Description

TECHNICAL FIELD

[0001] The utility model relates to converter swing furnace room auxiliary equipment technical field, especially a converter swing furnace room observation window. BACKGROUND

[0002] In the converter steelmaking process, converter swing furnace workers need to observe the running condition of the furnace body tilting and the ladle car through the observation window of the converter tapping swing furnace room, so as to complete the tapping operation on the operation platform.

[0003] The conventional swing furnace room observation window design is to open an observation hole of 400mm*400mm at a place 1.0-1.2m away from the ground, and to design a steel door that can be pushed and pulled or rotated. The main function of the steel door is to be closed during the blowing process to prevent the steel slag in the blowing process from falling into the swing furnace room and damaging the equipment. When tapping, the swing furnace worker opens the steel door and observes the converter tapping process through the observation window to determine the position change of the furnace body tilting and the ladle car with the help of the observation window.

[0004] During the tapping process, the molten steel reacts with slag, alloy material, carbon powder, etc. after entering the ladle, and a large amount of smoke is generated under the action of strong stirring at the bottom of the ladle. High-temperature smoke will drift into the swing furnace room through the observation window. In addition, the converter gun cleaning operation and the slag falling off the flue will also fall into the swing furnace room. High-temperature smoke and slag pose a threat to the working environment and safety of swing furnace workers. In order to suppress the influence of high-temperature smoke on the observation of swing furnace workers during tapping operation and prevent foreign matter from entering the eyes, an axial flow fan needs to be set up for forced blowing. In winter, the use of the axial flow fan is very cold for the swing furnace workers. INVENTION CONTENTS

[0005] In view of the problem that high-temperature smoke will drift into the swing furnace room through the observation window, the utility model provides a converter swing furnace room observation window.

[0006] To solve the above problems, the utility model adopts the technical scheme that,

In use, compressed air is introduced into the airtight frame through the air inlet pipe, and then discharged through the air outlet pipe, thereby reducing the passage of high-temperature flue gas.

[0010] Preferably, the shell is integrally arranged as a regular quadrangular prism shell; and the larger opening end of the shell is fixedly arranged on the first guide rail.

[0011] Preferably, the plane in which the inner side wall of the airtight frame is arranged forms an acute angle with the center line of the window; and the center line of the air outlet pipe is perpendicular to the inner side wall of the airtight frame. The air outlet pipe can be directed towards the window, so that the gas discharged from the air outlet pipe collides with the high-temperature flue gas, thereby reducing the entry of high-temperature flue gas.

[0012] Preferably, the second guide rail is fixedly arranged on the upper and lower sides of the end of the smaller opening end of the shell; the glass frame is slidably arranged on the second guide rail; and a plurality of supporting rods are fixedly arranged between the second guide rail and the first guide rail, thereby ensuring the stability of the glass window frame and the stability of the sliding of the glass window frame.
