Anti-collision device for ladle sliding nozzle mechanism

Abstract

The invention relates to an anti-collision device for a ladle sliding nozzle mechanism. The anti-collision device comprises a supporting rod, a supporting flange and a connecting contact, and is arranged in the sliding nozzle mechanism, wherein the sliding nozzle mechanism comprises a fixed frame, an opening and closing frame, a sliding frame and an oil cylinder support; one end of the supporting rod is fixed with the connecting contact through threads, and the other end of the supporting rod passes through a locking nut and is connected with the supporting flange through threads; the supporting flange is connected with the oil cylinder support; and the connecting contact is connected with a connecting rod head on the sliding frame. The anti-collision device has a reasonable structure and high safety, is easy to operate, avoids the phenomenon that a nozzle is abnormally opened due to accidental collision of the sliding nozzle mechanism in the running process of a ladle, prevents serious malignant production accidents caused by outflow of molten steel during steel tapping, ensures normal running of steelmaking production, and is an ideal matching product for collision prevention, safe running and upgrading and reconstruction of the conventional ladle sliding nozzle mechanism.

Description

technical field [0001] The invention relates to the technical field of steelmaking equipment, in particular to an anti-collision device for a ladle sliding nozzle mechanism. Background technique [0002] In modern steelmaking production, the ladle sliding nozzle mechanism is an important control component in steelmaking equipment. It is used to realize the pouring of molten steel in the ladle. After the molten steel is poured, the ladle is cleaned and replaced at the hot repair station. , and then continue to be put into normal production turnover. The ladle is run to the tapping station of the smelting furnace and the steel receiving operation is completed, then it is transferred to the next station and the refining operation outside the furnace is completed, and then it is again transferred to the continuous casting station for For the pouring operation of molten steel, the ladle completes a cycle. [0003] During the recycling process of the ladle, from the hot repair st...

Problems solved by technology

[0004] When the ladle is running through the ladle car, the sliding nozzle mechanism is located at the bottom of the ladle, and the lowermost nozzle and movable guard plate of the sliding nozzle mechanism are closest to the ground where the ladle car is walking, generally 150 mm to 250 mm, due to the unevenness of the ground and With the existence of obstacles such as steel slag, it is difficult to avoid the collision of such obstacles on the sliding nozzle mechanism, especially the lower nozzle and movable guard plate located at the bottom of the sliding nozzle mechanism. Once such obstacles hit the lower nozzle or movable guard plate, It will drive the sliding frame to move together with the lower plate, so that the sliding nozzle is opened and is in the state of steel pouring, and it is not easy to be found by the operator. In this way, when the ladle is receiving steel under the smelting furnace, the hot molten steel at 1600°C will flow from the ladle nozzle Direct leakage, burning out equipment such as ladle cars, sliding nozzle mechanisms, and walking tracks, resulting in interruption of steelmaking production, huge economic losses, and serious consequences
