Embodiment Construction

[0015] Further illustrate the present invention below in conjunction with embodiment and accompanying drawing.

[0016] Such as figure 1 , 2 In the illustrated embodiment, the illustrated top-blown oxygen lance is composed of a modified Laval nozzle 1 and a gun body 2 butt welded. The nozzle 1 is provided with five nozzles 1-1, and an annular oxygen supply channel is arranged around each nozzle. The annular oxygen supply The channel communicates with the main oxygen channel 5 in the gun body 2 . The gun body 2 and the nozzle 1 of the top-blown oxygen lance are provided with a through hole 3 inserted into the camera body 4, and the through hole 3 is connected with the oxygen lance annular water-cooling pipeline 6 .

[0017] The end hole located at the rear end of the gun body through the tunnel is connected with a pipeline 7, and the pipeline 7 is provided with a three-way joint 8, one of which is connected to the cold air input pipeline 9, and the other interface is connect...

Abstract

The invention discloses a photographic device inside an attachment-type refining furnace, which comprises a photographic device body and is characterized in that through pore paths imbedded with the photographic device body are arranged on the body and on a spray head of a top blowing oxygen gun; the end holes of the through pore paths at the rear end of the gun body are connected with video signal output cables and pipelines of power supply cables which input cold air and lead out the photographic device body; the end holes of the through pore paths on the surface of the spray head are towards a molten pool of the refining furnace and provided with supporting convex plates of the photographic device body; the front end edge of the photographic device body are distributed with air passinggrooves. In the device, the photographic device body with small size and the top blowing oxygen gun with available space which lead the body to attach the top blowing oxygen gun are utilized, and thedevice has the advantages that the structure can be simplified and the defects that the molten pool is observed sidewise by using a exploration-in-type photographic device in the furnace are overcomeby a more perfect cooling system, thus the condition of smelting in the furnace can be accurately reflected by displaying of the image and molten steel outlet of the refining furnace and the working state of the steel ladle can be observed.

Description

technical field [0001] The invention belongs to a camera device, in particular to a camera device in an attached refining furnace. Background technique [0002] The camera device in the refining furnace is an important equipment for observing the smelting status in the furnace. The basic structure is composed of a protective cover, an imaging lens at the front end of the protective cover, a camera for converting optical images into image electrical signals, and a video signal output cable. and power cables. [0003] In order to overcome the defect that the in-furnace camera device cannot be placed in the furnace for a long time, a camera device with a water-cooled or air-cooled composite sleeve outside the protective cover came into being. However, the camera device provided with the cooling composite jacket makes its structure more complicated, and the production and use costs are obviously increased. In addition, the above-mentioned camera device with cooling composite j...
