Problems solved by technology

[0004] The current reported bottom immersion heating non-ferrous metal heating furnace, that is, the heating system is inserted into the furnace from the bottom of the furnace. This method is prone to liquid leakage accidents when the protective sleeve is damaged. When replacing the heating system, the entire furnace needs to be replaced. The release of molten metal is time-consuming and energy-consuming, and the operation is very inconvenient

Embodiment Construction

[0025] Such as Figure 1~3 As shown, an upper immersion heating, melting and holding furnace of the present invention includes: a furnace body 1, a furnace cover 5, a heater 6, and an electric control cabinet.

[0026] The furnace wall of the furnace body 1 includes a three-layer structure, wherein the inner layer structure 11 is an integrally cast refractory material, the middle layer structure 12 is an insulating 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: feeding area 2, discharging area 3, and heating area 4, among which:

[0027] ——The feeding zone 2 and the discharging zone 3 are completely separated by a sealing baffle, the purpose is to prevent the temperature drop of the molten metal in the discharging zone due to the mixing of the newly added material with 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, melting and holding furnace, in particular to a heating, melting and holding furnace mainly used for smelting low melting point non-ferrous metals and their alloys. Background technique [0002] Non-ferrous metal heating furnace is the core equipment for melting, heat preservation and purification of aluminum, zinc and their alloys in hot-dip galvanizing and die-casting industries. Its annual consumption of aluminum and zinc accounts for 35% and 50% of the total domestic aluminum and zinc consumption respectively . At present, most of the traditional non-ferrous metal heating furnaces in my country adopt the external heating method of iron crucible, which has problems such as severe corrosion of the crucible, high energy consumption, serious environmental pollution, and low resource utilization rate, especially due to the formation of a large amount of slag due to the reaction of zinc-iron and aluminum-iron. , causin...
