Novel double-chamber furnace for aluminum and aluminium alloy casting

Abstract

The invention discloses a novel double-chamber furnace for aluminum and aluminium alloy casting. The novel double-chamber furnace comprises a furnace body, a first burner and a second burner. The second burner and the first burner are arranged on the two sides of the furnace body, a first chamber and a second chamber are formed in the furnace body, the second chamber and the first chamber are connected with a shared furnace wall, a molten aluminum flow passageway is formed in the shared furnace wall, one end of the molten aluminum flow passageway communicates with the first chamber, and the other end of the molten aluminum flow passageway communicates with the second chamber. The first chamber is connected with the first burner, and the second chamber is connected with the second burner. According to the novel double-chamber furnace for aluminum and aluminium alloy casting of the structure, an overflow port is formed, easy-to-thin walls, scattered waste and iron-containing materials can be simultaneously smelted, iron can be recovered, energy is saved, immersed melting is achieved, metal losses are reduced, the production efficiency is improved, meawnhile, the structure is simple,and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of smelting furnaces, in particular to a novel double-chamber furnace for melting and casting aluminum and aluminum alloys. Background technique [0002] At present, my country's industry is developing rapidly, and industry plays an important role in the development of my country's economy. At present, double-chamber recycled aluminum melting furnaces are widely used in smelting equipment, because the melting point of commonly used aluminum alloys is not high, and there are basically two types of melting furnaces. : Crucible type and molten pool type. Crucible furnace is a common equipment for smelting recycled aluminum alloys. Its advantages are low investment, convenient operation and high metal recovery rate, but its disadvantages are small production capacity, short life and unstable composition, which is difficult to compare with melting pools. However, the function of the existing smelting pool is rela...

AI Technical Summary

Problems solved by technology

The crucible furnace is a common equipment for smelting secondary aluminum alloys. Its advantages are low investment, convenient operation and high metal recovery rate, but its disadvantages are small production capacity, short life and unstable composition. It is difficult to compare with melting pools.

However, the function of the existing smelting pool is relatively single. It can only smelt easily oxidized materials or only smelt iron-containing materials. These two materials cannot be smelted at the same time, and there are problems such as waste of materials and incomplete smelting.

In addition, the existing double-chamber furnace is equipped with a mechanical side well, which can achieve the exchange cycle of aluminum soup in the two molten pools through a mechanical pump, and the communication channel is at the bottom of the molten pool, which is easily blocked by molten slag and is not easy to clean. They are all relatively high, and have high requirements on the quality of raw materials. They cannot melt ferrous materials, and it is not easy to clean the furnace and slag, etc.
