Problems solved by technology

Although this method can avoid damage to the stave, it still needs to open grouting holes on the furnace shell, and the hole positioning operation is also very cumbersome, which reduces the efficiency of grouting and lining

Embodiment Construction

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

[0016] Such as Figures 1 to 4 As shown, the blast furnace body structure in this embodiment includes a furnace shell 1, a stave and a furnace lining 3 from outside to inside, and the stave includes an outer stave 2.1 that is close to the furnace shell 1 and is connected to the furnace shell 1. The inner layer stave 2.2 adjacent to the furnace lining 3, the inside of the outer layer stave 2.1 and the inner layer stave 2.2 are respectively independently arranged with circulating cooling water pipes 4, 5, and the circulating cooling water pipes 4, 5 are installed on the corresponding layer of staves The inside is uniformly wound, and the two ends of the circulating cooling water pipes 4 and 5 are respectively connected externally to the water inlet pipes 7.1 and 7.2 and the water outlet pipes 6.1 and 6.2.

[0017] The above water outlet pipes 6...

Abstract

The invention relates to a blast furnace body structure for facilitating lining making through grouting. The blast furnace body structure comprises a furnace housing, a cooling wall and a furnace lining from outside to inside in sequence, wherein the cooling wall at least comprises an outer-layer cooling wall propped against the furnace housing and an inner-layer cooling wall propped against the furnace lining; circulated cooling water pipes are independently arranged in the outer-layer cooling wall and the inner-layer cooling wall; the two ends of each circulated cooling water pipe are externally connected with a water inlet pipe and a water outlet pipe respectively; a ball valve is arranged at the water outlet of each water outlet pipe; a water lock is formed on each water outlet pipe. According to the blast furnace body structure, judging the cooling wall layer damaged by fire can be realized by detecting the water leakage condition correspondingly; through grouting slurry in the circulated cooling water pipe at the outermost layer of the cooling wall that water leakage exists, the slurry can overflow from the damage part of the circulated cooling water pipe to reach an eroded position of the furnace lining to realizing lining making, so that troubles that in the conventional lining making through grouting, the positioning and formation of a slurry pressing hole in a furnace housing are required before lining making are avoided, the operation of blast furnace lining making through grouting is simplified, and meanwhile, the accuracy and reliability of a grouting position are ensured.

Description

technical field [0001] The invention relates to a furnace body structure of a blast furnace which is convenient for later press-in grouting and lining. Background technique [0002] The cooling stave is a key component of the blast furnace body and a cooling device for the lining of the blast furnace. It cools the furnace body through circulating cooling water, which can effectively prevent the furnace shell from being heated and burned red, and is an important part to maintain the safe production of the blast furnace. Staves are installed on the shaft, waist, bosh, hearth and other parts of the blast furnace. They not only have to withstand high temperature and high pressure, but also bear the wear of the charge, the erosion of slag and the impact of the gas flow. Rapid cooling and rapid heating performance requirements are very high. After a period of production, due to factors such as construction quality and production operation, the cooling wall is easily damaged, and ...
