Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel strip production, and particularly relates to a straightening, descaling and guiding device for stainless steel strip after annealing. Background Technique

[0002] When producing stainless steel strips, in order to obtain high-quality excellent products, the annealed stainless steel strips need to be transported to other equipment for processing through conveyor rollers; however, the strips are prone to deviation when being conveyed on the conveyor rollers. Therefore, a straightening, descaling and guiding device for stainless steel strip after annealing is needed, which can smoothly guide the strip into the subsequent processing device and prevent production accidents such as equipment damage and strip breakage.

[0003] After retrieval, there is a flat steel hot rolling guiding device with the publication number of CN 218486876 U in the prior art. This device can perform guiding operations on the passing flat steel through the provided first guiding device and second guiding device. And since both the first guiding device and the second guiding device can be adjusted up and down, guiding operations can be carried out for flat steel with different thicknesses during production; however, the friction and a large amount of frictional heat generated during the movement of the strip will accelerate the damage of the device; and when replacing the damaged structure inside the device, the structure inside the device can only be disassembled and replaced after the machine is stopped.

[0004] After retrieval, there is a hot rolled strip guiding mechanism with the publication number of CN 217798100 U in the prior art. This device fixes and installs the guiding insert through a detachable pin. When the guiding insert is damaged and needs to be replaced due to long-term use, the guiding insert can be removed and replaced only by manually operating the detachable pin; the problem of this device is also that the damaged components inside the device need to be replaced after the machine is stopped.

[0005] Therefore, a straightening, descaling and guiding device for stainless steel strip after annealing is needed, which can protect the structure inside the device, extend the service life of the device, and at the same time can replace the damaged components under the condition that the equipment is operating normally.
