Abstract
The utility model relates to the field of steel-making continuous casting, in particular to a continuous casting machine dummy bar head avoiding steel welding. The continuous casting machine dummy bar head comprises a dummy bar dovetail groove and is characterized in that one or two connecting beams are arranged in the dummy bar dovetail groove according to different continuous casting machine types, the width of the connecting beams ranges from 50 mm to 70 mm, and the upper surfaces of the connecting beams are flush with the upper edge of the dummy bar dovetail groove. The connecting beams are distributed in the center of the dummy bar dovetail groove or at the symmetrical positions on the two sides of the central axis of the dummy bar dovetail groove. Compared with the prior art, the continuous casting machine dummy bar head has the advantages that safety accidents possibly caused by manually cutting dummy bar transition chain bolts by cutters in the process of welding the dummy bar head are effectively avoided, dummy ingot stripping basically succeeds at a time after improvements, the serious production accident of clamping casting blanks by a continuous casting machine due to welding of the dummy bar head is effectively reduced, the accuracy of continuous casting machine equipment is guaranteed, normal pouring in the dummy ingot stripping process of the continuous casting machine can be carried out, the pulling rate does not need to be lowered, and the quality of the casting blanks is improved.
Description
Technical field
The utility model relates to steel-making continuous casting field, relates in particular to a kind of dummy bar of continuous casting machine head of avoiding welding steel.
Background technology
Along with the development of iron and steel technology, improving conticaster operating rate is each plant design conticaster dominant direction.Existing 3 the VAI conticasters of Bayuquan steel-making portion, the mode of its dress dummy bar is upper dress mode, upper dress dummy bar mode can effectively shorten conticaster and pour into a mould interval time, greatly improve conticaster production operational availability, but in actual production, reclaiming dummy bar device must design at teeming stage, follow closely on bar chassis the success rate of this gesture necessary guarantee deingot to drawing by hoisting dummy bar.If opening strand head and dummy head while watering welds together, causing cannot successful deingot, casting machine must be reduced to pulling rate below 0. attached m/min, to ensure that fiery cut has the sufficient time manually to cut the bolt of dummy bar transition chain, even but like this, the time that fire cut manually cuts dummy bar transition chain bolt is also shorter, about 3 minutes.Because the technical merit height of each production team differs, cause unavoidably manual cutting dummy bar transition chain bolt failure, this will certainly cause the production accident of conticaster folder base, upsets original production schedule.According to statistics, its to open flow welding dummy bar be to be welded in the position that is connected with dummy bar dovetail groove centre in the middle of strand head substantially entirely.
Summary of the invention
The purpose of this utility model is to provide a kind of dummy bar of continuous casting machine head of avoiding welding steel, reduces and opens the generation of flow welding dummy bar phenomenon, thereby avoided opening the ratio that waters deingot failure, guaranteed the security of producing and can continuity.
For achieving the above object, the utility model is achieved through the following technical solutions:
A dummy bar of continuous casting machine head of avoiding welding steel, comprises dummy bar dovetail groove, for different continuous casting types, 1～2 place's tie-beam is set in dummy bar dovetail groove, and the width of tie-beam is 50～70mm, and the upper surface of tie-beam is upper along concordant with dummy bar dovetail groove.
Described tie-beam is distributed in the middle position of dummy bar dovetail groove or the symmetric position of both sides, axis.
Compared with prior art, the utility model beneficial effect is:
Effectively avoid cutting because weldering dummy head causes the security incident that work is manually cut dummy bar transition chain bolt and likely cause, reduced workman's labour intensity, ensured workman's safety; After improvement, substantially eliminate weldering dummy head phenomenon, realize full-automatic deingot success, effectively reduced conticaster because weldering dummy head causes the pernicious production accident of conticaster folder base, guaranteed the precision of continuous casting machine, potential productivity effect is considerable; In conticaster deingot process, can normally pour into a mould, not need to reduce again pulling rate, so also improve the permanent pulling rate rate of conticaster, improve the quality of strand.

In figure: 1-dummy bar 2-dovetail groove 3-tie-beam
Detailed description of the invention
Face is not described further detailed description of the invention of the present utility model by reference to the accompanying drawings:
See Fig. 1, Fig. 2, a kind of dummy bar of continuous casting machine head embodiment that avoids welding steel of the utility model, mainly by reducing the connection area ratio between strand head and dummy bar dovetail groove, reduce the weld strength of strand head and dummy bar, for different continuous casting types, 1～2 place's tie-beam 3 is set in the dovetail groove 2 of dummy bar 1, and the width of tie-beam 3 is 50～70mm, and the upper surface of tie-beam 3 is upper along concordant with the dovetail groove of dummy bar 2.
For the small-sized conticaster type of 1.5～1.8m in embodiment, tie-beam 3 is distributed in the middle position of the dovetail groove 2 of dummy bar.And for the large-scale continuous casting machine type of 1.8～2.3m, tie-beam 3 can arrange two, is distributed in the symmetric position of both sides, axis of the dovetail groove 2 of dummy bar.
The utility model ensure original open water before prepare prerequisite under, by changing the contact area rate of strand head and dummy bar dovetail groove middle part, effectively reduce the phenomenon of opening flow welding dummy head, thereby effectively avoided the problem of a series of safe, the production, equipment and the slab quality that cause due to weldering dummy head.
Claims (2)
