Oxygen-enriched molten pool melting furnace

Abstract

The invention discloses an oxygen-enriched molten pool melting furnace which comprises a furnace body (1) with a furnace cavity; the furnace body (1) is composed of an upper part furnace wall (101), a lower part furnace wall (102) and a furnace bottom (103); the upper part furnace wall (101) is a furnace shell steel plate; the lower part furnace wall (102) is a water cooling jacket which is of a hollow structure; a U-shaped refractory concrete liner (2) is arranged on the inner side of the lower part furnace wall (102); a high alumina brick heat insulation layer (3) is built on the inner side of the upper part furnace wall (101); and a magnesia-chrome brick heat insulation layer (4) is built in the furnace cavity of the furnace body (1) on the inner sides of the U-shaped refractory concrete liner (2) and the high alumina brick heat insulation layer (3). The oxygen-enriched molten pool melting furnace can prevent a melt from leaking, protects the water cooling jacket, saves energy and is environmental friendly.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to an oxygen-enriched molten pool melting furnace. Background technique [0002] Oxygen-enriched molten pool melting furnace is mainly used to process various non-ferrous metal materials, such as materials containing copper, lead, zinc, nickel, tin, bismuth, indium and gold and silver. [0003] The existing molten pool melting furnace generally adopts the structure with water jackets on the upper and lower sides, and most of the inner linings only use refractory bricks, and some even directly contact the water jacket with the high-temperature melt. Such molten pool melting furnace mainly has the following two problems: (1) Only refractory bricks are installed in the melting furnace, and the refractory bricks are easily corroded after long-term high-temperature smelting, causing the water jacket to be easily damaged, and the melt in the furnace body Leakage is prone ...

AI Technical Summary

Problems solved by technology

Such molten pool melting furnace mainly has the following two problems: (1) Only refractory bricks are installed in the melting furnace, and the refractory bricks are easily corroded after long-term high-temperature smelting, causing the water jacket to be easily damaged, and the melt in the furnace body Leakage is prone to occur; (2) The upper and lower parts of the molten pool melting furnace adopt the structure of water jacket, which consumes a lot of water, and the furnace body relies on the water jacket to cool the energy loss.
