Molten pool smelting converter with antimony ore bottom blowing and top blowing mixed

Abstract

The invention discloses a molten pool smelting converter with antimony ore bottom blowing and top blowing mixed. The molten pool smelting converter comprises a horizontal barrel-shaped converter body.The converter body comprises a converter body shell and a converter cavity arranged in the converter body shell. A refractory material is arranged between the converter body shell and the converter cavity. A walking gear used for controlling rotating is arranged at one end of the converter body shell, and a driven rotating gear is arranged at the other end of the converter body shell. A feeding opening is formed in the side face or one end face of the converter body shell, and a smoke discharge opening is formed in the other end face of the converter body shell and is in noncontact connectionwith a flue. One or more bottom blowing air holes and one or more top blowing inserting holes are formed in the converter body shell. The bottom blowing air holes and the top blowing inserting holespenetrate through the converter body shell and the refractory material to communicate with the interior of the converter cavity. According to the technical scheme, productivity can be effectively improved, energy consumption can be reduced, economic technology indexes can be improved, and production cost can be reduced.

Description

technical field [0001] The invention relates to a bottom-blowing and top-blowing mixed bath smelting converter for antimony ore. Background technique [0002] Traditional antimony ore rough smelting processes are popularly applied in three processes: vertical shaft furnace volatilization roasting, open hearth bottom blowing volatilization roasting, and blast furnace volatilization smelting. Among them, vertical shaft furnace volatilization roasting and open hearth bottom blowing volatilization roasting are adopted by the state due to low production capacity and high labor intensity. Listed as eliminating backward production capacity. The traditional antimony ore rough smelting process is now mainly antimony blast furnace volatilization smelting process. The specific plan is to mix the fine ore into balls and lump ore together with coke, iron ore, limestone, etc. in appropriate proportions, and classify and batch from the top of the furnace. The warehouse is put into the fur...

Problems solved by technology

However, the blast furnace volatilization smelting process has high energy consumption and tail gas SO 2 The concentration is too low to make acid, and the economic benefits are not ideal. There has been almost no technological upgrading and progress in the development for half a century, which seriously restricts the development of the industry. Compared with other non-ferrous metal smelting new technologies, it has gradually fallen behind. There is a gap in energy saving and emission reduction process requirements
