Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] A method for repairing the water cooling system of a blast furnace stave. The cooling system includes a cooling water pipe 8 and an external water pipe 3. The cooling water pipe 8 communicates with the external water pipe 3. The cooling water pipe 8 passes through the furnace shell 1 and the packing layer 2 and is embedded in the blast furnace stave 5. middle.

[0017] When the cooling water pipe 8 is damaged and leaks in the stave 5 of the blast furnace, as figure 1 As shown, first disconnect the cooling water pipe 8 from the external water pipe 3 outside the furnace shell 1, then insert the metal hose 6 into the broken and leaking cooling water pipe 8, and then disconnect the two ends of the metal hose 6 from the The external water pipe 3 is connected; the metal hose 6 located outside the furnace shell 1 is provided with a valve 4 for control, and the groutin...

Abstract

The present invention relates to a method for preparing water cooling system of blast furnace cooling wall. A technical scheme is that: the cooling system includes a cooling water pipe (8) and an outer water pipe (3), the cooling water pipe (8) communicates with the outer water pipe (3), the cooling water pipe (8) is beset on the blast furnace cooling wall (5) passing through a furnace shell (1) and a filling agent layer (2). When the cooling water pipe (8) is broke and water leakage in the blast furnace cooling wall (5), the cooling water pipe (8) disconnects with the outer water pipe (3) on the furnace shell (1), then a metal flexible pipe (6) passes through the cooling water pipe (8), and two ends of the metal flexible pipe (6) communicates with the disconnected out water pipe (3). The metal flexible pipe (6) located on the furnace shell outside is equipped with a valve for controlling, grouting material (7) is filled between the metal flexible pipe (6) and the furnace shell (1). The method has characteristics of convenient operation, safety, low cost and superior integrality which can be widely used for preparing the water pipe with water leakage in the blast furnace cooling wall system.

Description

technical field [0001] The invention belongs to the technical field of blast furnace staves. In particular, the invention relates to a method for repairing a blast furnace stave water cooling system. Background technique [0002] In recent years, with the continuous improvement of blast furnace smelting intensity, the pace of production is getting faster and faster, various production indicators are getting higher and higher, and the equipment requirements for the blast furnace body are correspondingly higher and higher. Especially in the middle and late stages of the furnace operation, the furnace lining on the upper part of the furnace will fall off in a large area, the cooling wall will be frequently damaged, a large amount of water leakage in the furnace, the furnace body will become cold, even the tuyere will be filled with slag, and the furnace hearth will freeze. Blast furnace production. Therefore, it is necessary to analyze the cause of stave damage and find an ef...
