Description
Technical Field
The invention belongs to the technical field of steelmaking and continuous casting, and particularly relates to an improved movable dust removal device for a casting area of a continuous casting machine, which covers the casting area of the continuous casting machine.
Background
Continuous casting is the main means of forming the current steel materials, and the molten steel after primary or secondary smelting is transformed into the required solid shape (slab, square billet, round billet, special-shaped billet and the like) by gradually solidifying from liquid through a continuous casting machine.
In the pouring process of a continuous casting machine, high-temperature liquid molten steel falls into a tundish from a ladle and then falls into a crystallizer from the tundish for pouring, a large amount of smoke gas can be generated in the process, particularly, the instantaneous smoke amount is large in the opening stage (casting starting stage) of a ladle nozzle, and meanwhile, smoke can be generated in the high-temperature liquid molten steel in the ladle and the tundish in the pouring process. Operators at the casting position can only work in smoke and dust, and the environment of a factory building is also damaged. The biggest obstacle to dust removal in the casting area of a continuous casting machine is that dust collecting equipment interferes with the operation of the process. The pouring area is a high-temperature liquid metal continuous operation area, a crane continuously transfers and transports the steel ladle filled with high-temperature molten steel to the steel ladle rotary table, meanwhile, an empty ladle is transferred away, the steel ladle rotary table rotates and rises, the high-temperature molten steel is uninterruptedly injected into a tundish below the steel ladle rotary table, and the steel ladle vehicle moves up and down and moves transversely along the tundish according to process requirements. Therefore, the continuous casting and pouring areas at home and abroad are not designed for dust removal for more than ten years ago. However, as the health and safety of workers are more and more emphasized in China, when the casting steel grade is required to contain more elements harmful to human bodies, dust removal measures must be taken to guarantee the personal safety of the workers. The invention relates to a movable dust removal device for a casting area of a continuous casting machine (ZL 201510203217), which is provided based on the requirement, and adopts a high-low rail structure to ensure that a dust collection cover spans a casting ladle and a tundish to cover the casting area, the cover body is divided into two halves in the longitudinal direction, the ladle turntable is ensured to freely rotate in the cover body during folding, the casting ladle is wrapped in the cover body, and the sealing dust collection effect is good. When the continuous casting machine is overhauled, the two sides of the split cover body are moved away, so that the hoisting of equipment in casting can be ensured. However, the present invention also has the following disadvantages: firstly, the dust collecting cover is too long, so that the dust collecting space is too large, dust-free air in the environment is sucked, the required dust removing air quantity is very large, the original dust removing system of a workshop is difficult to utilize, and an independent dust removing facility needs to be arranged; when the cover body leaves the pouring position, most of the operation area of the pouring platform is shielded, and the normal lifting operation of the crane across the pouring of the workshop is also influenced; and secondly, the pouring area is sealed in the cover body, so that the condition in the pouring area cannot be directly observed at any time, and the use is unacceptable for a high-risk liquid metal operation area, so that the method is only applied to a continuous casting machine with a national dust removal requirement, and is not widely popularized.
In recent years, along with the popularization of the whole-process protective pouring and the middle ladle capping pouring of a continuous casting machine and the adoption of a new technology of the whole-process capping of a ladle, except for the pouring opening stage of a ladle nozzle, the smoke dust in a pouring area is greatly reduced in normal pouring. However, the national environmental protection requirements for metallurgical enterprises are more and more strict, and dust removal in pouring areas is brought into the environmental assessment and assessment project of enterprises, which means that dust removal measures must be taken no matter what steel types are poured. The invention of the movable dust removal equipment for the casting area of the continuous casting machine (ZL 201510203217) cannot meet new production requirements due to the defects. Particularly, with the rise of a new unmanned pouring technology, the robot replaces an operator to carry out ladle pouring operation, and the dust hood of the movable dust removal equipment (ZL 201510203217) in the casting area of the continuous casting machine occupies the operation space of the robot and also influences the observation visual field of various matched cameras. Therefore, the dust removal equipment of the pouring area must be improved, and how to reduce the sealing of the pouring area and ensure the dust removal effect becomes a new technical problem.
Disclosure of Invention
The invention aims to provide improved movable dust removal equipment for a casting area of a continuous casting machine, which solves the problem that the sealing of the casting area is reduced and the dust removal effect is ensured.

The apron board and the gathering flue are welded below the low-rail side cover body and extend downwards to be close to a dust source, the flue is directly communicated with a dust removal pipeline, the smoke gathering speed is greatly improved, the flue opening is opposite to the dust source and above the dust source, a large amount of smoke can be gathered in a short distance, meanwhile, the apron board isolates airflow entering outside a pouring area, the gathering efficiency is also improved, and a small amount of smoke produced by residual overflowing smoke and the openings of the steel ladle cover and the middle ladle cover is collected through the cover body to enter the dust removal pipe. Compared with the prior art, the improved dust removing equipment improves the smoke dust collecting efficiency, changes a pouring area less and is convenient for the implementation of robot pouring. Meanwhile, the cover body is not influenced by the turning radius of the ladle turntable, the length can be reduced, the capacity of the dust removal system is reduced, and the cover body can be incorporated into the existing dust removal system.
