Description

Technical Field

[0001] The utility model relates to the technical field of annealing furnace production, in particular to a broken strip cooling device for a horizontal annealing furnace. Background Art

[0002] Strip breakage in the annealing furnace refers to the phenomenon that the steel strip breaks in the annealing furnace due to various reasons during the process of heating and cooling the steel strip in the annealing furnace. It is necessary to take out the cooled half of the steel strip from the outlet, and then take out the other half of the broken steel strip from the entrance. The strip breakage in the annealing furnace takes a long time to process, produces a lot of scrap steel, and affects the production capacity of the continuous annealing line.

[0003] The high-temperature annealing furnace cover accelerated cooling device disclosed in the existing patent announcement number CN214142468U is provided with an annealing furnace cover, a buffer cylinder and a filter screen. When the annealing furnace cover needs to be cooled, the cooling pipe and the air outlet pipe are connected to the annealing furnace, and the gas is introduced into the two cooling pipes through a high-speed fan. The gas enters the annealing furnace cover through the cooling pipe to cool the annealing furnace cover. As the gas gradually enters the annealing furnace cover, it will accumulate in the annealing furnace cover. When the gas cools the annealing furnace cover, the temperature will gradually increase, and the high-temperature gas will flow upward, so it will be discharged from the air outlet pipe. When the gas is discharged, it will take away part of the ash in the annealing furnace cover. If the gas is discharged directly, it will have a bad impact on the environment. The gas is guided to the filter barrel through the air outlet pipe, and is blocked by the buffer cylinder. The gas can only enter the inside of the buffer cylinder from the through hole and flow upward. At this time, the gas can be initially filtered through the through holes, and larger impurities will fall outside the buffer cylinder. Subsequently, the gas enters the buffer cylinder through the slag discharge port, diffuses upward, and is double filtered by the filter and sponge block to reduce the amount of impurities and dust in the gas, and then is discharged from the air outlet to reduce the amount of impurities in the discharged gas. After long-term use, when the filtering effect of the filter and sponge block deteriorates, the air outlet part is rotated and removed. At this time, the compression block is separated from the sponge block, and the sponge block and filter can be removed, which is convenient for cleaning and replacement, and the ash in the buffer cylinder can be cleaned.

[0004] In actual factory use, the above device requires no less than two groups of annealing furnaces to work. If a broken strip needs to be processed, the steel strip remaining in the furnace needs to be pulled out from the furnace inlet and outlet respectively. However, due to the extremely high temperature of the steel strip, a fixed cooling device is installed at the outlet of each annealing furnace. If the broken steel strip is directly pulled out from the entrance, it will be affected by the heating section, which will not only cause burns to personnel, but also damage the entrance roller. In view of the above problems, a broken strip cooling device for a horizontal annealing furnace is proposed. Utility Model Content
