Tension stabilizing device for band steel in continuous annealing wire annealing furnace

Abstract

The invention relates to a strip steel tension stabilizing device in an annealing furnace on a continuous annealing line. A swing frame is articulated with a base. Two fixed steering rollers which are separated at intervals are arranged on the base. A motor is fixed on the swing frame. A bearing base is arranged on the surface of the swing frame. An output shaft of a reducer is connected with a regulating screw. Guiding rods are arranged on the two sides of the regulating screw. A slider is connected with the regulating screw in a screwing way. The slider is connected with the guiding rods in a sliding way. A lifting guidance roller is arranged on the swing frame. A horizontal displacement sensor is fixed on the bearing base. The end part of a telescopic link of the horizontal displacement sensor is connected with the slider. The lower end of a guiding board is articulated with the base by a lower fixed shaft. A vertical displacement sensor is fixed on the guiding board. An upper fixed shaft is fixed on the swing frame. The end part of a telescopic link of the vertical displacement sensor is arranged on the upper fixed shaft. The strip steel tension stabilizing device in the annealing furnace on the continuous annealing line realizes the real-time detecting control on the tension changes in the annealing furnace and provides accurate control parameters for controlling the stability of the strip steel tension in the furnace.

Description

technical field [0001] The invention relates to a tension stabilizing device for strip steel in an annealing furnace of a continuous annealing line for thin stainless steel strips. Background technique [0002] The tension in the annealing furnace of the stainless steel continuous annealing line directly affects the annealing quality of the strip steel. For thin stainless steel strips with a thickness of less than 0.2mm, it is required to keep the tension of the steel strip in the annealing furnace stable during work. furnace loss. If the tension is less than the set value, the strip steel is easy to rub against the bottom of the furnace, causing the surface of the strip steel to be scratched, and the strip steel is scrapped. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a tension stabilization device for strip steel in the annealing furnace of the continuous annealing line for stainles...
