Problems solved by technology

[0002] The suspended cylinder of Maerz kiln with suspended cylinder has been in a high temperature working environment above 1150°C for a long time, especially the base of the suspended cylinder is easy to be damaged. When the base of the suspended cylinder is damaged, it is easy to cause the upper refractory brick to sink, and even the whole kiln collapses danger, so production had to be shut down for maintenance
However, the current Maerz lime kiln suspension tank repair technology is not yet mature, and the repaired Maerz lime kiln suspension tank will be damaged after a short period of use

Description

Technical field: [0001] The invention relates to a method for repairing the base of a hanging cylinder of a Maerz lime kiln. Background technique: [0002] The suspended cylinder of Maerz kiln with suspended cylinder has been in a high temperature working environment above 1150°C for a long time, especially the base of the suspended cylinder is easy to be damaged. When the base of the suspended cylinder is damaged, it is easy to cause the upper refractory brick to sink, and even the whole kiln collapses danger, and had to be shut down for maintenance. However, the current Maerz lime kiln suspension tank repair technology is not yet mature, and the repaired Maerz lime kiln suspension tank will be damaged again after a short period of use. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the existing technical defects and provide a method for repairing the base of the suspended cylinder of a Maerz lime kiln. [0004] Th...
