An automatic anti-deviation device and automatic anti-deviation method for annealing furnace rollers

Abstract

The present invention provides an automatic anti-deviation device and automatic anti-deviation method for annealing furnace rolls. The device includes a bellows and an adjustment box fixed on the bottom of the bellows; It is connected to the air inlet hole of the adjusting box, and an eccentric cover plate is installed at the air inlet hole through a rotating shaft, and the rotating shaft is fixed on the bottom surface of the adjusting box; a disc is sleeved on the rotating shaft, and the disc circumscribes a pair of symmetrically arranged moving bars; Each moving bar is arranged along the axial direction of an air supply duct; a guide groove for accommodating the moving bar is set on the air supply duct; one side of the moving bar extends into the air supply duct; both ends of the moving bar pass through springs It is fixed in the air supply pipe; the gas flow in the pair of air supply pipes is opposite; the pair of air supply pipes are located in the regulating box; one end of the pair of air supply pipes is located outside the regulating box. In the present invention, the protective gas can be regulated after the box is adjusted to reduce the waste of the protective gas, which is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of furnace roll crown control, and in particular relates to an automatic deviation prevention device and an automatic deviation prevention method for furnace rolls of an annealing furnace. Background technique [0002] Continuous annealing furnace is usually divided into preheating section, heating section, soaking section, slow cooling section, fast cooling section, overaging section, final cooling section and water quenching section. The diameters of the furnace rollers in the furnaces of different process sections are different. The strip steel in the continuous annealing furnace is driven by the furnace roller under the action of tension to complete the entire annealing process. In order to prevent the strip steel from being oxidized during heating, the annealing furnace is a closed space. Once the strip steel deviates in the furnace, if it is not detected in time, the deviation of the strip steel will ...

AI Technical Summary

Problems solved by technology

However, because the cold protective gas is directly introduced into the heat insulation space, the inflow of the cold protective gas cannot be controlled, and there is a phenomenon of waste of the cold protective gas.
