Steel ladle turret

Abstract

The invention discloses a steel ladle turret, and aims at providing metallurgical industry steel making continuous casting equipment. The steel ladle turret has the functions a steel ladle is automatically rotated, lifted and weighed, and heat insulating covers are automatically added to the steel ladle. The steel ladle turret is provided with a rotating supporting device, a lifting device and a heat insulating cover device. In the technical scheme, in the rotating supporting device, three rolling body assemblies are adopted for supporting a supporting gear ring inner hole and the end face thereof, and the capacity of bearing overturning moment is high; and the lifting device is provided with a parallelogram connecting rod structure, the steel ladle can be always kept in a vertical state in the lifting process, and a double-transmission-box device is adopted for providing power for rotation of the two heat insulating covers in a centralized manner. By the adoption of the technical scheme, the steel ladle can be stably rotated, the braking efficiency is high, the braking reliability is good, the overturning torque resistant load is large, damage of reverse impact movement to a transmission chain can be effectively overcome, the steel ladle is stably lifted, the lifting position is accurate and controllable, impact of a weighing device is low, cover adding and removing actions ofthe steel ladle are reliable, the steel ladle is rotated and positioned accurately, and the structure is compact.

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...

AI Technical Summary

Problems solved by technology

However, the above-mentioned ladle turret generally has a complex structure, the working environment temperature of the main hydraulic cylinder is too high, the oil leakage is serious, the braking effect is not good, the reverse movement impact is easy to cause damage to the transmission chain, and the insulation cover device has a complicated structure and takes up a lot of space. , equipment installation is difficult, equipment investment costs are high, etc.
