Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with specific embodiments and drawings.
[0017] The converter vaporization cooling flue, such as figure 1 , figure 2 , image 3 As shown, it includes a movable fume hood 1 located above the furnace mouth of the converter. The upper part of the movable fume hood 1 is connected with the lower part of the flue 2 of the fixed section of the furnace mouth. The connecting device 6 is connected, and the sealed telescopic connecting device 6 can be a telescopic joint. The upper part of the middle section flue 3 is connected to the end flue 4. There is an installation gap between the furnace mouth fixed section flue 2 and the middle section flue 3. An annular water tank 5 is provided in the installation gap. In practical applications, the annular water tank 5 can be fixed with a flange on the furnace mouth fixed section flue 2 or the middle section flue 3 through a bracket, and a water inlet pipe is pr...

Abstract
The invention discloses an evaporative cooling flue of a converter. The evaporative cooling flue comprises a movable smoke hood, wherein the movable smoke hood is positioned above the mouth of the converter, the upper part of the movable smoke hood is connected with the lower part of a furnace mouth fixed section flue, the upper part of the furnace mouth fixed section flue is connected with the lower part of an intermediate section flue through a sealing telescopic connecting device, and the upper part of the intermediate section flue is connected with a tail end flue; an installation gap is positioned between the furnace mouth fixed section flue and the intermediate section flue, the installation gap is internally provided with an annular water tank, and the annular water tank is provided with a water inlet pipe and a water outlet pipe. The evaporative cooling flue of the converter, which is disclosed by the invention, is internally provided with the annular water tank capable of shielding the installation gap positioned between the furnace mouth fixed section flue and the intermediate section flue, and therefore, hot red slag is difficult to scorify by entering a cavity formed by encircling the furnace mouth fixed section flue, the intermediate section flue and the sealing telescopic connecting device.
Description
Technical field [0001] The invention relates to a steel-making converter vaporization cooling flue for collecting and cooling high-temperature flue gas. Background technique [0002] The converter vaporization cooling flue is one of the main supporting equipment for the converter steelmaking. The equipment should maximize the collection and cooling of the high-temperature flue gas emerging from the furnace mouth during operation. [0003] The structure of the conventional converter vaporization cooling flue includes: a movable fume hood above the furnace mouth of the converter, the upper part of the movable fume hood is connected with the lower part of the flue in the fixed section of the furnace mouth, and the upper part of the flue in the fixed section of the furnace mouth is sealed with the lower part of the flue in the middle section. The telescopic connecting device is connected, and the upper part of the middle section of the flue is connected to the end flue; in order to com...
