Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical industry, in particular to a walking type heating furnace water beam. Background Art

[0002] In the metallurgical industry, there is an iron ditch just below the blast furnace tuyere platform of metallurgical equipment. Liquid metal at 1500℃ flows along the iron ditch from the iron outlet of the blast furnace. The heat brought by the high-temperature liquid metal roasts the steel beams of the tuyere platform. Even if the bottom of the steel beams of the tuyere platform are insulated with spray coating, a large amount of heat is still transferred to the steel beams, and then transferred to the top of the tuyere platform, making the tuyere platform at a high temperature. First, the high temperature will cause the steel beams to fatigue quickly and damage the structure of the tuyere platform. Secondly, the high temperature of the tuyere platform is not conducive to production operations on the tuyere platform and is not conducive to production safety.

[0003] Based on the above defects, it is necessary to improve the heat dissipation structure at the tuyere platform and the steel beam of the blast furnace. The currently proposed means is to pass water inside the steel beam to directly cool the steel beam to take away the heat transferred to the steel beam, reduce its temperature, and also reduce the heat conducted to the top of the tuyere platform; however, this cooling method requires high structural tightness of the steel beam. If the steel beam is deformed by heat and causes local damage, it is easy to cause water leakage in the steel beam. When the water leaks onto the molten iron in the iron ditch, it will produce a large amount of steam after gasification at high temperature, which is easy to cause explosion, posing a safety hazard. Therefore, the practical effect is not good.

[0004] Application number: CN202122555047.2 discloses a water-cooled beam for a blast furnace tuyere platform, comprising a beam body, a water pipe and a refractory filler. The beam body is a hollow structure, the water pipe is placed inside the beam body, and the refractory filler is filled between the water pipe and the inner wall of the beam body. In the utility model, a cooling fluid is passed through the water pipe, and the gap between the water pipe and the inner wall of the beam body is filled with a refractory filler. The heat received by the beam body is transferred to the water pipe through the refractory filler, and then the heat is taken away by the cooling fluid flowing in the water pipe.

[0005] However, when the above device is used, the beam body is hollow, so that the beam body is easily deformed when subjected to force, and the water pipe is not supported, so that the longer water pipe is easily deformed. Therefore, it is necessary to propose a walking heating furnace water beam. Utility Model Content
