Description
Technical Field
The utility model relates to a steel smelting technical field especially relates to a portable ladle cover.
Background
Molten steel from a steel making furnace is poured into a ladle, is transported to a ladle turret of a continuous casting machine after secondary refining treatment, and is poured into a forced water-cooled crystallizer through a tundish. After the ladle filled with molten steel is conveyed to a revolving platform of a continuous casting machine, a ladle cover needs to be added for heat preservation, so that the temperature drop of the molten steel in the ladle is reduced.
In metallurgical production enterprises, the whole ladle capping is an ideal process production flow, and the heat loss can be reduced to the maximum extent. However, due to the layout of the factory buildings of each production enterprise, the layout conditions of the converter (electric furnace), the refining furnace and the continuous casting machine are different, and the whole-process automatic capping cannot be adopted when the hard sleeve is carried.
At present, a steel ladle rotary table is generally provided with a rotatable fixed type ladle cover, and the steel ladle can be covered and insulated by one-key operation after the steel ladle is in place. The steel ladle capping and heat preservation is a main operation procedure for reducing heat loss and improving the casting stability of molten steel, and a fixed steel ladle cap often cannot be normally used due to pressure relief of a steel ladle cap lifting oil cylinder body, oil pipe breakage, a limit signal and other reasons, so that the molten steel cannot be preserved heat, the temperature of the molten steel is rapidly reduced, and great difficulty is brought to production operation. At this time, a measure is urgently needed to compensate for the passive situation of production during the failure of the fixed ladle cover.
In the patent CN202022507103.0, the lifting ring is complex and complicated in arrangement, the lifting ring is not beneficial to hanging of a crown block hook, and the key link of reducing the smelting period and improving the production stability is to reduce the extra auxiliary time as much as possible due to the tight rhythm of the steelmaking production. In the patent CN201420330178.9, there is no reinforcing device for the ladle cover end enclosure, there is no sealing and anti-dropping device for the refractory fiber block filled inside the end enclosure, and as time goes on, the refractory fiber block gradually drops off due to the interaction force between the steel ladle cover pressure and the steel slag at the ladle opening, and then the ladle cover end enclosure is baked at high temperature in the ladle, which results in the damage and deformation of the ladle cover end enclosure, and the refractory fiber block drops into the ladle to cause molten steel pollution.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a portable steel ladle cover, including the be built by contract body, the be built by contract body is the open hollow cylinder structure in top surface closure, bottom surface, and the center of top surface is equipped with the lewis hole, and this intussuseption of be built by contract is filled with high temperature resistant heat preservation cotton.
The utility model discloses the technical scheme who further injects is:
according to the movable ladle cover, the high-temperature-resistant sealing net is arranged below the high-temperature-resistant heat-insulation cotton.
The movable steel ladle cover is characterized in that a circle of covered edge is arranged at the edge of an opening of the bottom surface, and a high-temperature-resistant sealing net is fixed on the covered edge.
The width of the edge of the movable ladle cover is 100mm.
The movable ladle cover is characterized in that the top surface of the movable ladle cover is provided with a plurality of reinforcing ribs which are uniformly distributed.
The movable ladle cover has the advantages that one end of the reinforcing rib is connected with the lifting hole, and the other end of the reinforcing rib is connected with the edge of the ladle cover body.
The bottom surface of the ladle cover body is made of high-temperature-resistant metal plates with the diameter of 3800-4000mm, the height of the ladle cover body is 150-200mm, the thicknesses of the lifting holes and the bottom surface of the ladle cover body are 30mm, and the thicknesses of other parts of the ladle cover body and the covered edges are 10-20mm.
The beneficial effects of the utility model are that: the problem that the molten steel cannot be insulated during the fault period of the fixed steel ladle cover is solved, great stability is brought to smooth production, and the consumption of steel materials and the labor intensity of workers are reduced.

Detailed Description
The structure of the movable steel ladle cover provided by the embodiment is shown in fig. 1-2, and comprises a ladle cover body 3, wherein the ladle cover body 3 is a hollow cylindrical structure with a closed top surface and an open bottom surface, a hanging hole 1 is formed in the center of the top surface, high-temperature-resistant heat-insulating cotton 6 is filled in the ladle cover body 3, a high-temperature-resistant sealing net 5 is arranged below the high-temperature-resistant heat-insulating cotton 6, a circle of edge cover 4 is arranged at the open edge of the bottom surface, the width of the edge cover 4 is 100mm, and the high-temperature-resistant sealing net 5 is fixed on the edge cover 4. The top surface is provided with a plurality of reinforcing ribs 2 which are evenly distributed. One end of the reinforcing rib 2 is connected with the lifting hole 1, and the other end is connected with the edge of the ladle cover body 3.
The bottom surface of the ladle cover body 3 is made of a high-temperature resistant metal plate with the diameter of 3800-4000mm, the height is 150-200mm, the thickness of the hanging hole 1 and the bottom surface of the ladle cover body 3 is 30mm, and the thickness of other parts of the ladle cover body 3 and the thickness of the edge cover 4 are 10-20mm.
