Embodiment 1

[0039] The dry laterite, reduced coal and sulfur are fed into the melting furnace through the material inlet 11, and the mixed gas composed of oxygen and natural gas is sprayed into the molten pool from the vent hole 13 by the side-blown lance, and the lance is immersed in the melt. The dry laterite ore completes ore melting, nickel-iron reduction reaction and nickel and iron sulfidation reaction in the smelting reduction sulfide zone 25 . A large amount of flue gas formed by the oxygen and natural gas injected by the side-blowing lance during the combustion process forms a violent agitation on the melt, and the nickel and iron metals in the melt are fully reduced and vulcanized under the action of the kiln chopping 23 installed at the bottom of the molten pool , and can promote the effective separation of slag and low-nickel matte mixed melt. The low-nickel matte is discharged from the product outlet 21, and the waste residue is discharged from the waste residue outlet 22.

Abstract

The invention discloses side-blown smelting equipment, which includes a furnace body and a base, wherein a material inlet and an air outlet are arranged at the top of the furnace body; the base is mounted at the bottom end of the furnace body; a waste residue outlet and a product outlet are arranged on the base; a vent hole for ventilating the interior of the furnace body is arranged at the side part of the furnace body; and the base accommodates the material to be reacted and discharges the reaction product and waste residue. According to the side-blown smelting equipment of the invention embodiment, by adopting the vent hole at the side part of the furnace body for ventilating the interior of the furnace body, the material entering the material inlet can be sufficiently blended and mixed, thereby saving the process of otherwise blending, improving the reaction efficiency of the smelting reaction, and reducing the energy consumption.

Description

technical field [0001] The invention relates to the technical field of metal smelting, and more specifically, the invention relates to a side blowing smelting equipment. Background technique [0002] Nickel has the characteristics of anti-oxidation, anti-corrosion, high temperature resistance, high strength, good ductility, etc. It has a wide range of uses, especially in the iron and steel and non-ferrous metal smelting industry. The proportion of consumption is the largest, followed by light industry, machinery manufacturing, chemical industry , petroleum and electric power industries, and the demand for nickel in high-tech fields is also very strong. [0003] The world's land-based nickel reserves are about 41.7 billion tons, 39.14% of which exist in the form of sulfide ores, while about 70% of the world's nickel is extracted from sulfide ores, and nickel in oxide deposits accounts for 60.16% of nickel reserves. With the depletion of economically available nickel sulfide ...
