The invention provides a rapid strip connection device and method for a broken steel strip in a suspension curing furnace, and belongs to the technical field of suspension curing furnace equipment and using methods. The rapid strip connection device and method are used for rapid strip connection of the broken steel strip in the suspension curing furnace. According to the technical scheme, steel stranded wires are embedded in the two sides of the steel strip in the suspension curing furnace, the two ends of each steel stranded wire are located at the two outer ends of the suspension curing furnace, and broken steel strip punching devices are arranged inside and outside the suspension curing furnace correspondingly. After the steel strip is broken in the suspension curing furnace, the broken steel strip is pulled out towards the two ends, the two ends of the steel stranded wires are connected with the broken steel strip segments at the two ends correspondingly, and then the connected broken steel strip segments are pulled out of the furnace to one side for further treatment. According to the rapid strip connection device and method for the broken steel strip in the suspension curing furnace, the structure is simple and compact, and operation is easy and fast; the broken steel strip in the suspension curing furnace can be handled rapidly on the premise that the furnace is not stopped, the maintenance time is shortened to one hour or less from the original several hours, the accident handling time is greatly shortened, the production efficiency is improved, and remarkable economic benefits are achieved.
