Annealing device for cold-rolled stainless steel machining line

Abstract

The invention discloses an annealing device for a cold-rolled stainless steel machining line. The annealing device comprises a box body, a PLC, an electromagnetic heating coil and a circulating water channel, an operation panel is arranged on one side wall of the box body, and a box opening is formed in one end of the box body. The annealing device has the beneficial effects that through the design of a liquid storage box, a refrigerator, a first pump machine and a circulating pipeline, the annealing device can be cooled through water cooling, the annealing cooling operation of the device does not need to consume a large amount of time, and therefore the working efficiency of the device is improved; through the design of the box body and a draught fan, the annealing device can have an air flow assisting function, air in the device can circulate, thus, it can be ensured that cold-rolled stainless steel is heated evenly, and the annealing effect of the device is improved; and through the arrangement of a second pump machine and a drainage pipe, the annealing device can have a waste heat recovery function, the heating temperature of the device can be subjected to heat recovery, and therefore energy waste can be avoided.

Description

technical field [0001] The invention relates to the technical field of annealing devices, in particular to an annealing device for a cold-rolled stainless steel processing line. Background technique [0002] Cold-rolled stainless steel refers to cold-rolled steel sheets, which are steel sheets produced by cold rolling. Cold rolling is a steel plate in which the steel plate is further thinned to a target thickness at room temperature. Compared with hot-rolled steel sheets, the thickness of cold-rolled steel sheets is more accurate, and the surface is smooth and beautiful, and it also has various superior mechanical properties, especially in terms of processing performance. Because cold-rolled raw coils are relatively brittle and hard, they are not suitable for processing. Usually, cold-rolled steel sheets are required to be annealed, pickled, and surface smoothed before being delivered to customers. An annealing device is required during the annealing process.

AI Technical Summary

Problems solved by technology

[0003] Most of the existing annealing devices adopt natural cooling, which leads to a large amount of time-consuming annealing and cooling operation of the device, resulting in low working efficiency of the device. At the same time, most of the existing annealing devices do not have the function of air-assisted flow, resulting in that the air in the device cannot Circulation, which will easily cause the cold-rolled stainless steel to be heated unevenly, which will affect the annealing effect. Moreover, the existing annealing device does not have the function of waste heat recovery, resulting in the heating temperature of the device cannot be used for heat recovery, resulting in unnecessary waste of energy. Therefore be badly in need of a kind of cold-rolled stainless steel processing line annealing device to solve existing problems
