Abstract

The invention discloses a ladle rotary table, aiming to provide a steelmaking continuous casting equipment in the metallurgical industry. The invention has the functions of automatically rotating, lifting, adding a heat preservation cover, and weighing the ladle; the invention is provided with a rotary support device , lifting device, and heat preservation cover device. In the technical solution of the present invention, the slewing support device uses three rolling element assemblies to provide support for the inner hole of the supporting ring gear and its end face, and has a large ability to withstand the tilting moment. The lifting device is provided with a parallelogram The connecting rod structure can keep the ladle in a vertical state during the lifting process, and the double transmission box device is used to provide power for the rotation of the two heat preservation covers; the technical scheme of the invention can make the ladle rotate smoothly and the braking efficiency is high And the braking reliability is good, the anti-tipping moment load is large, which can effectively overcome the damage to the transmission chain caused by the reverse impact movement, the ladle lifting action is stable and the lifting position is accurate and controllable, the impact of the weighing device is small, and the ladle is covered and moved Reliable action and accurate rotary positioning, compact structure.

Description

technical field [0001] The invention relates to steelmaking and continuous casting equipment in the field of metallurgical machinery, in particular to a ladle turret. Background technique [0002] The ladle turret is the equipment for carrying and supporting the ladle for pouring in the continuous casting of the steelmaking plant. It is set between the molten steel receiving span and the pouring span. The two ends of the swivel arm carry the ladle. The steel ladle rotates half a circle, stops above the tundish (or tundish), releases molten steel for continuous casting, and the poured empty ladle is rotated half a circle through the rotary table, and then transported back to the molten steel receiving span. At present, there are single-arm ladle turrets and butterfly ladle turrets in use in China, especially butterfly ladles, which are convenient for continuous pouring of multiple furnaces because they can quickly replace ladles. However, the above-mentioned ladle turret gen...
