Problems solved by technology

Limited by the technical level and conditions at that time, the camera was large and expensive. The camera was installed outside the furnace shell, the observation hole was large, the moving and protective devices were complicated, the life of the scanning device was short, the amount of protective gas was large, and the production high maintenance costs
During the use of the blast furnace, the problem of ash on the camera lens and window has not been solved. The complicated window valve and mechanical focusing device often break down. Maintenance and repair cannot be carried out during the production process of the blast furnace, and they can only be dealt with when the wind is off , so it has not been promoted

Embodiment Construction

[0009] Holes are drilled at appropriate parts of the top furnace shell of the blast furnace 1, and the flange short pipe 4 is welded. The tubular cooler 9 is inserted into the furnace through the gasket 5 and the flanged short tube 4, and the cooler is installed and tightened with bolts 6, washers 7 and nuts 8 to ensure tightness. Water is supplied to the tube cooler 9 from the valve 10, and the water is discharged from the drain port 11 to ensure the cooling effect. Pass the protective gas (nitrogen or clean gas) into the blast furnace from the valve 12, and continuously purge the peep hole 21 through the purge ring gap 28 between the purge ring 22 and the camera 19. Special camera 19 and temperature measuring element 20 are installed at the front end of camera gun 16, inserted into cooler front end by sealing sleeve 15, connecting pipe 14 and valve 13, and protective gas (nitrogen or clean coal gas) passes in the camera barrel from valve 17 , Blow into the furnace from the ...

Abstract

The invention provides an image process method for image generated by plug-type camera in stove, especially monitors the work state of fuel in the stove in process of puddling high furnace, and uses computer to process the image in order to describe the air and temperature distribution state of fuel, monitor the work state of chute and big clock and the material flow state, and monitor the abnormal state of tube and material collapsing in stove. The camera is made up of the body, camera, monitor, digital thermometer, computer and color monitor. The advantages lie in: it uses micro-camera without moving part to acquire the infrared image in stove, and uses the computer to process the image.

Description

technical field [0001] The invention belongs to the technical field of process monitoring and control of industrial furnaces, and in particular provides an image processing method for images of plug-in furnace cameras. It is a divisional trial of 02121548.0 "A plug-in kiln camera and image processing method" based on the examiner's opinion. Background technique [0002] In the early 1990s, domestic and foreign researched and developed the "Blast Furnace Roof Temperature Camera" (invention patent, patent No. 90102986) and "monitoring camera" (invention patent, patent No. 94115659). There is also a The thermal imager adopts the mechanical scanning method to obtain the image of the temperature distribution of the material surface, which is used to observe the condition of the material surface and analyze the temperature distribution of the material surface, and is used to guide the operation of the blast furnace, which is a big step forward for opening the black box of the blas...
