Description

technical field [0001] The invention belongs to the technical field of dredging of converter vaporization flue, and particularly relates to an automatic dredging system and a dredging method for sampling holes of converter vaporization flue. Background technique [0002] Oxygen converter steelmaking flue gas is one of the main air pollutants produced in the converter steelmaking industrial production process. The coal gas and iron-containing dust in the converter flue gas must be recovered and utilized. Since the converter steelmaking flue gas temperature is as high as 1600 degrees, so The first process after the converter flue gas is generated is to use the vaporization cooling flue to cool down, and at the same time, to recover the steam generated by heat exchange. In order to make the gas recovery larger, and effectively and accurately control the fan speed of the system, devices such as pressure taking are often installed on the flue. Due to the high temperature of flue...
