Abstract
The present invention is refining steel ladle hoisting method and rotating bench unit and belongs to the field of external molten steel refining technology. The method of the present invention includes hoisting two refining steel ladles onto two refining benches on the same support, and completing the refining operation in one of the two refining steel ladles and the pre-refining operation in the other one simultaneously. Completing hoisting refining steel ladle and refining simultaneously can omit the waiting time and raise the production efficiency.
Description
Technical field
The invention belongs to the external refining molten steel with supplementary unit and application method thereof, refer in particular to and hang commentaries on classics ladle method and refining ladle turn around table thereof in the ladle refining process in the refining.
Background technology
Traditional steelmaking process is divided into refining just and two steps of refining carry out, electric furnace, the ladle refining technology is generally adopted in converter steelmaking, the molten steel that will just refine in converter or electric furnace is poured into and is carried out deoxidation in ladle or the special container, desulfurization, decarburization, degas, remove non-metallic inclusion and adjustment molten steel component and temperature to reach the process for making of further smelting purpose, the refining task of soon in conventional steel melting furnace, finishing, as remove impurity and (comprise unwanted element, gas and be mingled with), adjust task with even composition and temperature, partly or entirely move on in ladle or other containers and carry out, in the hope of obtaining Clean Steel and obtaining high yield, high-quality, good result cheaply.
In traditional ladle refining process, ladle is opened to refining furnace through buggy ladle and to be carried out refining after just having produced steel, and after refining finished, refining ladle is left to winch to the continuous casting operation by driving and descend continuous casting working procedure one.In this technological process, buggy ladle is left the operation process of buggy ladle being left after finishing to refining furnace and refining, all need a large amount of non-cutting times that ladle or refining furnace are operated, and the refining station only has one, refining operation need be waited for finishing of each non-productive operation operation, comprise changing over to of ladle, produce, feed, pull out rare gas element etc., carrying out ladle after refining finishes hangs when changeing operation, refining operation stops, wasted the refining time of ladle, so the very difficult raising of the production efficiency of refining procedure, so that influence carrying out smoothly of next process continuous casting.
Summary of the invention
The purpose of this invention is to provide to hang in a kind of refining and change ladle method and refining ladle turret device thereof, it adopts the refining platform station mode that increases, make full use of the ladle refining time, take handling ladle and refining ladle process to carry out mode simultaneously, all kinds of non-cutting times have been reduced, satisfied the demand that the molten steel Argon stirs and smelts, for refining and continuous casting cooperatively interacts, the production direct motion provides guarantee.
For achieving the above object, the technical solution used in the present invention is as follows:
Hanging in a kind of refining changes the ladle method, it is characterized in that will hanging in turn the commentaries on classics ladle places on the two refining platforms of same support, this support supports with rotary table and can rotary table serve as that axle rotates, ladle on the refining platform is wherein being carried out purified simultaneously, and another refining platform changes the ladle operating process over to before finishing refining; After ladle was finished refining on the last refining platform, when producing the ladle operation, another refining platform ladle changed over to, carried out the refining operation circulation.
Further say, hang the method for changeing ladle in this refining, it is characterized in that this method comprises following concrete steps:
Ladle is after just having produced steel, and the buggy ladle operation puts in place, pulls out inert gas tube, ladle is hung on the wherein refining platform that goes to the refining ladle turn around table;
This refining platform is plugged inert gas tube, feed rare gas element and stir;
Change this refining turn around table over to ladle and carry out refining, simultaneously another ladle is hung on the second refining platform that goes to the refining ladle turn around table;
After ladle refining finished on the last refining platform, this refining turn around table hung out ladle, pulls out inert gas tube;
This ladle is winched to continuous casting from the refining turn around table;
Simultaneously the second refining platform is plugged inert gas tube, open rare gas element and stir, ladle on this refining platform is carried out refining.
Rare gas element in the described ladle refining process is an argon gas.
Change the non-productive operation that hangs in and feed inert gas tube that the ladle operation comprises ladle before the described refining over to.
Described refining platform produces the non-productive operation that hangs out and pull out inert gas tube that the ladle operation comprises ladle.
A kind of refining ladle turret device comprises rotary table, revoliving arm and refining platform, it is characterized in that setting up on the rotary table revoliving arm, and two refining platforms are positioned on this revoliving arm and lay respectively at its end positions.
Described rotary table is positioned at two refining platform mid-ways.
Each refining platform all is provided with the pipeline of a logical rare gas element.
Two refining platforms adopt welding process to be fixed on the rotary support respectively.
Two refining platforms of this refining ladle turret device are positioned at the rotary support two ends, and rotary support is positioned on the rotary table, but rotary support changes base rotation in 360 degree together with two refining platform wraparounds.This refining turret device has two refining stations, and so wherein the ladle on the refining platform carries out purified simultaneously, and another refining platform can be finished and enter preparation work before the refining procedure, and what comprise ladle hangs in, feeds inert gas tube etc.; After the refining process of a refining platform is finished, it is hung out ladle turret when entering continuous casting operation process, another refining platform can enter refining procedure.Like this, the refinery practice process can be carried out continuously, can not delay the carrying out of refining work because of the purified back work, more can not influence the work of next process process continuous casting.
Beneficial effect of the present invention is, the refining ladle turn around table has two refining stations in this method and apparatus, two stations can hang respectively and change ladle and refining ladle two procedures, therefore hanging commentaries on classics ladle and refining ladle process can carry out simultaneously, all kinds of non-cutting times have been reduced, avoided the generation of refining furnace idle waiting situation, and then provide guarantee smoothly for producing.
Description of drawings
The invention will be further elaborated below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of apparatus of the present invention embodiment.
Embodiment
As figure, this refining ladle turret device comprises two refining platforms 1 and 4, rotary support 2, and rotary table 3, refining platform 1 is connected and fixed on the two ends of rotary support 2 respectively with refining platform 4 front and back with bolt, and all has logical rare gas element mouth 5 on each refining platform.Rotary support 2 is fixed on the rotary table 3, and rotary table 3 is positioned at two refining platforms 1 and refining platform 4 mid-ways, its can drive rotary support 2 and on refining platform 1 rotate in 360 degree with refining platform 4, turn to convenient two refining platforms.
This refining turret device has two refining stations, and when so wherein the ladle in the refining platform carried out refining operation, another turn around table can be finished and enter the preceding preparation work of refining procedure; Simultaneously, the ladle refining process in a refining platform is finished, and it is hung out ladle turret when entering the continuous casting operation, and another refining platform can change over to and carry out refining procedure.
