Problems solved by technology

This method of on-site construction has high labor intensity for the workers, and the working environment and working conditions are extremely harsh. Especially when the flue wall is burned and then removed and rebuilt, not only the temperature is high and the dust is large, but also the working space of the roaster is limited, which is inconvenient. Construction, the masonry time is long, which not only affects the safety of the builders, but also seriously affects the quality and work efficiency of the masonry flue wall

Abstract

This invention is a carbon roaster flame path wall building method. It includes procedurals such as wall building, integral swing and spot assembly. There is lifting platform outside of the roaster. The flame path wall swing frame is arranged on the platform. The flame path wall body is built in the frame. The frame and flame path wall are swung together to the corresponding position of roaster by lifting equipment. After falling on the ground, the frame board is unloaded and plastered with fire-proof ash to fix the flame path wall. This invention not only improves constructing environment, but also reduce the working intensity of workers. This invention greatly shortens the troubleshooting time of roaster and increases the manufacturing efficiency.

Description

technical field [0001] The invention belongs to the technical field of roasting furnaces for producing carbon products for aluminum electrolytic cells, and in particular relates to a method for building a flue wall of a carbon roasting furnace by masonry. Background technique [0002] Over the years, the masonry of the flue wall of the carbon roasting furnace has been completed by workers in the deep pit of the furnace chamber. This method of on-site construction has high labor intensity for the workers, and the working environment and working conditions are extremely harsh. Especially when the flue wall is burned and then removed and rebuilt, not only the temperature is high and the dust is large, but also the working space of the roaster is limited, which is inconvenient. Construction, the masonry time is longer, which not only affects the safety of the builders, but also seriously affects the quality and work efficiency of the masonry flue wall.
