Abstract

The invention discloses a repair method for rush repair on a hot-blast stove burner. The repair method comprises the following steps: clearing a breakdown old wall body region of a gas passage protection wall; laying a new wall body in the cleared breakdown region, wherein the new wall body and an old wall body which is not cleared are located in a same plane, but a gap is reserved between the new wall body and the old wall body which is not cleared; and pouring self-flow castable between the new wall body and the old wall body which is not cleared. The repair method for the rush repair on the hot-blast stove burner, disclosed by the invention, is capable of rapidly repairing the gas passage protection wall in a short time, and airtightness of the gas passage protection wall of the hot-blast stove burner is ensured to meet requirements of an original design.

Description

technical field [0001] The invention relates to the technical field of hot blast stove burners, in particular to a repair method for the emergency repair of hot blast stove burners. Background technique [0002] The burner is set at the lower part of the combustion chamber of the hot blast stove. The burner is a key part of the blast furnace hot blast stove. It includes a gas channel protection wall. The gas channel protection wall is a rectangular cylindrical brick wall, and the gas flows from the gas channel protection wall. The inner cavity of the gas channel passes through, and the outside of the gas channel protective wall is connected with a permanent layer of castable material in the shape of a rectangular tube. The key to the masonry of the gas channel protection wall is that it cannot produce cross gas with the air channel. The air channel is located outside the permanent castable layer. Once the gas channel protective wall fails and the gas passes through the brick...
