Description

Tipping device of molten steel tank

Technical Field

The utility model relates to the field of metallurgical technology equipment, in particular to a tipping device of a molten steel tank.

Background

In order to ensure the quality and safety of molten steel casting, a steel mill needs to replace a sliding plate in a sliding nozzle on the bottom of a molten steel tank after casting a plurality of ladles of molten steel when using the molten steel tank, and sometimes needs to maintain and replace the sliding nozzle and an argon blowing device at the bottom of the molten steel tank. After the maintenance work is completed, the residual steel in the ladle must be poured out. The hot repair of the upper molten steel tank is realized by tipping the molten steel tank, most tipping work of a steel mill is completed by a crown block, and a molten steel tank tipping device adopting a motor reducer form and a common transmission mode is also provided. The work of tumbling is accomplished by the overhead traveling crane, and the fly hook of overhead traveling crane catches on ladle both sides trunnion, and the main hook catches on the ladle lifting hook and drives the ladle and use the trunnion as the fulcrum rotation, and the whole action is realized slowly, and the working cycle is long, and is inefficient, and occupies the overhead traveling crane for a long time, influences the production efficiency in whole steelmaking workshop. The steel ladle tipping device adopting the common transmission mode has large occupied area and high cost.
