Abstract
The utility model relates to a heat insulating furnace structure for molten aluminium, which particularly comprises an outer shell, upper covers, a heat insulating groove, a sand layer and castable refractory materials. The heat insulating groove is inside provided with a partition board, and a feed groove, a temperature measuring groove, a material taking groove, and a heat insulating and still positioning groove are formed. The inner side circumference edge and the bottom of the outer shell are coated with castable refractory materials, the castable refractory materials are provided with the sand layer, the heat insulating groove is arranged in the sand layer, space is filled with heat insulating sands, and small comb-shaped circular holes are formed between the heat insulating and still positioning groove and the feed groove. The sand layer is provided with a refractory plate, and a plurality of upper covers are covered to be convenient for the permutation of the heat insulating groove after refractory fiber cotton is arranged on the refractory plate.
Description
A kind of aluminium water holding furnace belongs to the metal manufacture field.
The aluminium water holding furnace of prior art, when the insulation groove is heated, not have the buffering flow velocity very fast because of aluminium water behind insulation groove (being inner bag) high temperature aluminum water (generally more than the 657 ℃) pan feeding bottom, upper strata aluminium ripples move and are combined into aluminium oxide with air, aluminium oxide (aluminium slag) is useless and discarded, aluminium oxide increases makes cost increase and increase the weight of environmental protection treatment, moreover insulation groove inwall is made with modes such as heat-resisting dividing plate precastings, between outside iron-clad and heat-resisting dividing plate, be coated with one deck castability heat proof material, treat the fixed back of castability heat proof material and heat-resisting dividing plate the insulation groove, after this insulation groove uses a period of time, can the aging cracking distortion scrap because of expanding with heat and contract with cold for a long time, prior art is that insulation groove and castability heat proof material are smashed double teeming, and this is uneconomical in time, and is also pretty troublesome in the manufacturing.
The purpose of this utility model provides a kind of improvement structure of aluminium water holding furnace, makes the aluminium water in the stove keep constant temperature, unlikely heat or insulating process in, because of upper strata aluminium water level fluctuation forms aluminium oxide, can make the insulation groove make and maintenance on save the plenty of time.
The purpose of this utility model can realize by following measure, promptly periphery and bottom scribble castable refractories inside the shell, be covered with a layer of sand on castable refractories surface, bottom, the insulation groove is located at wherein, the insulation groove outside and be filled with heat insulating sand between the castable refractories, leave standstill in insulation and be set as several honeycomb small sircle holes between groove and the feed chute, be provided with refractory plate on the layer of sand surface, refractory plate is provided with refractory fiber cotton, and refractory fiber cotton is provided with several loam cakes.
The utility model has the advantages that: make the aluminium water in the holding furnace keep constant temperature, insulation groove upper strata aluminium water is unlikely to fluctuate and the generation aluminium oxide in adding gentle insulating process, cause waste, avoid also being incubated that groove is aging, be full of cracks, distortion and scrap, increase the service life, change the insulation groove easy, save time.
The explanation of accompanying drawing drawing:
Fig. 1 is a schematic appearance of the present utility model
Fig. 2 is an insulation groove schematic internal view of the present utility model
Fig. 3 is a phantom of the present utility model
Now contrasting accompanying drawing is described in detail as follows the utility model:
The improvement of aluminium water holding furnace structure of the present utility model comprises a shell 1, several loam cakes 2, an insulation groove 4, layer of sand 5, a castable refractories 6; Its shell 1 is to make with metal, insulation groove 4 uses template die to make in modes such as precastings, dividing plate 7 is one-body molded with insulation groove 4, be provided with several dividing plates 7 in the insulation groove 4, and forming that a feed chute 8, a thermometric groove 9, are got hopper 10 and groove 11 is left standstill in an insulation, insulation is left standstill groove 11, thermometric groove 9 and is got and all is provided with perforation 12 between the hopper 10; Thermometric groove 9 and getting is provided with a perforation 12 between the hopper 10, be characterized in: insulation is left standstill and is provided with several honeycomb small sircle holes 13 between groove 11 and the feed chute 10, after high temperature aluminum water is poured into from feed chute 8, aluminium water can reduce pressure through several honeycomb small sircle hole 13 its flow velocitys and slowly flow into insulation and leave standstill groove 11, and flow to thermometric groove 9 simultaneously and get hopper 10, this moment, aluminium water liquid level rose gradually, at pan feeding or get the neither meeting of when material aluminium layer waterborne and cause fluctuation, thereby be difficult for producing aluminium oxide, go a step further the identical position of being located at thermometric groove 9 of temperature-sensitive groove with prior art than existing aluminium water holding furnace; Its production process is: the inboard periphery and the bottom that earlier castable refractories 6 evenly are applied to shell 1, treat that fixed back is in the shop, surface of the castable refractories 6 of bottom one deck sand 5, the material of this layer of sand 5 is a refractory heat-insulating sand, to be incubated groove 4 is placed on middle, heat insulating sand is inserted between insulation groove 4 outsides and the castable refractories 6 in the space, refractory plate 14 is placed the layer of sand surface, be provided with refractory fiber cotton 15, cover with number loam cake 2 at last on refractory plate 14 upper stratas; In the loam cake of groove 11 upper ends is left standstill in insulation, be provided with electrothermal tube and heat, make the aluminium water that insulation is left standstill in the groove 11 can keep constant temperature with radiation mode; After holding furnace 3 uses a period of time, in the time of must changing insulation groove 4, need only the layer of sand 5 usefulness dust catchers suction of refractory plate 14 lower ends is clean, can easily take out insulation groove 4, aforesaid way is reentered into new insulation groove 4 for another example, and is very convenient, saves time and saves trouble.
The utility model improves greatly to prior art, and pan feeding can not produce aluminium oxide when getting material, and after use a period of time, it is also very convenient to change the insulation groove, saves the trouble that aluminium water has reduced environmental protection treatment.
