Abstract

The invention provides a method and device for improving tension control stability of an annealing furnace. By increasing the original unit tension, the unit tension of the interior of the annealing furnace during production is obtained; the standard surface roughness threshold value of a tension roller is obtained; the surface roughness of the tension roller is controlled to be within the standard surface roughness threshold value; a tension roller load balancing factor is adjusted; and by increasing the unit tension of the interior of the annealing furnace, the tension roller load balancingfactor is adjusted, the surface roughness of the tension roller is controlled to be within the standard surface roughness threshold value, and the tension stability of the annealing furnace is controlled. The technical problem that in the prior art, a tension roller cannot provide the sufficient balance force, and thus, stable operation of strip steel cannot be ensured is solved. The technical effects that control over the tension of the annealing furnace is achieved, the tension balancing capacity of the tension roller is improved, it is ensured that the tension roller can provide enough balance force, the risk of slipping of the tension roller is avoided, the control stability of tension of the interior of the annealing furnace is greatly improved compared with the original design, and the production requirements are completely met are achieved.

Description

technical field [0001] The invention relates to the technical field of cold rolling automatic control, in particular to a method and a device for improving the tension control stability of an annealing furnace. Background technique [0002] The steel strip of the cold rolling processing line is usually operated under slight tension in the annealing furnace. The radial pressure of the tension roller at the exit of the zone is very small, and the friction force that the tension roller can provide to the strip to maintain stable tension is small. However, in order to ensure the running stability of the strip steel, the tension of the strip steel is very high except in the furnace area, and there is a large tension difference between the front and back of the tension roller, which requires a large balance force provided by the tension roller, which aggravates the risk of the tension roller slipping. At the same time, in order to improve the surface quality of the strip steel, c...
