Abstract
The utility model discloses a tundish impact zone slag blocking wall. A protective plate in an impact zone and the slag blocking wall are formed to be an integral shape, and the corners of the impact zone are totally surrounded by the slag blocking wall. The slag blocking wall is easier and more convenient to install and can be directly placed according to the position of the impact zone, the corners in the weak link are surrounded by the integral protective plate, a tundish is safer and more reliable in use, and the problem that bleed-out appears due to the fact that the corners are seriously scoured by molten steel can not appear. Meanwhile, steel flowing holes at different inclined angles are formed in the side face of the slag blocking wall, therefore, the molten steel flows upward, the retention time of the molten steel in the tundish is prolonged, the flow field of the molten steel is changed, and the slag blocking wall can play a role in purifying the molten steel. The slag blocking wall can be made of high-alumina materials or aluminum-silicon materials or aluminum-magnesium materials or magnesium materials.
Description
Technical field
The utility model relates to a kind of structure, particularly a kind of structure of whole slag blocking wall of molten steel in bakie in continuous casting impact zone of steel-making continuous casting tundish flow control equipment.
Background technology
Tundish develops into the number of different types structure so far, but wherein T-shaped tundish bag type is still main flow, by molten steel impact zone He Jiaogang district, formed, be provided with difform slag blocking wall and carry out flow control between molten steel impact zone Yu Jiaogang district, reached the effect in molten steel specific flow field in tundish.So; the impact zone of this type tundish is all narrower, and when large Baogang comes under water, molten steel acutely seethes at this; each face of impact district especially the corner in impact zone Yu Jiaogang district wash away, corrode very serious, so generally at each face of impact zone, all be provided with backplate protected.But construction is comparatively loaded down with trivial details like this, not only will post backplate, also must coordinate with the slag blocking wall of front finely, so just can prevent that corner from infiltering molten steel, working layer is herein washed away totally, cause centre free clothing steel accident.
Summary of the invention
The purpose of this utility model is to provide a kind of easy-to-install tundish impact area slag blocking wall, simplifies the construction installation method of current slag blocking wall herein, better protects impact zone.
The technical solution of the utility model is: the backplate at tundish impact area place and slag blocking wall are made to an integral body, and it is shaped as directly accomplishes the backplate originally be attached to separately on working lining on slag blocking wall, and fits like a glove with the impact zone turning.It is characterized in that: backplate and slag blocking wall are made an integral body, have simplified construction method, and main is the corner that has surrounded impact zone Yu Jiaogang district fully, has avoided molten steel to be penetrated into herein, cause and wash away the steel accident of wearing caused because of working lining.
The utility model and existing slag blocking wall technology relatively have the remarkable advantage that uses safety, long service life, and greatly simplify operational procedure.The material of slag blocking wall can be High-Alumina or alumina-silica or magnalium matter or magnesia.
The accompanying drawing explanation
Fig. 1 is the longitudinal sectional drawing that slag blocking wall is placed in tundish impact area.
Fig. 2 is the top view that slag blocking wall is placed in tundish impact area.
Fig. 3 is the top view of the utility model tundish impact area slag blocking wall.
In figure, 1 is the permanent layer castable, the 2nd, and refractory material for working layer, the 3rd, impact zone flow straightener, the 4th, impact zone slag blocking wall, the 5th, tundish overfall.
The specific embodiment
The T-shaped tundish that loyal two workshops are moistened in Jiangsu Sha Gang group company is five machine five stream caster tundish, and its slag blocking wall material is magnesian, is shaped as slag blocking wall and backplate and makes an integral body.By both merging, the corner that is close proximity to impact zone Yu Jiaogang district fitted like a glove, be close to working layer, simplified the program of construction, avoid molten steel to wash away this zone simultaneously, guaranteed the safe handling of tundish, the service life of also greatly having improved tundish, this tundish, by 12 hour original service time, is brought up to 16 hours.
Claims (3)
1. a tundish impact area slag blocking wall, it is characterized in that: the backplate of tundish impact area position and slag blocking wall are made to a global shape, and impact zone corner is all surrounded by slag blocking wall.
2. a kind of tundish impact area slag blocking wall as claimed in claim 1, it is characterized in that: with impact zone corner working lining near slag blocking wall on have steel outlet hole, respectively there is up and down one, upper steel outlet hole aperture Φ 100-200mm, inclination angle 10-30 °, lower steel outlet hole aperture Φ 100-200mm, inclination angle 20-40 °.
3. a kind of tundish impact area slag blocking wall as claimed in claim 1, it is characterized in that: its material can be High-Alumina or alumina-silica or magnalium matter or magnesia.
