Abstract
The utility model relates to a continuous casting tundish for reducing steel remaining quantity, belonging to the technical field of continuous casting devices in metallurgy industry. The continuous casting tundish for reducing the steel remaining quantity comprises a tundish body and a tundish base, wherein a nozzle brick is arranged at the tundish base; a tilted structure is arranged at the tundish base at one side facing the steel surface in the tundish body; and the periphery of the tilted structure close to the nozzle brick is lower and the part where the tundish base is close to the tundish body is higher. The continuous casting tundish for reducing the steel remaining quantity has the characteristics of being simple, convenient and feasible for operation and the like, can be applied to the continuous casting tundish, and can reduce the remaining steel quantity after the final pouring of the tundish due to the effect of the tilted structure of the tundish body so as to enhance the molten steel yield and reduce the manufacturing cost. By utilizing the continuous casting tundish for reducing the steel remaining quantity, the steel remaining quantity of the tundish can be controlled at about 1 ton at each time, and the blank output can be increased by about 1.5 tons at each pouring time relative to the traditional tundish, and the molten steel yield of a continuous casting blank is enhanced.
Description
Technical field
The utility model relates to the continuous casting tundish that the steel amount is stayed in a kind of minimizing, belongs to metallurgy industry continuous casting installation for casting technical field.
Background technology
At present, it is horizontal that steel plant use the bag Bottom Shape of continuous casting tundish to be mainly, and both sides, little slag weir are horizontal, mainly is that under the less situation of molten steel, molten steel confuses slag and flows into crystallizer when preventing that tundish from watering eventually.But, the tundish of this shape and structure, tundish waters the back tundish eventually and stays the steel amount generally all more than 2 tons, influences the molten steel recovery rate of continuous casting billet, has increased process cost in actual mechanical process at the bag end.How guaranteeing that crystallizer does not descend under the situation of slag when tundish waters eventually, the steel amount of staying that reduces tundish is the technical barrier that this area needs to be resolved hurrily.
Summary of the invention
The purpose of the utility model patent provides the continuous casting tundish that the steel amount is stayed in a kind of minimizing, guarantee that crystallizer not descend under the prerequisite of slag, that reduces tundish stays steel amount, reduction process cost, improve the molten steel recovery rate of continuous casting billet, solve the problems referred to above that background technology exists.
The technical solution of the utility model is: the continuous casting tundish of steel amount is stayed in a kind of minimizing, comprise at the bottom of inclusion and the bag, bag is provided with pocket block in the end, and meeting in the inclusion at the bottom of the bag of steel face one side is incline structure, this incline structure is lower around close pocket block, and is higher near the part of inclusion at the bag end.
Meeting in the inclusion at the bottom of the bag of steel face one side is incline structure, and its angle of inclination is the 25--30 degree, and the molten steel that makes tundish meet the steel side can water.
This incline structure is lower around close pocket block, is the center with the pocket block, forms the bath of 1 meter of a diameter, prevents to pour into a mould later stage volume slag and enters crystallizer.
The utility model is an incline structure at the bottom of can just making the bag of meeting steel face one side in the inclusion when tundish is made, also can transform existing flat tundish.
The utlity model has characteristics such as simple to operate, conveniently feasible, all can implement, because the incline structure effect at the bag end can be lacked the residual steel amount after tundish waters eventually, improve the molten steel recovery rate of strand, the reduction manufacturing cost at the continuous casting tundish; After adopting the utility model, the residual steel amount of tundish can be controlled at about 1 ton at every turn, and each waters and time can become about 1.5 tons of bases more with respect to original tundish, has improved the molten steel recovery rate of continuous casting billet.
Description of drawings
Accompanying drawing is the utility model example structure schematic diagram;
Among the figure: inclusion 1, the bag end 2, pocket block 3, incline structure 4, bath 5, stopper 6, last slag weir 7, following slag weir 8.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, the continuous casting tundish of steel amount is stayed in a kind of minimizing, comprises the inclusion 1 and the bag end 2, the bag end, be provided with pocket block 3, meeting in the inclusion at the bottom of the bag of steel face one side is incline structure 4, and this incline structure is lower around near pocket block, and is higher near the part of inclusion at the bag end.Meeting in the inclusion at the bottom of the bag of steel face one side is incline structure, and its angle of inclination is the 25-30 degree, is shown as 30 degree among the figure, and the molten steel that makes tundish meet the steel side can water.This incline structure is lower around close pocket block, is the center with the pocket block, forms the bath 5 of 1 meter of a diameter, prevents to pour into a mould later stage volume slag and enters crystallizer.
Present embodiment is that existing flat tundish is transformed, remodeling method: with at the bottom of the bag of meeting steel face one side of tundish on original basis whole bed hedgehopping tilt to the molten bath, at the bottom of original bag with in the middle of the bed hedgehopping part, be connected with stamp mass with solid matter 6# steel wire, prevent layering, the bed hedgehopping part is transformed into the oblique angle of 30 degree to a side of stopper 6 in steel flow, the molten steel that makes tundish meet the steel side can water, and around stopper, be transformed into a molten bath about diameter 1m, prevent to pour into a mould later stage volume slag and enter crystallizer.Improved tundish has used 12 times, and each waters and time on average stays 0.945 ton of steel amount, has reached Expected Results.
