Direct irradiation heating type aluminum alloy smelting furnace

Abstract

The invention discloses a direct irradiation heating type aluminum alloy smelting furnace. The smelting furnace comprises a furnace body shell, a furnace body heat preservation layer, a crucible and the like, wherein a liquid outlet is formed in the bottom of the crucible and connected with the exterior of the furnace body shell, a liquid outlet plug is arranged at an outlet of the liquid outlet,a crucible lining is arranged at an opening in the top of the crucible, the crucible lining and a crucible outer wall bushing flexibly protect the crucible from inside to outside, a crucible lining flange is arranged on the crucible lining, the crucible lining flange fixes the crucible lining and is connected with the furnace body shell, a top cover shell is arranged at a top opening of the furnace body shell, a top cover outer cover is arranged at the top of the top cover shell, a top cover heat preservation layer is arranged in the top cover shell through a top cover heat preservation layerflange, and a heating system is arranged on the top cover heat preservation layer. According to the smelting furnace, aluminum alloy is subjected to radiation heating smelting through an infrared heating pipe at the top, the smelting furnace is suitable for rapid smelting of large aluminum alloy ingots, and compared with a traditional resistance heating smelting furnace and an electromagnetic induction smelting furnace, the smelting furnace has the advantages of being economical, clean and efficient.

Description

technical field [0001] The invention belongs to the technical field of metal melting, and in particular relates to a direct radiation heating type aluminum alloy melting furnace. Background technique [0002] With the rapid development of high-end manufacturing in recent years, the demand for high-performance aluminum alloys is also increasing. The total output of domestic aluminum alloys has increased rapidly from 8.68 million tons in 2013 to 12.35 million tons in 2019, an increase of 42.2%. The resulting demand for smelting of aluminum alloys also increased sharply. At the same time, with the further improvement of the country's energy-saving and environmental protection requirements for aluminum alloy production enterprises, such as "Energy Consumption Limits per Unit Product of Aluminum Alloy Building Profiles" GB 21351-2008 stipulates that the comprehensive energy consumption of furnace feed materials must be above the existing standards Reduced by 6.7% to 9.7%, etc., ...

Problems solved by technology

The electromagnetic induction heating melting furnace wraps the entire furnace body with induction coils, and the eddy current generated by conduction heats and melts the aluminum alloy in the furnace body. This heating method can make the heating temperature reach 900 ° C, but it has a great disadvantage: noise Large, large radiation, high energy consumption, serious environmental pollution, and physical damage to operators

[0004] 2. Traditional resistance wire heating

[0008] At present, there is no successful direct radiation heating aluminum alloy melting furnace in the world. In summary, the development of a set of economical, efficient and clean aluminum alloy melting equipment based on infrared radiation heating technology has important practical value and market prospects
