Abstract
The utility model discloses a heat-proof box for operation in an electric furnace. The heat-proof box is favorable for smooth overhauling operation. The heat-proof box for the operation in the electric furnace comprises a rear box plate, wherein a left box plate and a right box plate are connected to the two ends of the rear box plate respectively; a lower box plate is connected to the bottom of the rear box plate; the rear box plate, the left box plate, the right box plate and the lower box plate enclose an operation cavity, and are all composite plates; each composite plate comprises a steel plate shell and asbestos filled in the steel plate shell; a lifting ring is arranged above the operation cavity, and is connected with the tops of the rear box plate, the left box plate and the right box plate through reinforcing steel bars respectively; the diameters of the reinforcing steel bars are more than or equal to 25mm. The heat-proof box is lifted into the furnace through a crane, so that an overhauling worker can overhaul the interior of the furnace in the heat-proof box; the heat-proof box can have a good heat insulation effect, and has an enough operation space, so that the smoothness of the overhauling operation is ensured, and the heat-proof box is time-saving and labor-saving.
Description
Technical field
The utility model relates to a kind of solar heat protection case, relates in particular to operation solar heat protection case in a kind of electric furnace.
Background technique
Electric furnace needs maintainer to enter in it to overhaul after using one section time.Existing maintenance mode is after the cooling certain hour of electric furnace, maintainer enters operation in stove, although electric furnace is cooling certain hour, but its inside temperature is still higher, easily cause burning of maintenance worker, whole environment is unfavorable for carrying out smoothly of upkeep operation, and whole maintenance process is wasted time and energy.
model utility content
The technical problem that the utility model solves is to provide a kind of interior operation solar heat protection case of electric furnace that upkeep operation carries out smoothly that is beneficial to.
The utility model solves the technological scheme that its technical problem adopts: operation solar heat protection case in electric furnace, comprise rearing-box plate, the two ends of rearing-box plate are connected with respectively left boxboard and right boxboard, the bottom of rearing-box plate is connected with lower boxboard, rearing-box plate, left boxboard, right boxboard and lower boxboard surround operation cavity jointly, rearing-box plate, left boxboard, right boxboard and lower boxboard are all composite sheet, described composite sheet comprises steel plate shell and is filled in the asbestos of steel plate shell inside, the top of operation cavity is provided with suspension ring, suspension ring by reinforcing bar respectively with rearing-box plate, the top of left boxboard and right boxboard is connected, the diameter of reinforcing bar is more than or equal to 25mm.
Further: suspension ring are semicircle.
Further: suspension ring are more than or equal to 20mm along the axial thickness D in suspension ring hole.
The beneficial effects of the utility model are: by solar heat protection case of the present utility model is lifted up in stove by crane, maintenance worker can be in solar heat protection case overhauls in to stove, because solar heat protection case can play good effect of heat insulation, possess again enough working spaces, upkeep operation can be carried out smoothly.Time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of operation solar heat protection case in electric furnace of the present utility model;
Fig. 2 is the schematic diagram of filling asbestos in steel plate shell;
In figure, be labeled as: suspension ring 1, suspension ring hole 2, reinforcing bar 3, right boxboard 4, lower boxboard 5, left boxboard 6, rearing-box plate 7, steel plate shell 8, asbestos 10.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As depicted in figs. 1 and 2, operation solar heat protection case in electric furnace, comprise rearing-box plate 7, the two ends of rearing-box plate 7 are connected with respectively left boxboard 6 and right boxboard 4, the bottom of rearing-box plate 7 is connected with lower boxboard 5, rearing-box plate 7, left boxboard 6, right boxboard 4 and lower boxboard 5 surround operation cavity jointly, rearing-box plate 7, left boxboard 6, right boxboard 4 and lower boxboard 5 are all composite sheet, described composite sheet comprises steel plate shell 8 and is filled in the asbestos 10 of steel plate shell inside, the top of operation cavity is provided with suspension ring 1, suspension ring 1 by reinforcing bar 3 respectively with rearing-box plate 7, left boxboard 6 is connected with the top of right boxboard 4, the diameter of reinforcing bar 3 is more than or equal to 25mm.
When use, by crane, solar heat protection case is lifted up in stove, maintainer stands in solar heat protection case overhauling in stove.Solar heat protection case can play good heat-blocking action, has stronger support strength simultaneously, and upkeep operation can be carried out smoothly.Effectively guarantee maintainer's safety.Meanwhile, the diameter of above-mentioned reinforcing bar is more than or equal to 25mm, suspension ring is connected very firm with casing.
The shape of above-mentioned suspension ring is preferably semicircle.Can be made by round plate.Because solar heat protection case is to lift up in stove by crane, in order to increase the area of contact between suspension hook and suspension ring, stationarity when increase solar heat protection case uses in stove, as shown in Figure 2, suspension ring are more than or equal to 20mm along the axial thickness D in suspension ring hole 2.
