Beam.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of palletizing shaft furnace air-guiding wall water beams,
The shaft furnace includes the burner hearth being made up of furnace wall, has a pelletizing charging aperture in the upper end of burner hearth, has one in the lower end of burner hearth
It is provided with air feed mouthful, the air feed mouthful in air-guiding wall, the air-guiding wall and is provided with water cooling tube group, its innovative point is：
The water cooling tube group one has two groups, is symmetricly set on the two ends of air-guiding wall, and along the long axis direction of air-guiding wall
Extension, every group of water cooling tube group by it is some from top to bottom successively and the water cooling tube of column distribution is collectively formed；
Alloy lining group is welded with the inwall of every group of water cooling tube group, the alloy lining group is by some along water cooling
The liner plate of pipe range direction of principal axis and column distribution is collectively formed, and intersects expansion joint, the liner plate using inclined-plane between adjacent liner plate
Overall is in inverted l shape, is perpendicular in side of the liner plate away from water cooling tube, the side welded in liner plate with water cooling tube is provided with
The arc groove fitted with water cooling tube, the upper end of the liner plate hangs in water cooling tube group the upper of the water cooling tube for being located at top
Side, and the upper surface of liner plate is horizontal plane.
Further, the trapezoidal shape of weld seam between the water cooling tube and liner plate.
The utility model has the advantage of：In the utility model, served as a contrast by setting up alloy on the inwall of water cooling tube group
Plate, so as to will be changed into plane on the inside of water cooling tube, eliminates the whirlpool including pelletizing and reduces erosive wear, effective to extend water
The service life of cold pipe, has reached more than 18 months.
For the setting of liner plate, the design at expansion joint is intersected using inclined-plane, so as to avoid the shadow because of hot environment
Ring and cause liner plate to produce crack or destruction, it is ensured that the stability of lining plate structure, upper end integral planar ensure that liner plate is hung
Stability and air-guiding wall install flatness.
When being welded to water cooling tube and liner plate by the way of trapezoidal weld seam, so as to increase weld seam and water cooling tube
Contact area, allows weld seam to obtain water-cooled effect with water cooling tube fully contact, it is ensured that the Weld Performance under high temperature so that liner plate will not
Come off.
