Submerged arc furnace with discharged material uniformizing effect

Abstract

The invention discloses a submerged arc furnace with a discharged material uniformizing effect. The submerged arc furnace comprises a furnace body (1), feeding ports (12) are formed in the upper end of the furnace body (1), iron outlets (2) are formed in the side wall of the lower part of the furnace body (1), the several feeding ports (12) are provided and are uniformly formed, the number of theiron outlets is two, the bottom surface (11) of the furnace body (1) is an inward-concave conical shape, moreover, the joint between the bottom surface (11) and the side wall of the furnace body (1) is inclined towards one sides of the iron outlets (2). According to the submerged arc furnace, the feeding ports (12) are formed in the upper end of the furnace body (1) in an annular shape, and are connected with feeding pipes correspondingly, so that materials are uniformly distributed in the furnace body (1), then the problem of material segregation in a single feeding mode is effectively solved; meanwhile, the number of the iron outlets (2) is two, one iron outlet is used, one iron outlet is standby, the two iron outlet can be used in a staggered mode, so that the service lives of the ironoutlets are prolonged; and meanwhile, the bottom surface (11) is arranged to be the conical surface so that a molten-state crude product can flow out along the bottom surface (11) inclining towards the iron outlets (2), and discharging is facilitated.

Description

technical field [0001] The invention discloses a submerged arc furnace with equally distributed discharge, which belongs to the field of industrial metallurgy. Background technique [0002] Submerged arc furnace is also called electric arc furnace or resistance electric furnace. It is mainly used for reducing smelting ores, carbonaceous reducing agents and solvents and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochromium, ferrotungsten, silicon-manganese alloy and other ferroalloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide. [0003] The submerged arc furnace is an industrial electric furnace that consumes a lot of power. It mainly consists of furnace body, furnace lining, short net, water cooling system, smoke exhaust system, dust removal system, electrode shell, electrode pressing and lifting system, loading and unloading system, gripper, burner, hydraulic s...

AI Technical Summary

Problems solved by technology

[0004] The submerged arc furnace in the prior art has a single feed port, which makes the material segregation more serious, resulting in uneven temperature in the furnace body and easy damage
