Description

Technical Field

[0001] The invention relates to the technical field of converter masonry, and in particular to a converter masonry auxiliary device. Background Art

[0002] Most of the existing converters are built by building a furnace tower. The furnace service time is generally 96±2 hours. The problems with this furnace building method are: first, the furnace building time is long, resulting in an overall furnace service period of more than 16 days, seriously affecting the converter operation rate; second, there are major safety hazards. Since the furnace tower itself weighs 20 tons, it is lifted from the spare position to the lower furnace by a 32-ton crane in the factory, passing through other production furnace seats, with a large span and a long distance. In order not to affect production, it needs to be lifted from 46 meters and needs to pass through 4 platforms. If someone is working below or there is a fall during the lifting process, it will directly cause equipment damage or threaten personal safety.

[0003] In order to solve the above problems, this patent proposes a converter masonry auxiliary device. Summary of the invention
