Description
Technical field
The present invention relates to make steel the RH technology field, be specifically related to a kind of technological design scheme of RH vacuum treatment installation.
Background technology
Along with the development of Chinese national economy, the user constantly enlarges the demand of rolling shapes, to the also raising day by day of requirement of steel product quality.From technology itself and experience, RH is that the vacuum-treat technology has become a kind of expansion product scope, one of the effective means of improving the quality of products.
There is the technological design scheme of multiple patterns such as single station, double and ladle be rotary in the existing RH vacuum treatment installation of domestic each steel mill.These technological design schemes generally are arranged on the processing position of RH vacuum treatment installation that the steelshop liquid steel refining is striden or molten steel accepts to stride (following explanation is striden with liquid steel refining and is example), RH ladle car track and vacuum chamber trolley replacing track are arranged vertically, reducing the place longitudinal length, and structure and equipment design are simple; Other material loading, charging system and vacuum pump system etc. are arranged on steelshop converter bay or auxiliary striding in (following explanation is example with the converter bay) contour striding.There is the problem of three aspects in this usually for increasing the RH vacuum treatment installation of building in the existing steelshop.It is not enough or do not reserve the RH place that the first aspect steelshop is reserved RH place transverse width, can not satisfy 2 and handle position and 2,3 or 4 width for the treatment of the seat in the plane are provided with requirement; Second aspect steelshop liquid steel refining is striden or molten steel is accepted to stride crane rail level absolute altitude deficiency, can not satisfy the requirement for height that is provided with that RH handles the position top blow oxygen lance; Third aspect steelshop converter bay is not considered large crane, can not satisfy the needs of vacuum chamber handling.Just need seek a kind of new technological design scheme this moment.
Summary of the invention
Technical problem to be solved by this invention is: the RH vacuum processing technique layout pattern that provides a kind of RH ladle car track and vacuum chamber trolley replacing parallel track to arrange, reserve RH place transverse width deficiency or do not reserve the RH place to satisfy steelshop, liquid steel refining is striden or molten steel accepts to stride crane rail level absolute altitude deficiency, converter bay is not considered under the situations such as large crane, build or newly-built steelshop in increase and build the RH vacuum treatment installation, the needs that enlarge the steel products kind and improve the quality of products.
The present invention solves its technical problem and adopts following technical scheme:
The lateral arrangement of ladle car track provided by the invention and vacuum chamber trolley replacing parallel track, it is to adopt following method to realize the lateral arrangement of RH ladle car track and vacuum chamber trolley replacing parallel track in the RH system, its step comprises:
It is vertical that RH ladle car track and steelshop are respectively striden, and pass through converter bay, liquid steel refining is striden accepts to stride with molten steel;
RH is handled the position be arranged in the RH ladle car track of converter bay, arrange RH ladle jacking framework, RH buggy ladle and ladle, vacuum chamber trolley replacing and vacuum chamber and top blow oxygen lance from bottom to up successively;
In the ladle car track both sides platform post is set, utilizes these platform posts, on vertical height, set gradually each layer platform to support aforesaid device.
The lateral arrangement of RH ladle car track and vacuum chamber trolley replacing parallel track in the above-mentioned realization RH provided by the invention system, its reserves the application when not enough of RH place transverse width solving steelshop; Perhaps stride or molten steel is accepted to stride crane rail level absolute altitude deficiency at liquid steel refining, can not satisfy RH handle the position top blow oxygen lance requirement for height is set the time application; Perhaps do not consider large crane, the application in the time of can not satisfying the needs of vacuum chamber handling at converter bay.
The present invention compared with prior art has following major advantage:
1. reduce that the steelshop liquid steel refining is striden or molten steel is accepted to stride crane rail level absolute altitude, reduce investment outlay;
2. adapt to the condition that steelshop is reserved place transverse width deficiency or do not reserved the place, for the new RH vacuum treatment installation of going up creates conditions;
3. refining cycle is short, satisfies the high efficiency continuous casting machine and produces needs.

Embodiment
The invention provides the RH vacuum processing technique arrangement that RH ladle car track and vacuum chamber trolley replacing parallel track are arranged, it adopts RH ladle car track and vacuum chamber trolley replacing parallel track to arrange.The vacuum chamber of handling the position in the steelshop converter bay is treated seat in the plane (change bit) by the steelshop refining that longitudinally moves to of vacuum chamber trolley replacing in striding when needs are changed tubular stinger, the large crane of striding with refining hangs vacuum chamber and changes.Perhaps reach to solve and reserve lateral length insufficient problem in place in the steelshop.And RH is handled the position be arranged in converter bay, reduced the requirement of refining being striden crane rail level absolute altitude, reach the best processing route equally.
The invention will be further described below in conjunction with embodiment and accompanying drawing.
The present invention adopts following method to realize the lateral arrangement of RH ladle car track and vacuum chamber trolley replacing parallel track in the RH system, and as shown in Figure 1 to Figure 3, its step comprises:
