Abstract

The invention relates to a repair tooling of a hot-blast branch pipe lining of a hot-blast furnace and a repair method thereof. The repair tooling comprises split type structural support track beams including a left support track beam and a right support track beam, wherein the support track beams are connected with end flanges of hot-blast branch pipes, two sliding trolleys are installed on the support track beams in a sliding mode, and insulation blind plates are respectively hoisted on each sliding trolley. The hot-blast branch pipe lining of the hot-blast furnace is repaired in a hot state of the hot-blast furnace by utilizing the repair tooling of the hot-blast branch pipe lining of the hot-blast furnace, and the repair method mainly comprises the following steps that after the blast furnace blows down, firstly, the hot-blast furnace is put in a cold stoking state, the condition that the states of all valves meet operation requirements on site is confirmed, the lining repair tooling is installed, an insulation wall is built, the lining is repaired, the repair tooling and the insulation wall are disassembled, and the hot-blast furnace is reassembled and started to normally supply air. According to the scheme, the lining of the hot-blast furnace cannot be influenced by low temperature, and the repair can be quickly realized; in an actual repair process, the safety of operating personnel is guaranteed, and the repair difficulty is reduced; additionally, a hot-blast valve is installed with time saving and labor saving, and the operating efficiency is greatly improved.

Description

technical field

[0001] The invention belongs to the technical field of repairing in the actual production of a hot blast stove, and in particular relates to a tool for repairing the inner lining of a hot blast branch pipe of a hot blast stove and a repair method thereof. Background technique

[0002] As we all know, the hot blast stove works for a long time, and the refractory materials in the heat-sealed branch pipes on both sides of the hot blast stove will age and fall off. Once they fall off, it will seriously affect the hot blast branch pipes, especially the hot blast valve; Stop running, and when the temperature drops to a certain temperature, the operator wears heat-insulating clothing for repairs, but once the hot blast stove is at low temperature, the refractory material on the inner wall of the hot blast stove will loosen and fall off in a large area; comprehensively considering that the hot blast stove cannot be stopped It must be repaired at a temperature not low...
