Abstract

The invention discloses a process for filling a gap between a coke oven door frame and a protective plate, which comprises the following steps: S1-1, gap cleaning: firstly, after the coke oven door frame and the protective plate are mounted, cleaning the opposite sides of the coke oven door frame and the protective plate by using a cleaning brush, and then treating the cleaned dust by using a dust collector; the invention relates to the technical field of coke ovens. According to the technology for filling the gap between the coke oven door frame and the protection plate, materials are uniformly mixed, the surfaces of asbestos ropes and refractory fibers are all covered with slurry, then cotton ropes and refractory fibers are placed into the gap between the coke oven door frame and the protection plate, and then grouting operation is conducted on the gap between the coke oven door frame and the protection plate. According to the present invention, the filling operation is more convenient, and the characteristics of the filling material are improved so as to effectively improve the heat resistance and the shock resistance of the coke oven, such that the service life of the product is prolonged.

Description

technical field [0001] The invention relates to the technical field of coke ovens, in particular to a process for filling gaps between a coke oven oven door frame and a protection plate. Background technique [0002] Referring to the Chinese patent, the patent name is: a method for filling the gap between a coke oven door frame and a protective plate (patent publication number: CN202011039194.8, patent publication date: 2022.02.08), which includes cleaning the coke oven door frame and protecting the The gap between the plates; the ceramic fiber rope is filled in the gap in the order from bottom to top; the concentrate powder is filled between the ceramic fiber rope and the gap under the negative pressure of the carbonization chamber; the exposed surface of the gap in the ceramic fiber rope One side is coated with water glass. In the invention, the gap formed by the furnace door frame and the protective plate is filled with concentrate powder, ceramic fiber rope and water gl...
