Abstract
The utility model relates to a nonferrous metal pond type thermal insulation furnace. A furnace body is composed of an inner layer and an outer layer, wherein, the outer furnace body is composed of an upper furnace body and a lower furnace body which are made from heat-insulating material; the inner furnace body forms a pond shape by high-temperature resistant material with compact texture, and the external shape of the inner furnace body is coincident with the inner shape of the lower furnace body. A heating element is directly arranged on the upper part of the interior of a furnace chamber, and the thermal insulation of molten metal is realized by the direct radiation of the heating element and the heat conduction among the molten metal. The utility model has the advantages that the utility model can avoid the loss of a crucible, can not lower the quality of the molten metal and has the advantages of long service life, high heat-transfer efficiency and good energy saving effect. The utility model is an ideal thermal insulation furnace for nonferrous metal.
Description
The utility model relates to a kind of non-ferrous metal holding furnace, particularly a kind of pond formula holding furnace that does not have the cast iron crucible.
In the non-ferrous metals casting process, must utilize heating and heat-insulating device fusing non-ferrous metal and molten non-ferrous metal is incubated, existing non-ferrous metal solution attemperator is that the cast iron crucible that is used to hold molten metal is housed in refractory oven, and is provided with heating element heater between furnace wall and crucible.There is following shortcoming in this holding furnace: 1, the normal phase of cast iron crucible is in the hot environment, easily because of damaged by thermal oxide, promptly need change crucible in general every month in the use, and cost is higher.2, the irony in the crucible can penetrate in the non-ferrous metal liquid, seriously reduces the quality of molten metal.3, indirectly to the molten non-ferrous metal heating, it is slow to conduct heat outside crucible for heating element heater, and the thermal efficiency is low.
Problems such as the purpose of this utility model provides a kind of non-ferrous metal pond formula holding furnace, and it is low to solve the existing non-ferrous metal holding furnace thermal efficiency, and service life is short.
The technical scheme that the utility model adopted is: the body of heater of this pond formula holding furnace two-layerly is made of inside and outside, wherein external furnace body is made up of upper furnace body and lower furnace body, upper and lower body of heater is all made with insulation material, the internal layer body of heater constitutes a pond shape by the exotic material of quality densification, and its profile is consistent with the interior shape of lower furnace body.Get molten metal for ease of dress, reduce pond prodelta clay liquid as far as possible, can at the bottom of the pond of internal layer body of heater, be provided with recess.Heating element heater directly is installed on the top in the furnace chamber, makes molten metal thermal insulation by the heat conduction between direct radiation of heating element heater and metal liquid.
Advantage of the present utility model is crucible is not set in its body of heater, directly constitutes its internal layer with refractory material, does not have the loss problem of crucible, thereby can not reduce the quality of molten metal, and helps increasing the service life.Heating element heater is directly to the molten metal heating, thus quick heating, heat transfer efficiency height, good energy-conserving effect.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1: structural representation of the present utility model.
The A-A cutaway view of Fig. 2: Fig. 1.
Embodiment: the described non-ferrous metal of present embodiment pond formula holding furnace is made up of upper furnace body 1, lower furnace body 4 and internal layer body of heater 5, as shown in Figure 1, 2, wherein internal layer body of heater 5 is to make with steel fiber reinforced concrete, it is embedded in the lower furnace body 4, on at the bottom of the pond of this internal layer body of heater 5, be provided with a recess with preceding fire door 3 corresponding positions, when hydrops is less in the pond, can collects in this automatically and sentence and be convenient to take and remove remaining molten metal.Also be provided with a skimming gate 6 in the upper end of internal layer body of heater 5, the corresponding site that it passes lower furnace body leads to outside this holding furnace, is used for removing the impurity of molten metal in the stove.Be provided with a back bell 7 at these skimming gate 6 places, when not skimming operation, it can be covered to reduce thermal losses.The described upper furnace body 1 of present embodiment is made by no asbestos calcium silicate board with microporous, which is provided with insulated wall 2 and preceding fire door 3, and the effect of insulated wall is the thermal cycle that improves in the furnace chamber, and preceding fire door 3 is used for dress and gets molten non-ferrous metal.This routine described heating element heater is several Elemas 8, its outside is with sleeve pipe 10, above-mentioned heating element heater is the top in furnace chamber horizontally, one side of insulated wall 2, for helping the heat transmission, improve thermal cycle in the furnace chamber, each the heating element heater along continuous straight runs in this example is arranged in upper and lower two rows, wherein one group of lower close insulated wall 2 of position is installed, and one group of higher close skimming gate 6 of position is installed.In addition, outside body of heater, establish a protective cover 9, to guarantee the heating element heater safe handling with the corresponding position of heating element heater.
