A device for automatically adding and uncovering an iron clad and its implementation method

Abstract

The invention relates to an iron ladle automatic cover removal device, comprising an iron ladle, a ladle cover installed on the top of the iron ladle, a plurality of gantry lifting lugs fixed on the ladle cover, a translational trolley rail, a lifting guide rail, a translational trolley, and an automatic control device , the driving device and safety emergency device installed at the rear of the translation trolley. The present invention can realize hoisting with a cover and ironing with a cover, instead of fixing the cover on the transport vehicle, and realizes the true meaning of one package of molten iron to the bottom, and the whole process of covering and heat preservation of the iron ladle, which can not only ensure the sealing effect of the cover, but also shorten the waiting time. The lid is kept warm, and the lid is opened before tapping, so as to maximize the extension of the heat preservation time ratio of the iron ladle, and at the same time lay the foundation for making full use of the heat of molten iron to produce steel.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to an iron ladle automatic capping device and an implementation method thereof. Background technique [0002] A few days ago, during the iron ladle transportation process, the molten iron ladle was either not covered for heat preservation, or it was only designed with a cover for heat preservation on the transport vehicle. It did not realize the hoisting of the iron ladle with a cover and the mixing of iron with a cover. It is difficult to complete the whole process from tapping to iron mixing. Covered for heat preservation, the temperature drop of molten iron is not the smallest. However, the production process of automobile transportation of molten iron is one bag to the end, and the space for the tap position is compact.

Problems solved by technology

[0002] A few days ago, during the iron ladle transportation process, the molten iron ladle was either not covered for heat preservation, or it was only designed with a cover for heat preservation on the transport vehicle. It did not realize the hoisting of the iron ladle with a cover, and the mixing of iron with a cover. It is difficult to complete the whole process from tapping to iron mixing. Covered for heat preservation, the temperature drop of molten iron is not the smallest

However, the production process of automobile transportation of molten iron is one bag to the end, and the space for the tap position is compact. The iron ladle needs to be turned over in different directions, so that it has a high and low structure design of the size of the bag mouth. The ordinary structure of the cover cannot realize the iron turned over with a cover. , so that it is more difficult to realize the whole process from tapping to ironing, and returning the empty bag to tapping with a cover and heat preservation. The main reasons are:

[0003] 1. In the production process of automobile transportation of molten iron in one bag to the bottom, due to the compact space of the iron mixing position, it is difficult to lift the iron ladle cover at the tapping position to cover and uncover;

[0004] 2. In the past, iron ladle capping was generally done by installing the ladle cover on the transport vehicle. It is even more difficult to realize automatic capping and uncapping of the iron ladle with the high and low structure design of the large and small nozzles, even if it can be driven by the molten iron transport vehicle. The realization also requires a large height space, and the combination of multiple driving devices can complete the uncovering;

[0005] 3. The iron ladle must meet the needs of transportation and hoisting with a cover, and iron with a cover. The previous structure and design cannot realize the whole process of covering and heat preservation
