Problems solved by technology
[0003] During the annealing process, a layer of oxide scale will be deposited on the surface of the steel strip. The conventional method is to knock the oxide scale off the surface with a tool hammer. This operation method is because the long strip steel is not easy to store, and the second is the knocking operation. Can cause severe deformation of the strip, resulting in increased labor costs when the strip is converted to stainless steel in subsequent processes

The invention provides a stainless steel plate annealing and cooling device which comprises a supporting rod and an annealing cabin arranged at the top end of the supporting rod, a fan is arranged at the bottom of the annealing cabin, an exhaust hood is arranged at an air outlet of the fan, and a large air hole communicated with an inner cavity of the annealing cabin is upwards formed in the middle of the bottom face of the annealing cabin. The top end of the exhaust hood is connected to the bottom face of the annealing cabin and communicated with the large air hole, an electric cylinder is fixed to the side portion of the annealing cabin, the push plate is an arc-shaped plate, the push plate is located in the annealing cabin, the arc bending degree of the push plate is consistent with that of the annealing cabin, and oxide skin is forced to fall off downwards along with continuous compression action. Limiting plates which are located on the inner sides of the push plates and used for forming the internal and external clamping effect on the strip steel together with the push plates are further arranged in the annealing cabin, rotating supporting blocks are arranged on the peripheries of the limiting plates, and when the supporting blocks rotate, another compression mechanism is just formed on the inner side of the steel coil, so that the strip steel is compressed from inside to outside, and the oxide skin falling efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of heat treatment and annealing, in particular to a stainless steel plate annealing cooling device. Background technique [0002] Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, holding it for a sufficient time, and then cooling it at a suitable rate. The purpose is to reduce hardness and improve machinability; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grains, adjust structure, and eliminate structure defects. After heat treatment, strip steel also needs to be annealed according to the above principles, and then After phosphating and descaling treatment, it is put into product processing. [0003] During the annealing process of the strip steel, a layer of oxide scale will be precipitated on the surface. The conventional practice is to knock off the oxide scale by hitting the surface with a tool ha...
