Abstract
The utility model belongs to the improvement, especially a dummy ingot structure of modified continuous casting sizing start crystallizer of the dummy ingot structure of the little billet casting sizing of steel mill start crystallizer, including and installing the dummy ingot head in the downthehole cooperation of the dummy ingot of crystallizer, be located the overhead dummy ingot guide arm that is setting up of the downthehole dummy ingot of crystallizer dummy ingot, the equipartition is setting up upright screw thread round steel around the dummy ingot guide arm, and the diameter of screw thread round steel is 12mm, and the length and the dummy ingot head dummy bar length of screw thread round steel suit. The utility model discloses simple structure, practicality, easily processing can be eliminated to open and water drawing of molten steel and dummy ingot head and take off the phenomenon, improves the success rate of continuous casting start, can reduce workman's intensity of labour, improvement work efficiency.
Description
Technical field
The utility model belongs to the dummy ingot structure of the continuous casting sizing start crystallizer of the improvement, particularly a kind of improvement of the dummy ingot structure of steel mill continuous small-billet casting sizing start crystallizer.
Background technology
Steel mill continuous small-billet casting sizing placingJi Shu is a new technology, and being does not need stopper but rely on mouth of a river internal diameter to control the pouring procedure of the molten steel flow injecting crystallizer.This method advantage is: do not need stopper and stopper control mechanism, decrease resistance to material expense and equipment and spare part expense, and metering nozzle flow-control is relatively stable, is conducive to the raising of continuous casting billet quality.Meanwhile, can automatic casting be realized, reduce worker's labour intensity.
The cast of tradition steel plant continuous casting sizing is after dummy bar head is sent into crystallizer, copper pipe surrounding in crystallizer is dried up, then at the gap place jam-pack asbestos cord of dummy bar head surrounding post crystallization device copper pipe, then arranges the cold burden of 10-12mm with interleaved mode.
The subject matter existed is as follows:
1, cold burden needs length more single, 10-12mm, needs to process specially.
2, easily cause " bridgings " phenomenon when molten steel pours crystallizer when starting shooting, namely molten steel does not enter cold burden Lower Half and is connected with dummy bar head, and molten steel directly solidifies at the cold burden first half, easily causes molten steel and dummy bar head to pull, cause the accident during withdrawal straightening machine startup.
Utility model content
The purpose of this utility model is the dummy ingot structure of the continuous casting sizing start crystallizer providing improvement, and its structure is simple, practical, is easy to processing, can eliminate open water molten steel and dummy bar head pull phenomenon, improve the success rate of continuous casting start, the labour intensity of workman can be reduced, increase work efficiency.
The purpose of this utility model is achieved in that a kind of dummy ingot structure of continuous casting sizing start crystallizer of improvement, coordinate in the dummy ingot hole being included in crystallizer and dummy bar head is installed, the dummy bar head being positioned at crystallizer dummy ingot hole arranges dummy ingot guide rod, the surrounding of dummy ingot guide rod is uniform arranges upright screw thread round steel, the diameter of screw thread round steel is 12mm, and length and the dummy bar head dummy bar length of screw thread round steel adapt.
It is as follows that the utility model mainly improves content:
1, screw thread round steel is bundled into wisp, vertically puts into around crystallizer dummy ingot guide rod.
2, screw thread round steel length adaptability is comparatively large, and material prepares easily.
Main improvement effect:
(1) threaded circular steel construction is simple, and applicability is strong, and material is easy to processing, and producing cost is less.
(2) eliminate after screw thread round steel being set around dummy ingot guide rod open water molten steel and dummy bar head pull phenomenon, improve the success rate of continuous casting start.
(3) effectively reduce the labour intensity of workman, greatly improve the working environment of workers.
The utility model structure is simple, practical, is easy to processing, eliminate open water molten steel and dummy bar head pull phenomenon, improve the success rate of continuous casting start, reduce the labour intensity of workman, improve operating efficiency.
Accompanying drawing explanation
Be further described the utility model below in conjunction with accompanying drawing, Fig. 1 is perspective view of the present utility model.
Detailed description of the invention
A kind of dummy ingot structure of continuous casting sizing start crystallizer of improvement, as shown in Figure 1, coordinate in the dummy ingot hole being included in crystallizer 1 and dummy bar head 2 is installed, the dummy bar head 2 being positioned at crystallizer 1 dummy ingot hole arranges dummy ingot guide rod 3, the surrounding of dummy ingot guide rod 3 is uniform arranges upright screw thread round steel 4, the diameter of screw thread round steel 4 is 12mm, and length and dummy bar head dummy bar 3 length of screw thread round steel 4 adapt.
Claims (1)
1. the dummy ingot structure of the continuous casting sizing start crystallizer improved, coordinate in the dummy ingot hole being included in crystallizer (1) and dummy bar head (2) is installed, it is characterized in that: the dummy bar head (2) being positioned at crystallizer (1) dummy ingot hole arranges dummy ingot guide rod (3), the surrounding of dummy ingot guide rod (3) is uniform arranges upright screw thread round steel (4), the diameter of screw thread round steel (4) is 12mm, and length and dummy bar head dummy bar (3) length of screw thread round steel (4) adapt.
