Description
Technical Field
The invention belongs to the field of steel production, in particular to an electrode quick-release device for a ladle refining furnace, which belongs to the field of refining furnace equipment.
Background
Ladle refining furnaces (LF refining furnaces) are the most common external refining means in the metallurgical industry, and mainly rely on graphite electrodes to heat and slag molten steel in a ladle. The three-phase graphite electrode is fixed on the three-phase electrode cross arm through an electrode clamp and an electrode clamp hydraulic cylinder. The electrode cross arm is driven by an electrode lifting hydraulic cylinder to lift. The electrode is composed of an electrode hanging ring and a graphite electrode body in production and use, as shown in fig. 1 and 2.
In the production process, the graphite electrode is continuously lost in the process of heating the molten steel in the ladle. The electrode cross arm continuously descends under the driving control of the electrode lifting hydraulic cylinder so as to keep the heating state of molten steel. When the electrode is worn to some extent, the following occurs: the electrode transverse arm descends to the lower limit position of the stroke and still cannot contact the liquid level of molten steel in the ladle, so that heating cannot be performed. At this time, the following operations must be performed: the electrode is firstly moved out of the ladle to loose the electrode, and then the electrode is moved into the ladle to be heated continuously.
In the prior art, the electrode loosening operation adopts a cantilever crane (crane) to hang the electrode to be loosened, then an electrode clamp is opened, the cantilever crane (crane) is operated to descend, the electrode to be loosened is placed to a proper length, and finally the electrode clamp is clamped to complete the whole electrode loosening operation. The loose electrode has at least the following three defects:
first, the operation needs to be operated by means of cantilever crane (especially, part of enterprises need to use travelling crane), and the loose electrode is longer in use, so that the production rhythm can be influenced.
Secondly, the electrode clamp is affected by human factors, and the electrode clamp is opened and is not a loose electrode, so that the electrode is dropped and broken, production is affected seriously, and even accidents such as furnace return and casting breaking are caused.
Thirdly, the cantilever crane (crane) lifting hook is connected with the electrode lifting ring through shackles or steel wire ropes, personnel are required to climb the electrode cross arm when each time of electrode loosening, the electrode is respectively connected with the electrode to be loosened, but the personnel repeatedly climb the electrode arm and the electrode arm to have larger risk of falling injury, the electrode is in a red hot state in the production process, scalding is easy to cause, and meanwhile, the shackles and the steel wire ropes are required to be replaced frequently to prevent accidental breakage.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which can be made by a person skilled in the art without creative efforts, based on the described embodiments of the present invention fall within the protection scope of the present invention.
Unless defined otherwise, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs.
The following are embodiments of the present invention, which are described as only a few embodiments of the present invention, and all other embodiments that can be obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present invention.
The invention is further illustrated by way of example with reference to the accompanying drawings. The electrode quick-release device of the ladle refining furnace is shown in figures 1-5. The electrode body 5 may be a graphite electrode body in general. The electrode body 5 is fixed on the electrode cross arm 1 through the electrode clamp 2, and the electrode lifting hydraulic cylinder 3 is in driving connection with the electrode cross arm 1.
Referring to fig. 3, the electrode cross arm 1 is provided with an electrode cross arm travel upper limit 16 and an electrode cross arm travel lower limit 17, and the electrode cross arm travel upper limit 16 and the electrode cross arm travel lower limit 17 are mutually matched. As shown in fig. 3-4, the buggy ladle 7 is arranged on the ladle lane rail 9, and the buggy ladle 7 is provided with a ladle 13 and an electrode supporting platform 8 which are matched with the electrode body 5.
In an embodiment of the invention, referring to fig. 3-4, the electrode support platform 8 is secured to a support frame 14. In the embodiment, the bracket 14 is connected or welded on the buggy ladle 7 by adopting high-strength square steel.
Referring to fig. 5, the electrode supporting platform 8 may be made of a 45# steel plate, and refractory bricks are laid at supporting points of the three electrode bodies corresponding to the loose electrode positions on the supporting surface, and fireproof paint is poured around the refractory bricks. The buggy ladle track 9 is provided with a buggy ladle sitting limit 10, a buggy ladle Che Song electrode limit 11 and a buggy ladle processing limit 12. The ladle car seat limit 10, the ladle Che Song electrode limit 11, the ladle car treatment limit 12, the electrode cross arm travel upper limit 16 and the electrode cross arm travel lower limit 17 can be common mechanical limit or induction limit.
Exemplary method of operation:
in normal production, the buggy ladle 7 firstly receives the ladle 13 at the ladle seating position. After receiving the ladle 13, the ladle car 7 moves to the processing position. Then, the refining furnace cover 15 descends to the edge of the ladle 13, and then power can be transmitted. Subsequently, as shown in fig. 3, the electrode bridge 1 descends, and the three-phase graphite electrode body 5 contacts with molten steel to heat the molten steel.
When the electrode body 5 is consumed to some extent, an electrode replacement operation is required. According to an embodiment of the invention, it is first confirmed that the electrode is located at the upper limit of travel and the refining furnace lid 15 is located at the upper limit. Subsequently, the ladle carriage 7 is moved to the loose electrode position, as shown in fig. 4, where the electrode support platform 8 of the ladle carriage 7 is located directly below the electrode. Thereafter, the electrode bridge 1 is operated to descend until the lower end of the electrode falls on the electrode support platform 8. Thereafter, the electrode clamp 2 is opened, and the electrode bridge 1 is operated to rise to a proper height. Generally, the distance between the electrode supporting platform 8 and the electrode clamp 2 is smaller than or equal to the length of the two electrode bodies 5, so as to prevent the ladle 13 from breaking the electrode when the buggy ladle 7 is driven into the processing position due to the excessive distance. Finally, the electrode clamp 2 is clamped to complete the loose electrode operation of the current phase electrode.
In an embodiment, the above operation may be repeated as necessary to loosen the other electrode body 5.
After the whole electrode body 5 is loosened, the electrode body 5 is lifted to an upper limit 16 of the travel of the electrode cross arm, a furnace cover 15 of the refining furnace is lifted to an upper limit, and the ladle car 7 is moved to a treatment position or a ladle seating position as required.
The foregoing is merely illustrative of the embodiments of this invention and it will be appreciated by those skilled in the art that variations and modifications may be made without departing from the principles of the invention, and it is intended to cover all modifications and variations as fall within the scope of the invention.
