Abstract
The invention relates to a steel ladle cover device with an opening structure and belongs to the technical field of steel ladle cover devices. The steel ladle cover device with the opening structure is applied to a refractory material used for protecting a steel ladle cover when deslagging is conducted on a steel ladle with a cover. According to the technical scheme, the steel ladle cover device with the opening structure comprises a steel-structural frame, lifting lugs, a hook, a ladle cover shell and a refractory material, wherein the steel-structure frame and a steel ladle shell are welded together, the steel ladle shell is filled with the refractory material, the opening structure is designed to be located at the position opposite to the hook, the steel ladle cover is hinged to the steel ladle through the hook, and the steel ladle cover and the steel ladle coincide together in the normal operating state; when deslagging is conducted, an angle which ranges from 0 degree to 60 degrees is formed between the steel ladle cover and the edge of the steel ladle; when liquid steel slag flows out, scouring of the steel slag to the steel ladle cover can be greatly reduced due to the fact that the steel ladle cover is provided with the opening structure, and the service life of the steel ladle cover is greatly prolonged.
Description
Art
The present invention relates to a kind of steel ladle cover having hatch frame, use in iron company's steel ladle full stroke covering system.
Background technology
Along with the application of steel ladle full stroke covering technology, ladle deslagging with cover must can realize the full stroke covering of ladle.In the process of steel ladle full stroke covering, during ladle deslagging with cover, the liquid steel slag of high temperature when flowing out ladle, because original steel ladle cover structure is consistent with ladle mouth shape, all as a whole circular configuration, therefore in the firm incipient stage of deslagging, slag very easily washes away clad shell and the refractory material of steel ladle cover, and cause steel ladle cover to be out of shape, refractory material comes off, the life-span of steel ladle cover is short, and part slag can not pour slag ladle into smoothly.For avoiding or alleviating this type of loss, can only first steel ladle cover be thrown off when ladle deslagging or increase dump angle, if steel ladle cover is thrown off rear steel ladle cover can lose heat greatly, add the unnecessary activity duration, and if increase the unstability that dump angle can will increase ladle simultaneously.
Summary of the invention
The object of this invention is to provide a kind of steel ladle cover having hatch frame, for steel ladle full stroke covering system, enable ladle with cover protect clad shell and the refractory material of steel ladle cover when deslagging, and deslagging smoothly, solve the problems referred to above that background technology exists.
Technical solution of the present invention is: the steel ladle cover composition of hatch frame comprises steel frame, hanger, hook, clad housing, refractory material.Steel frame and ladle shell weld together, and fill in ladle shell with refractory material, and the design attitude of hatch frame is at the reverse position of hook, and steel ladle cover is hinged by hook and ladle, and in the normal stage run, steel ladle cover and steel ladle edge coincide together; When carrying out deslagging operation, steel ladle cover and steel ladle edge produce the angle of 0-60 °, and when liquid steel slag flows out, because ladle is stamped hatch frame, slag will obviously reduce washing away of steel ladle cover, and the service life of steel ladle cover is greatly improved.
Accompanying drawing explanation
The invention will be further described by reference to the accompanying drawings:
Fig. 1 is steel ladle cover front view of the present invention
Fig. 2 is steel ladle cover top view of the present invention
Fig. 3 is the relative position schematic diagram of steel ladle cover of the present invention and door assembly with hinge and glass in right hand and left ladle
Fig. 4, Fig. 5 are the schematic diagram of steel ladle cover of the present invention when ladle deslagging with cover
Wherein: 1. link up with, 2. hanger, 3. steel frame, 4. clad housing, 5. refractory material, 6. hatch frame, 7. ladle, 8. hinge seat, 9. husky mouth (peep hole) is filled with
Detailed description of the invention
Steel ladle cover is connected by the hinged and ladle-7 between hanger-2 and hinge seat-8, and when running well, steel ladle cover lies on ladle-7, and the angle between steel ladle cover and ladle-7 is 0 degree, and steel ladle cover and ladle-7 are run between each station by crane for hoisting.When ladle-7 with cover carries out deslagging operation, ladle-7 and steel ladle cover rotate centered by ladle trunnion; When ladle 90-degree rotation, steel ladle cover is with the bearing pin on hinge seat-8 for pivot starts to rotate, and constantly increase by 0 degree with the angle of ladle-7, liquid steel slag starts to flow out outward from ladle bottom.Because the refractory material at hatch frame-6 place and clad housing are all cancelled, the situation of originally washing away steel ladle cover and refractory material obviously alleviates, and the life-span of steel ladle cover have also been obtained great raising.
Above the steel ladle cover with hatch frame used in a kind of iron company provided by the present invention steel ladle full stroke covering system is described in detail, apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
