Description
Technical Field
The utility model belongs to the technical field of metallurgical equipment, especially, relate to a tight device in continuous casting ladle long nozzle top.
Background
The realization of non-oxidation pouring in the continuous casting process is important to reduce inclusions in steel and improve the purity of molten steel and the quality of casting blanks. An important part of the continuous casting non-oxidation pouring technology is to protect the steel flow from the ladle to the tundish from secondary oxidation, and in the process, the steel flow is usually poured by using a ladle long nozzle seal. During the pouring process, because of the rapid flowing of the molten steel, negative pressure is formed near the long nozzle bowl, and air is sucked in to oxidize the molten steel. In order to avoid air suction, in addition to argon blowing protection near the bowl portion, the tightness of the contact portion between the long nozzle bowl portion and the ladle sliding nozzle is also extremely important.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a tight device in continuous casting ladle long nozzle top, the technical scheme who adopts as follows: the utility model provides a tight device in continuous casting ladle long nozzle top which characterized in that: the device is provided with a simple manual hydraulic jack, a common strip-shaped thin steel plate is welded at the top of a plunger of the manual hydraulic jack, and a steel ferrule is welded at the middle position of the upper surface of the strip-shaped thin steel plate; the bottom of the manual hydraulic jack is welded and fixed on a common thick steel plate, and the common thick steel plate is fixed at a proper position of a ladle casting platform by using two foundation bolts; a thin iron ring is also arranged, and the upper end of the thin iron ring is provided with a hook ring; the lower end of the thin iron ring is arranged in the steel ferrule in a penetrating way, and the hook ring at the upper end of the thin iron ring is connected with the hook at the middle position of the handle of the ladle long nozzle holder. The plunger of the manual hydraulic jack is stretched to drive the ladle long nozzle holder to move up and down, so that the ladle long nozzle is tightly supported and fixed.
The utility model discloses simple structure, low in cost, the tight control in top of the long mouth of a river of realization continuous casting process ladle that can be fine does benefit to product quality's promotion.
