Abstract
The utility model relates to an anti-blowing upper water nozzle for continuous-casting middle ladles, which is provided with a sheet steel anchor ear on the middle lower part of an upper water nozzle body. The utility model has the advantages that anti-blowing upper water nozzle for continuous-casting middle ladles not only reinforces and improves the strength of the middle lower part of an upper water nozzle after the middle lower part of the upper water nozzle body is covered with the sheet steel anchor ear, but also reduces the temperature difference between the upper part and the lower part of the upper water nozzle body when used. Consequently, the utility model effectively prevents the lower half part of the upper water nozzle from blowing when used.
Description
Technical field
The utility model relates to the tundish upper nozzle in the steel-making continuous casting equipment.
Background technology
By the tundish upper nozzle that refractory material is made, it is installed on continuous casting tundish bottom, and its first half is positioned at tundish, the outstanding outside, tundish bottom that is exposed to of Lower Half.Therefore in casting process, have the bigger temperature difference between its first half and the Lower Half, and produce different swelling stresses, thereby mouth of a river Lower Half bursts phenomenon and happen occasionally, have a strong impact on normal safety in production.
Summary of the invention
The technical problem that the utility model quasi-solution is determined is: for the continuous casting tundish provides a kind of filling pipe end that is difficult for bursting.
Technical solution of the present utility model is: establish the steel disc anchor ear in filling pipe end body middle and lower part.
The beneficial effects of the utility model are, filling pipe end body middle and lower part jacket behind the steel disc anchor ear, not only reinforce and improved filling pipe end middle and lower part intensity, and in use dwindled the temperature difference between the filling pipe end body top and the bottom, thereby prevented that effectively the filling pipe end Lower Half from use bursting.
Description of drawings
Accompanying drawing is that the utility model is installed in the general structure schematic diagram on the tundish.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
By the continuous casting tundish upper nozzle 2 that refractory material is made, the outside, bottom is sheathed with steel disc anchor ear 4 therein, and the steel plate thickness of anchor ear 4 is preferably the 0.1-1.0 millimeter.When the utility model is installed on continuous casting tundish 1 bottom, be sheathed with the outstanding outside, tundish bottom that is exposed to, middle and lower part of steel disc anchor ear section, the top of steel disc anchor ear section is positioned at middle water containing opening brick cup 3.
Claims (2)
1, a kind of continuous casting tundish upper nozzle of anti-cracking is characterized in that being provided with the steel disc anchor ear in filling pipe end body middle and lower part.
2, by the continuous casting tundish upper nozzle of the described anti-cracking of claim 1, the steel plate thickness that it is characterized in that the steel disc anchor ear is the 0.1-1.0 millimeter.
