Abstract

The invention belongs to the technical field of steel rolling and discloses a method for preventing strip steel from buckling in an annealing furnace. The method for preventing the strip steel from buckling in the annealing furnace includes the steps that the minimum running speed is controlled, and the running speed of the strip steel in the annealing furnace is controlled to be larger than or equal to the minimum running speed; the minimum running speed Vmin= V(w/Thi) X Fv(w) X fv(opt_strip_temp), Fv(w) is a minimum running speed _width coefficient, and fv(opt_strip_temp) a minimum running speed _temperature coefficient; V(w/Thi) is a minimum running speed cardinal number and is solved through V(w/Thi)=(1-sigma/sigma a) x Vmax; and Vmax is a theoretical maximum production speed accordingto the specification, sigma is unit tension, and sigma a is critical tension. The method for preventing the strip steel from buckling in the annealing furnace is provided, it is achieved that the strip steel buckling risk is substantially reduced, and the strip steel quality stability is improved.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a method for preventing buckling of strip steel in an annealing furnace. Background technique [0002] Lid opening accidents are very common in steel rolling production, and usually refer to unplanned furnace lid opening, which seriously affects the annealing and the ability of the strip steel production line to run stably. The main reason is that the strip bends in the annealing furnace, which leads to unplanned opening of the furnace lid. However, there is a lack of effective targeted solutions in the prior art. Contents of the invention [0003] The invention provides a method for preventing strip steel from buckling in an annealing furnace, and solves the technical problem that the strip steel is easy to buckle in an annealing furnace in the prior art. [0004] In order to solve the problems of the technologies described above, the invention provides a method for pr...
