Embodiment Construction

[0026] Such as Figure 1~3 As shown, an upper immersion heating and melting furnace of the present invention includes: a furnace body 1, a furnace cover 5, a heater 6, and an electric control cabinet.

[0027] The furnace wall of the furnace body 1 includes a three-layer structure, in which the inner layer structure 11 is an integrally cast refractory material, the middle layer structure 12 is an insulation brick, and the outer layer structure 13 is a fiberboard. Such a three-layer structure design not only improves the furnace body 1 Corrosion resistance also reduces heat loss. The inner cavity of the furnace includes three chambers: a feeding zone 2, a discharging zone 3, and a heating zone 4. Among them:

[0028] ——The feeding zone 2 and the discharging zone 3 are completely separated by a sealed baffle, the purpose is to prevent the temperature of the molten metal in the discharging zone from decreasing due to the mixing of the newly added material and the molten metal in the ...

Abstract

The invention discloses an upper part immersed heating and melting heat-preserving furnace, relates to a heating and melting heat-preserving furnace, and aims to provide an upper part immersed heating and melting heat-preserving furnace, which has the advantages of low energy consumption, high thermal conversion rate, safety and convenience in use and low failure rate. The upper part immersed heating and melting heat-preserving furnace comprises a furnace body, a furnace cover and a heater, wherein the inner cavity of the furnace body comprises a heating area, a feeding area and a discharging area; the feeding area and the discharging area are communicated with the heating area respectively; the furnace cover is embedded into the opening of the heating area; the top of the furnace cover is further provided with vertical through holes; the heater is embedded into the vertical through holes; the heating position of the heater extends into the inner cavity of the heating area.

Description

Technical field [0001] The invention relates to a heating and melting holding furnace, in particular to a heating and melting holding furnace mainly used for smelting low-melting non-ferrous metals and their alloys. Background technique [0002] The non-ferrous metal heating furnace is the core equipment for melting, heat preservation and purification of aluminum, zinc and their alloys in the hot-dip plating and die-casting industries. Its annual consumption of aluminum and zinc account for 35% and 50% of the total domestic consumption of aluminum and zinc respectively. . At present, most of the traditional heating furnaces for non-ferrous metals in our country use iron crucible external heating methods, which have problems such as severe crucible corrosion, high energy consumption, serious environmental pollution, and low resource utilization, especially due to the formation of large amounts of slag due to zinc-iron and aluminum-iron reactions , Causing problems such as large l...
