furnace is shown in Fig. 2.
