Abstract
The utility model discloses a rapid washing device for a long water nozzle of a large ladle. The rapid washing device for the long water nozzle of the large ladle comprises a washing guide pipe, wherein one end of the washing guide pipe is connected with an externally-connected oxygen pipe through a rapid locking knob, a washing head which is used for carrying out washing on the long water nozzle of the large ladle is arranged at the other end of the washing guide pipe, a spraying surface of the washing head is of a circular-arc-shaped vertical face structure, a plurality of spraying holes are formed in the circular-arc-shaped vertical face, a certain angle is formed between the axis of each spraying hole in the spraying surface and the spraying surface, the fact that airflow sprayed out of the spraying holes carries out rotation is ensured, and a cover plate which is used for preventing the airflow and residual steel from splashing upwards in the process of washing is arranged between the washing head and the washing guide pipe. The rapid washing device for the long water nozzle of the large ladle greatly improves washing quality of the long water nozzle, reduces the time for washing, provides conditions for continuous casting, avoids shut-down loss because of inappropriate washing or due to the fact that time for washing is not enough, stabilizes steel currents, reduces product quality exceptions caused by shut-down, and improves product quality.
Description
Technical field
The utility model relates to the metallurgical continuous casting field, especially relates to a kind of Quick cleaning device for continuous casting field large bag long nozzle.
Background technology
In field of steel-making, the large bag long nozzle that continuous casting is used in use needs frequent cleaning owing to reasons such as splashes, and the residual steel of inside is cleaned up, and guarantees that steel stream is smooth and easy stable.Cleaning of the prior art has dual mode usually, a kind of is breaks in production, large bag long nozzle is fully cleaned, yet this kind cleaning method is because breaks in production, can bring very large waste to production, seriously reduce production efficiency, can not guarantee the direct casting of many stoves, do not give full play to the superiority of continuous casting, affect output and affect quality yet; The second cleaning way is to be the interruption of avoiding producing, and normally utilizes the 1-2 minutes that changes bag, owing to cleaning the time pretty nervous at the mouth of a river, The faster the better therefore to require cleaning process and scavenging period; The method of wash water mouth commonly used is directly to pass into oxygen with oxygen hose to clean, however this operation be difficult to the residual steel of mouth of a river inwall is cleaned up, especially in the limited scavenging period that allows, carry out above-mentioned cleaning operation, be difficult to guarantee cleaning performance; Simultaneously, the above-mentioned operating process of having no safety devices easily causes personal injury to operating personnel.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of Quick cleaning device for large bag long nozzle for problems of the prior art, its objective is and guaranteeing under the prerequisite of breaks in production risk not, improve the cleaning efficiency of long nozzle, guarantee the cleaning quality of long nozzle, stabilized steel stream.
The technical solution of the utility model is that this kind comprises cleaning pipe for the large Quick cleaning device that wraps long nozzle, one end of cleaning pipe is connected with external oxygen hose by the quick lock in knob, the other end of cleaning pipe is provided with the cleaning head that cleans for to large bag long nozzle, the spray face of cleaning head is the circular arc facade structures, and arc-shaped surface is provided with several spray apertures.
The axis of the spray apertures on the described spray face has certain angle with respect to spray face, guarantees that the air-flow that sprays from spray apertures produces rotation.
Be provided with the cover plate that prevents that air-flow in the cleaning process and residual steel from up splashing between described cleaning head and the cleaning pipe.
This kind with said structure is used for the large Quick cleaning device that wraps long nozzle and has the following advantages:
1. this kind is used for the cleaning quality that the large Quick cleaning device that wraps long nozzle has improved long nozzle greatly; reduced simultaneously scavenging period; for condition has been created in direct casting; the shutdown loss of having avoided improper owing to cleaning or having had little time it is pressed for time to cause; Simultaneous Stabilization steel stream; reduce the product quality objection that causes thus, improved product quality.
This kind be used for large bag long nozzle Quick cleaning device owing to being provided with covering plate structure, avoided in cleaning process the security hidden trouble that operating personnel and equipment is brought because air-flow and residual steel up spill.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present utility model.
In Fig. 1,1: cleaning pipe; 2: the quick lock in knob; 3: cleaning head; 4: cover plate; 5: external oxygen hose; 6: long nozzle.
The specific embodiment
Fig. 1 is the structural representation that the utility model is used for wrapping greatly the Quick cleaning device of long nozzle, this kind cleaning device comprises cleaning pipe 1, one end of cleaning pipe 1 is connected with external oxygen hose 5 by quick lock in knob 2, the other end of cleaning pipe 1 is provided with the cleaning head 3 that cleans for to large bag long nozzle, the spray face of cleaning head 3 is the circular arc facade structures, and the circular arc facade is provided with several spray apertures, the axis of the spray apertures on the spray face has certain angle with respect to spray face, the air-flow that assurance sprays from spray apertures produces rotation, thereby plays the better spraying effect in the mouth of a river under the large bag.Be provided with cover plate 4 between cleaning head 3 and the cleaning pipe 1, the setting of cover plate 4 has been avoided in cleaning process, the security hidden trouble that operating personnel and equipment is brought because air-flow and residual steel up spill.
Utilize above-mentioned method of cleaning for the Quick cleaning device of large bag long nozzle to comprise:
1) when changing large bag, by should manipulator long nozzle 6 is shifted out middle bag, be placed on the overflow tank top;
2) described mouth of a river Quick cleaning device is placed on the long nozzle 6;
3) open the quick lock in knob, pass into oxygen;
4) residual molten steel on long nozzle 6 inwalls melts after meeting oxygen, and is under the effect of air-flow, that the molten steel purging of fusing is clean.
This kind is used for the cleaning quality that the large Quick cleaning device that wraps long nozzle has improved long nozzle greatly; reduced simultaneously scavenging period; for condition has been created in direct casting; the shutdown loss of having avoided improper owing to cleaning or having had little time it is pressed for time to cause; Simultaneous Stabilization steel stream; reduce the product quality objection that causes thus, improved product quality.
