The laterite-nickel ore smelting technology in the blast furnace has high requirements on raw material grade, pellets are required to be sintered, and the environmental pollution is serious, so the process is basically in a phase of elimination. At present, the RKEF smelting process is adopted by most enterprises at home and abroad. However, the RKEF smelting process has the defect that the cobalt in the nickel ore can not be recovered, and is not suitable for the nickel oxide ore with higher cobalt. In addition, the process is relatively energy-consuming, and requires abundant local power. Many lagging islands in overseas do not have power supply systems, thermal power stations need to be established, the investment cost is high, and the method is suitable for large-scale ferronickel smelting enterprises.
In order to solve the problem that a laterite-nickel ore smelting plant is built in a place where cobalt content is high and nickel content is low in laterite-nickel ore or power resources do not meet conditions in the prior art, a process technology for smelting laterite-nickel ore by side-blown combustion is developed by the research and development of certain national metallurgical design institute. The technical scheme includes that furnace burden is added into a hearth from a furnace top feeding port and falls into a strongly-stirred melt, the melt is stirred by blowing high-pressure oxygen-enriched air and coal powder into a slag layer through a multi-gun nozzle located on the side face of a furnace body, the melt is strongly stirred in a bubbling area higher than a lower-row nozzle, the physical and chemical reaction is completed through combustion reduction of the coal powder, slag and iron are settled and separated under the action of gravity in reduction production of slag nickel molten iron, the slag is discharged through a slag discharging port, and the molten iron is discharged through an iron port to form a pouring surface nickel-iron block.
However, the process generally has the main problems that the temperature of the laterite nickel ore smelting furnace hearth reaches 1400-. Frequent shutdown and excessive maintenance cost lead the process to be difficult to popularize. Many small and medium-sized smelting enterprises can only quench thirst with the plum.
