Abstract
The utility model relates to an infrared heating furnace for an aluminium section mould, which comprises a furnace body made of heat-resistant materials, a hearth which is arranged in the furnace body for placing a heated mould, an electrical heating element which is arranged in the hearth, wherein, the electrical heating element adopts a plurality of carborundum infrared heating tubes which are connected in series, a metal bracket is arranged on the wall of the hearth, each of the carborundum infrared heating tubes is hung on the metal bracket in parallel. The design which adopts thermal radiation for heating has the advantages of high thermal efficiency, fast heating speed, convenient mounting and maintenance, long service life, etc. The utility model can be widely used in the industry of aluminium section manufacturing.
Description
Technical field
The utility model relates to the heating furnace of aluminium section die, particularly the improvement of heating furnace mode of heating, heating.
Background technology
At present, no matter traditional aluminium section die heating furnace is horizontal or vertical, its burner hearth is general to adopt powerful electric furnace heating wire, and makes bearing support with refractory brick, by cross-ventilated mode the aluminium section die in the burner hearth is heated, for making heating-up temperature reach about 500 ℃ every 0.1m
3The space often needs tens kilowatts electric thermal power.Because adopt cross-ventilated mode of heating, the heating temperature rise of aluminium section die is slower, easily oxidation of surface, and also the heat transmission has intermediate medium, and thermal losses is bigger, and the thermal efficiency is relatively poor, thereby consumes a large amount of electric energy.Therefore, be necessary traditional heating furnace is carried out the improvement of structure and heating element heater.
The utility model content
The purpose of this utility model is the weak point that overcomes above-mentioned conventional art, proposes that a kind of firing rate is fast, the thermal efficiency is high, the infrared furnace that is used for aluminium section die of easy to install, long service life.
The purpose of this utility model is achieved by the following technical solution: the infrared furnace that is used for aluminium section die, include in the body of heater made by heat proof material, the body of heater and be used to place the burner hearth that is heated mould, be loaded on the heating in the burner hearth, heating adopts the many carborundum infrared heating tubes that are connected in series, hearth wall is provided with metallic support, and the exothermal infrared tube side-by-side button of each carborundum is hung on the metallic support.Further, install, change for convenient, have the hanging groove with certain inclination angle on the metallic support, carborundum infrared heating tube two ends button is hung on the hanging groove.For prolonging the service life of heating wire, the diameter of the heating wire in the carborundum infrared heating tube is 1.5-3.0mm.For making heat conduction fast and high temperature resistant, body of heater is a multi-layer compound structure, is metal shell, aluminium silicate wool heat-insulating material, corrosion resistant plate, aluminum silicate fiber paper, infra-red paint from outside to inside successively.
Such structure has tangible advantage:
1, adopt infrared heating tube as heating element heater, changing traditional Convective Heating is the heat radiation heating, and thermal losses is little, thermal efficiency height;
2, infrared radiation heating of metal mould, the heat conduction is from inside to outside, mold heated speed is fast, and the surface is difficult for oxidized;
3, the carborundum infrared heating tube is high temperature resistant, is applicable to the working environment about 500 ℃, long service life;
4, it is simple and convenient that heat-generating pipe is installed replacing, is convenient to the regular maintenance of heating furnace.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that schematic diagram is looked on the left side of Fig. 1;
Fig. 3 is the section enlarged diagram of body of heater;
Fig. 4 is the serial connection schematic diagram of heat-generating pipe.
The specific embodiment
Referring to Fig. 1-Fig. 4, the aluminium section die heating furnace of present embodiment includes body of heater 1, burner hearth 2, aluminium section die is transported mould trolley 3, control electronic box 4, the blower fan 5 of turnover burner hearth 2.The inwall of burner hearth 2 adopts carborundum infrared heating tube 6 as heating, for cooperating infrared heating tube 6, body of heater 1 adopts compound heat insulation structural, by outward inward, outermost layer is a metal shell 11, is aluminium silicate wool thermal insulation layer 12 then, then is corrosion resistant plate 13, post aluminum silicate fiber paper 14 on the corrosion resistant plate 13, on lead silicate fiber paper 14, be coated with infra-red paint layer 15 (as shown in Figure 3) again.For infrared heating tube 6 is installed, burner hearth 2 inwalls are provided with metallic support 7, have at interval on the metallic support 7 with the hanging groove 71 at inclination angle obliquely, and infrared heating tube 6 two ends button is hung on the hanging groove 71, infrared heating tube 6 connects the 220V dispatch from foreign news agency, and it is one group that per four infrared heating tubes 6 are connected in series, and forms the mode of operation of big current low voltage.For making the high-power heating of carborundum infrared heating tube 6, guarantee that the temperature in the burner hearth 2 reaches about 500 ℃, the diameter of heating wire is 1.5-3.0mm in the infrared heating tube 6.Such structure, than traditional electric furnace heating wire reheating furnace energy-saving 30-50%, firing rate improves 1 times, and no matter horizontal or vertical mold heated stove all applicable.
Certainly, only enumerate a kind of preferred implementation here, the technical program can be done other and be equal to or variation roughly the same, repeat no more here, but they should belong to the protection domain of this patent.
Claims (4)
