Abstract
The utility model relates to a billet connecting piece of a steelmaking and continuous casting billet heat exchanger, which comprises a circular ring and an inverted conical upright column; and the billet connecting piece is characterized in that a twisted steel is bent into a circular ring shape and welded to form the circular ring, the inverted conical upright column comprises six twisted steels, one ends of the six twisted steels are evenly distributed on the circumference of the circular ring and respectively fixed by welding in a matched manner, and the adjacent twisted steels at the other end are respectively fixed by welding in a matched manner, so as to form the inverted conical billet connecting piece. The utility model has the benefits that the continuous casting heat exchange effect can be realized rapidly, the rapid heat exchange of the tundish is realized, and the industrial accident caused by pull-out or bleed-out during the heat exchange is avoided.
Description
Technical field
The utility model relates to field of steel-making, the hot changing device steel billet of especially a kind of steel-making continuous casting base connector.
Technical background
The work of continuous casting tundish has certain service life, use arrival during the life-span at the continuous casting tundish, the operation of two kinds of selection modes is arranged usually, A: under the not compact situation of rhythm of production or because of equipment fault have to place under repair or when the periodic inspection task is arranged casting machine select to leave behind operation.B: in the rhythm of production compactness, output pressure is big, and when not having plant issue not have the maintenance task, selects tundish heat to change usually.This operation can be saved strand and left behind casting machine downtime; effectively improve the casting machine operating efficiency; but change in the process in tundish heat; the molten steel in mold top of freezing to death is easily caused next tundish molten steel not have molten steel and is broken away from, and two cast steel billets break away from up and down; steel billet in the crystallizer is not connected; can't continuous pouring, can cause usually strand in the crystallizer with after pour into the disengaging or the bleed-out of crystallizer molten steel, seriously restrict continuous casting heat and change operation.
Summary of the invention
The technical problems to be solved in the utility model is, now design a kind of steel structure connecting member, the interior strand of crystallizer effectively is connected with the molten steel that next tundish is flowed down, prevents that the molten steel that strand and next tundish are flowed down in the crystallizer breaks away from, and reduces heat and changes failure.
The utility model solves its technical problem, the technical scheme of being taked is: be made up of annulus and back taper column, spiral is bent into circular welding and constitutes annulus, the back taper column is made up of six roots of sensation spiral, six roots of sensation spiral one end cooperates solid welding with the annulus circumference uniform distribution, the other end faces spiral mutually and cooperates solid welding, constitutes back taper steel billet connector.
The utility model compared with the prior art, its beneficial effect is, can realize fast that continuous casting heat changes effect, realizes that the tundish Rapid Thermal changes, and stops to take off or bleed-out causes production accident because of thermal metathesis.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model structure chart,
Fig. 2 is the vertical view of the utility model Fig. 1.
The specific embodiment:
The utility model is to realize like this, form by annulus and back taper column, spiral is bent into circular welding and constitutes annulus 1, the back taper column is by six roots of sensation spiral 2,3,4,5,6 form, six roots of sensation spiral 2,3,4,5,6 one ends cooperate solid welding with annulus 1 circumference uniform distribution, six roots of sensation spiral 2,3,4,5,6 other ends face spiral mutually and cooperate solid welding, constitute back taper steel billet connector, cone tip part with this steel billet connector during use vertically inserts in the crystallizer molten steel down, when next Baogang's water injects crystallizer, freeze on steel billet connector top, and steel billet is combined together.
