Abstract
The utility model relates to a detachable heat-preserving furnace door. The detachable heat-preserving furnace door is characterized in that a steel frame which has the same size with the heat-preserving furnace door is designed, and the steel frame is connected with a heat-preserving furnace door body through a fixing bolt and composed of an inner layer and an outer layer. A furnace door handle is installed on the outer frame and the inner frame is provided with a first fire-resistant material. A second fire-resistant material is arranged in the outer frame. Compared with an integrated cast furnace door, the heat-preserving furnace can be detached, so that maintenance is more convenient. Meanwhile, as the steel frame with the inner layer and the outer layer is adopted, the furnace door has larger bearing force for impact caused by frequent opening and closing of the heat-preserving furnace door. As the design of the double-layer fire-resistant materials is adopted, the better heat-preserving effect is achieved.
Description
Technical field
The utility model relates to smelting equipment field, relates in particular to a kind of detachable holding furnace fire door.
Background technology
Aluminium alloy smelting is first link that aluminium alloy car is produced, and alloy pig melts and finally through holding furnace, goes out aluminum casting after feeding intake, and therefore the switch of holding furnace fire door is very frequent.Existing aluminum alloy smelting furnace holding furnace aluminium flowing-out mouth fire door is that monoblock type refractory material casting forms, though this structure is conducive to the insulation of smelting furnace, switch frequently causes very large shock to fire door at every turn, and the service life of fire door is very short; Because being that integrated pouring forms, fire door often keeps in repair very inconvenient after damaging, and therefore aluminum wheel of vehicle industry need to be innovated a kind of holding furnace fire door firmer, more easy-maintaining.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of easy-maintaining, Al alloy thermal insulation furnace door are more firmly provided, and specifically refers to a kind of detachable holding furnace fire door.
The concrete scheme of realizing above technology is: a kind of detachable holding furnace fire door, it is characterized in that, design a kind of steel framework consistent with holding furnace fire door size, steel framework links by set bolt and holding furnace body of heater, and steel framework forms by inside and outside two layers, wherein on housing, handle of fire gate is housed, in inside casing, be provided with refractory material one, in housing, be provided with refractory material two, compared with integrated casting type fire door, because this holding furnace is detachable, therefore more convenient when maintenance; Owing to adopting inside and outside two layers of steel framework, the impact that needs frequent switch to cause to holding furnace fire door has larger holding capacity simultaneously; The design of employing double-layer refractory material, has better heat insulation effect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, a kind of detachable holding furnace fire door, comprises inside casing (1) and housing (2), has set bolt one (3) on inside casing (1), and set bolt one (3) can firmly be connected thermal insulation furnace body with inside casing (1); There is refractory material one (5) inside casing (1) inner side; On housing (2), have set bolt two (4), between inside casing (1) and housing (2), have refractory material two (6), housing (2) is provided with handle of fire gate (7), and this holding furnace fire door has high insulating effect, firmer, easily detachable feature.
Claims (1)
1. a detachable holding furnace fire door, is characterized in that: comprise inside casing (1) and housing (2), have set bolt one (3) on inside casing (1), set bolt one (3) can firmly be connected thermal insulation furnace body with inside casing (1); There is refractory material one (5) inside casing (1) inner side; On housing (2), have set bolt two (4), between inside casing (1) and housing (2), have refractory material two (6), housing (2) is provided with handle of fire gate (7).
