The furnace body is a cylinder structure. The furnace body wall has Nanometer heating insulation temperature preserved layer. The aluminum alloy electric temperature furnace has the advantages of high heating efficiency, heating evenly, easy maintenance, and less energy consumption loss.
Description
Technical field
The utility model relates to a kind of industrial furnace, relates in particular to a kind of aluminium alloy electric holding furnace.
Background technology
Theoretically, the object of a uniform temperature, it just can maintain on this temperature forever if do not dispel the heat.The transmission of heat has convection current, radiation and three kinds of modes of conduction, especially with conduction pattern the most effectively.The Al alloy thermal insulation stove generally just plays the stable effect of keeping aluminium liquid original temperature, owing to exist various heat radiation factors, so just need be incubated and supplementary heating to molten aluminium alloy, if it is energy-conservation that the Al alloy thermal insulation stove will be accomplished, just must solve mode of heating and two problems of heat insulation effect.Existing aluminium alloy electric holding furnace uses heating wire or Elema mostly, radiation heating above aluminium liquid.This belongs to the indirect mode, make the air themperature on aluminium liquid top to raise, make aluminium liquid produce oxidization burning loss easily, and heating weak effect, heating wire (Elema) temperature height, service life are short, simultaneously in order to guarantee the thermal effect that adds of aluminium water, heating surface must have certain area, and the liquid level of aluminium liquid can not be dark excessively, otherwise can cause non-uniform temperature up and down; But liquid level is shallow excessively, and the amount that makes aluminium water to scoop out again is limited; In addition, the aluminium water capacity in the stove can not be very little, because very little, and in order to guarantee heating surface (area) (HS, the result, the aluminium water liquid level degree of depth is too shallow, and manipulator can be run into furnace bottom.
At present, the stove of external import has the mode of use electrothermal radiation tube insertion aluminium liquid heating, but generally all is heating bottom aluminium liquid, causes the sealing difficulty of electrothermal radiation tube and aluminium liquid, easy generation to leak and the certain danger of existence; In addition, when electrothermal tube damages replacing, also aluminium water to be scooped out, time-consuming, effort, influence is produced normally.
Owing to use conventional at present insulation material, the heat radiation of existing Al alloy thermal insulation stove furnace wall is bigger, has caused the energy consumption of present domestic electric holding furnace high.
The utility model content
Goal of the invention of the present utility model provides a kind of efficiency of heating surface height, homogeneous heating, and the Al alloy thermal insulation stove of easy maintenance is to overcome the deficiency that prior art exists.
In order to realize the foregoing invention purpose, a kind of aluminium alloy electric holding furnace of the present utility model comprises it is characterized in that the bell of body of heater and installation and body of heater top: many bringing-up sections are installed on the described bell go deep into the subsurface electric heating tube of aluminium liquid in the stove.
The upper end of described heating tube has the terminal box that is installed on outside the bell, and top is the non-heating section of drawing, and the bottom is a bringing-up section, and bringing-up section is enclosed with SIALON (pure silica is made in isostatic pressing) protective sleeve.
Because this mode of heating is the conduction heating, the efficiency of heating surface is than high many of radiation heating, and heating is the heating together up and down at aluminium liquid, homogeneous heating, so aluminium liquid liquid level can do deeply, need not to consider the heating surface (area) (HS problem that the amount of scooping out of aluminium liquid has increased, it is less that the aluminium liquid capacity of whole stove can be done, and can satisfy the demand of small-sized die casting machine.Because electric heating tube is the monomer absolute construction, replacing and convenient does not influence the normal use of stove basically again.
In order to reduce the energy consumption of this Al alloy thermal insulation stove, in further improvement of the utility model, described body of heater is a cylindrical structural.Body of heater adopts cylindrical structural, is the holding furnace of square structure compared with the body of heater of same capability, and cooling surface area significantly reduces, and has reduced energy consumption.
In order more one to go on foot the attenuating energy consumption, in the further improvement of the present utility model, has the nano heat insulating material heat-insulation layer in the furnace wall of described body of heater.
Therefore, a kind of aluminium alloy electric holding furnace of the present utility model has efficiency of heating surface height, homogeneous heating, easy maintenance, the advantage that energy loss is little.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of aluminium alloy electric holding furnace of the present utility model as shown in Figure 1 comprises body of heater 11 and bell 12.
This body of heater 11 is a cylindrical structural, and such structure is the holding furnace of square structure compared with the body of heater of same capability, and cooling surface area significantly reduces, and can cut down the consumption of energy.And in the furnace wall 16 of body of heater 11 the nano heat insulating material heat-insulation layer is arranged.Like this can be so that the thickness of furnace wall 16 has reduced to 120mm from the original 300mm from original, high insulating effect, the few body of heater profile of furnace wall heat radiation reduce, area of dissipation reduces, be fit to be installed in narrow space more, the overall power of stove has reduced by 30% than conventional radiation heating electric holding furnace.Body of heater 11 tops one side has a charge door 13, and the aluminium liquid 2 that need be incubated enters in the stove from this charge door 13 and is incubated, and body of heater 11 top opposite sides have liquid outlet 14.
Many electric heating tubes 3 are installed on bell 12, and the terminal box 31 that the upper end of this electric heating tube 3 has, this terminal box 31 are positioned at outside the bell 12 and with power supply and are connected.The top of this electric heating tube 3 is the non-heating section of drawing 32, and the bottom is a bringing-up section 33, and this bringing-up section 33 is enclosed with SIALON (pure silica is made in isostatic pressing) protective sleeve 34.When work, the bringing-up section 33 of electric heating tube 3 is goed deep in the aluminium liquid 2.Like this, the mode of heating of this aluminium alloy electric holding furnace has just become the conduction heating, the efficiency of heating surface is than high many of radiation heating, and heating is the heating together up and down at aluminium liquid, so aluminium liquid liquid level can do deeply, need not to consider the heating surface (area) (HS problem that the amount of scooping out of aluminium liquid has increased, it is less that the aluminium liquid capacity of whole stove can be done, and can satisfy the demand of small-sized die casting machine.Because electric heating tube 3 is monomer absolute construction, replacing and convenient does not influence the normal use of stove basically again.Radiation heating mode unlike original needs blowing out that bell is split out replacing, compared with the stove of import electrothermal radiation tube is installed in aluminium liquid bottom, needs aluminium water is scooped out when maintenance, and is more convenient, do not influence normal production.
