Abstract

An inlet sealing device used for an annealing furnace is provided. The inlet sealing device comprises sealing rollers disposed at the inlet of the annealing furnace. The sealing rollers are respectively disposed at the lower parts of two vertically disposed supports. An air cylinder is disposed between the two supports, and is separately connected to the upper parts of the supports through a connecting rod device. The supports are driven to rotate around rotating shafts disposed at the middle parts of the supports by the connecting rod device driven by the air cylinder, so as to drive the two sealing rollers to adjust the roller gap between the two sealing rollers. A handle adjusting assembly is disposed at the outside of each of the supports. The positions of the two handle adjusting assemblies are corresponding to each other. A sealing plate assembly is disposed in a gap between each of the sealing rollers and a furnace shell at the inlet of the annealing furnace. The inlet sealing device separates the atmosphere in the furnace from the atmosphere outside the furnace and prevents scratch defects on surfaces of steel. The sealing plate assemblies are disposed between the roller surfaces and the furnace shell and are adjustable in position. The inlet sealing device is suitable for the field of inlet sealing of various annealing furnaces in process sections of galvanization units.
