Abstract
This invention disclose a kind of anti-deflection alarm system used in continuous vertical annealing oven. It includes tension alarm module including tension modification protection module, used to identify whether annealing oven meets the first permanent condition or not, whether annealing oven meets the first initial condition. When annealing oven meets the first permanent and initial conditions, the alarm will be triggered. The differential temperature alarm module is used for the temperature difference of plate and area, the anti-deflection equipment is used to monitor and control cold state deflection limit specification, the steel belt transition alarm module is used to specification transition alarm, temperature transition alarm and hot roller alarm during oven starting, the speed alarm module is used to identify whether annealing oven meets the second permanent condition: production mode class 2, or present oven speed is maintained continuously for 2h >= Alpha, and whether annealing oven meets the second initial condition: the present oven speed < minimum operation speed; when annealing oven meet the second permanent condition and initial condition at the same time, the alarm will be triggered.
Description
technical field [0001] The present application relates to the technical field of steel rolling, in particular to an anti-bending alarm system applied in a continuous vertical annealing furnace. Background technique [0002] After the chilled coil is heated to a certain temperature in the annealing furnace, the yield strength decreases sharply. For example, after the DC03 brand strip is heated from 200°C to 800°C, the yield strength Rp0.2 decreases from 493MPa to 14MPa. At this time, the strip steel in the furnace is easy to receive the temperature difference and the transverse compressive stress generated by the tension in the width direction, resulting in buckling deformation, see figure 1 . Often when the tension or temperature in the furnace is abnormal, the operator cannot find out in time that the strip is bent and broken in the furnace. Among the 68 unplanned openings of the Shougang Jingtang Cold Rolling Department from 2009 to 2015, 30 unplanned openings were cause...
