Problems solved by technology

[0003] In the current stainless steel annealing and pickling line, the motor in the pickling line usually runs at the rated speed. When thin material is produced, as the thickness of the steel strip produced becomes smaller, the speed of the motor can no longer be increased after reaching the rated speed. Continue to improve, so that the production capacity of the production line cannot be released

Abstract

The invention provides a stainless steel sheet annealing and pickling line acceleration method and system. The method comprises the steps that the maximum speed of a to-be-processed steel belt in thefeeding area and the maximum speed of the to-be-processed steel belt in the discharging area are calculated, specifically, the maximum speed of the to-be-processed steel belt in the feeding area and the maximum speed of the to-be-processed steel belt in the discharging area are calculated according to the preset acceleration of the feeding area, the preset technological processing speed of the technological processing area, the length of the to-be-processed steel belt, the preset deceleration of the discharging area and the head-tail welding time of the to-be-processed steel belt and an adjacent to-be-processed steel belt in the feeding area in a pickling line, and the numerical value of the preset deceleration of the discharging area is equal to that of the preset acceleration of the feeding area; and parameters of a frequency converter are corrected, specifically, the parameters of the frequency converter in the pickling line are corrected according to the maximum speed of the feeding area and the maximum speed of the discharging area, and the frequency converter is used for conducting frequency conversion speed regulation on a motor in the feeding area and a motor in the discharging area so that the pickling line can conduct production according to the preset technological processing speed.

Description

technical field [0001] The application belongs to the technical field of producing stainless steel plates, and in particular relates to a method and system for increasing the speed of an annealing and pickling line for stainless steel plates. Background technique [0002] The pickling line is a technological process in iron and steel metallurgy, the purpose is to remove the oxide scale on the steel strip, and obtain a strip steel with a clean surface for further rolling of the steel strip. Its technological process usually includes: feeding, process treatment (mainly including decoiling, welding, pickling, passivation, cutting, etc.), and unloading. [0003] In the current stainless steel annealing and pickling line, the motor in the pickling line usually runs at the rated speed. When thin material is produced, as the thickness of the steel strip produced becomes smaller, the speed of the motor can no longer be increased after reaching the rated speed. Continue to improve, ...
