Abstract

The invention provides a furnace mouth structure of an annealing furnace. The furnace mouth structure comprises a fireproof baffle arranged at the front end of a furnace mouth, and the fireproof baffle is liftably fixed to a bracket nearby the furnace mouth. With adoption of the technical scheme, the furnace mouth of the annealing furnace can be covered with the fireproof baffle, along with the different lifting and dropping positions of the fireproof baffle, the furnace mouth sealing degree of the baffle is different, and the influence on the temperature in the furnace is different, so that the influence in the temperature can be controlled very well.

Description

technical field [0001] The invention belongs to the field of strip steel processing equipment, and in particular relates to a furnace mouth structure of an annealing furnace. Background technique [0002] In the process of strip steel production, annealing treatment is required. The existing annealing furnace mouth is relatively large, so the temperature in the annealing furnace will not be well controlled. How to design a heat preservation device for the annealing furnace mouth has become a basic Topics studied by technical personnel in the field. Contents of the invention [0003] In view of this, the present invention aims to provide a furnace mouth structure of the annealing furnace to solve the problem that the temperature in the annealing furnace is difficult to control. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] A furnace mouth structure of an annealing furnace, comprising a bracket ...
