Abstract

PURPOSE:To increase the high-temperature strength and cooling efficiency of a boom even having a long length and to enable the mending in hot state over a long period by connecting water-cooled pipes with a pair of steel sheets lined with a heat-insulation material and using a boom in the cooled zone formed by the above components. CONSTITUTION:An upper and a lower water-cooled pipes 1 placed interposing a prescribed gap are connected through a pair of steel plates 10 lined with a heat-insulation material 13 to form a zone cooled with air. A boom provided with a main pipe containing a feeding pipe for oven-mending material and a camera cable, etc., is placed in the cooled zone to obtain the objective melt- spray mending apparatus for coke oven.

However, since coal carbonization is indirect heating through the side walls of brickwork, long-term use may cause coke to fuse with the bricks, collapse of the brickwork side walls, or damage the side walls when taken out of the kiln. Therefore, the life of a normal reactor is said to be about 20 years.

(Function) The feature of the thermal spray repair apparatus for a coke oven carbonization chamber of the present invention is that two water-cooled pipes are arranged vertically at a predetermined interval, and the space between them is connected by two steel plates coated with a heat insulating material. A cooling area is formed by air, and in this space, the furnace repair materials (refractory powder for thermal spraying, propane gas, oxygen, cooling water for the tip),
This is because a main pipe is provided to accommodate cables for surveillance cameras, etc., and the predetermined interval refers to the volume that accommodates this main pipe.

The structure has water-cooled pipes on the top and bottom, and the cross section is long in the vertical direction. This allows for sufficient cooling to the tip of the long boom, which can accommodate narrow spaces in the middle, and also ensures the necessary rigidity to support the weight of the main pipe. In addition, when forming a double tube with a cross section close to a right circle like a normal water cooling jacket,
This is to avoid the shortening of the distance to the side wall and the increased exposure to radiant heat from the side wall of the kiln.
