Problems solved by technology
The furnace door set on the existing annealing furnace for the steel strip to pass out is an arched door, affected by the temperature of the steel strip, the existing furnace door is easy to collapse and damage
Moreover, the opening of the existing arched door is relatively large, and the furnace pressure in the annealing furnace is not stable enough due to the influence of the air entering the furnace door.

The invention provides a furnace door structure of an annealing furnace. The furnace door structure comprises the annealing furnace; a furnace door is arranged at the rear end of the annealing furnace; the furnace door comprises an upper furnace door and a lower furnace door; the upper furnace door and the lower furnace door are arranged oppositely from top to bottom; the upper furnace door is provided with a first driving device for driving the upper furnace door to move up and down; the lower furnace door is provided with a second driving device for driving the upper furnace door to move upand down; the first driving device and the second driving device are used for synchronously driving the upper furnace door and the lower furnace door to move in a face-to-face direction or an oppositedirection, so that a furnace door opening between the upper furnace door and the lower furnace door is reduced or enlarged. According to the furnace door structure, the size of the furnace door opening can be adjusted, and the aim of regulating and controlling the air inlet amount in the annealing furnace is realized by utilizing the size of the furnace door opening, so that the furnace pressurein the annealing furnace is stable and adjustable.
Description
technical field [0001] The present invention relates to Steel belt annealing furnace The technical field, in particular, relates to a furnace door structure of an annealing furnace. Background technique [0002] The purpose of the annealing process after rolling of stainless steel strips is to uniform the chemical composition and structure of the steel strip, refine the grains, and adjust the hardness. The annealing process is usually carried out in an annealing furnace. The steel strip is transported in the annealing furnace. At this time, the temperature in the annealing furnace can reach up to 1600 degrees Celsius. The steel strip is passed out from the annealing furnace, and the surface of the steel strip is also accompanied by a very high temperature. The furnace door provided on the existing annealing furnace for the steel strip to pass out is an arched door, which is affected by the temperature of the steel strip, so that the existing furnace door is easy to collapse...
