Abstract
The utility model relates to a furnace cover of a vacuum furnace in the metallurgical industry and particularly relates to a water-cooled furnace cover of the vacuum furnace. The water-cooled furnace cover comprises water-cooled coils arranged on the furnace cover, joints of all the water-cooled coils are positioned on one side of the furnace cover, and the water-cooled furnace cover is characterized in that the included angle between each of the center-to-center connection lines of all the water-cooled coils and the vertical center line of the water-cooled furnace cover is 75 degrees. According to the water-cooled furnace cover disclosed by the utility model, a two-piece type water cooling plate of the original water-cooled cover is changed to an integrally welded type, decomposition after cracking of weld joints can be avoided, the inclination angle of the water-cooled cover is adjusted, and the furnace cover can be increased as far as possible under the situation of not affecting the empty visual angle of an observation hole of a tank cover; and simultaneously, a water cooling circulating path of the water-cooled cover is optimized, the cooling effect of the water-cooled cover is improved, steel slag formed on the furnace cover is reduced, the service life of a hoisting chain of the water-cooled cover is prolonged, and the like. The water-cooled furnace cover disclosed by the utility model can reduce the workload of a worker in clearing the furnace cover, improve the safety performance in use of the furnace cover, prevent the furnace cover from being adhered to a steel ladle, and avoid great running resistance and other problems.
Description
Technical field
The utility model relates to a kind of metallurgy industry vacuum drying oven bell, specifically a kind of vacuum drying oven water cooled cover.
Background technology
In vacuum drying oven vacuum processing of liquid steel process, because unstable gas is large in the molten steel, molten steel is in often boiling splash in vacuum treated early stage, a large amount of bonding slags on original bell, in the process that furnace cover lifting moves, slag and ladle that water-cooled covers are bonded together, and the trolley travelling resistance is large, easily bell are damaged; After application of vacuum finished in addition, the workman will clear up the slag that water-cooled covers, because temperature is high, it is large to deal with labour intensity.
The utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of vacuum drying oven water cooled cover is provided, avoid bell to amass slag, alleviate the workload that the workman clears up bell, improve the security performance that bell uses, avoid bell and ladle bonding, the problem such as running resistance is large.
The technical scheme that the utility model solves above technical problem is:
A kind of vacuum drying oven water cooled cover,, comprise the water-cooled coil pipe that is arranged on the bell, it is characterized in that: the joint of described each water-cooled coil pipe all is positioned at a side of bell, and the angle between the line of each aqueous cold plate tube hub and the water cooled cover vertical center line is 75 degree.
The technical scheme that the utility model further limits is:
Aforesaid vacuum drying oven water cooled cover, water-cooled coil pipe are the integral solder pipe.
Aforesaid vacuum drying oven water cooled cover, the return pipe that advances of water cooling tube coil pipe is alternately arranged, and guarantees that cooling effect is best.
The beneficial effects of the utility model are: the utility model is used two formula cooled plate of original water-cooled lid instead whole welding type, avoid decomposing behind the weld cracking, adjust the angle that the water-cooled lid tilts, in the situation that does not affect the empty visual angle of cover peep hole, increase bell as far as possible; Meanwhile, optimize the path of water-cooled lid water cooling circulation, improve the cooling effect of water-cooled lid, reduce bell knot slag, improved the service life of water-cooled lid lifting chain etc.The problems such as the utility model can alleviate the workload that the workman clears up bell, improves the security performance that bell uses, and avoids bell and ladle bonding, and running resistance is large.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Embodiment 1
Present embodiment provides a kind of vacuum drying oven water cooled cover, structure as shown in Figure 1, comprise the water-cooled coil pipe 1 that is arranged on the bell, the joint of each water-cooled coil pipe 1 all is positioned at a side of bell, and the angle between the line at each water-cooled coil pipe 1 center and water cooled cover 2 vertical center lines is 75 degree.The water-cooled coil pipe is the integral solder pipe, uses two formula cooled plate of original water-cooled lid instead whole welding type, avoids decomposing behind the weld cracking, adjusts the angle that the water-cooled lid tilts, and in the situation that does not affect the empty visual angle of cover peep hole, increases bell as far as possible.Optimize the path of water-cooled lid water cooling circulation, the return pipe that advances of water cooling tube coil pipe is alternately arranged, and guarantees that cooling effect is best, improves the cooling effect of water-cooled lid, reduces bell knot slag, has improved the service life of water-cooled lid lifting chain etc.The problems such as the utility model alleviates the workload that the workman clears up bell, improves the security performance that bell uses, and avoids bell and ladle bonding, and running resistance is large.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (3)
