Abstract
The utility model relates to a W-shaped pitting surface radiant tube which belongs to the heat supply element of the indirect heating of non-oxidation. The utility model is mainly used for the continuous annealing machine set of the bright annealing of the band steel. The utility model is composed of a straight tube and a bending tube, and the connecting part of the straight tube and the bending tube is welded. The outer surface of the straight tube is studded with a pit-shaped convex thorns, so the area of the heat radiation of the outer surface of the straight tube is increased, and the efficiency of the heat transfer is improved. The whole radiant tube is a W shape, and the inlet and the outlet of the whole radiant tube is positioned at the same side of the whole radiant tube; so the heat loss can be reduced when the utility model is disassembled or changed, and the expansion influence of the line of the utility model can not cause the difficulty of the assembly and the disassembly.
Description
The utility model relates to a kind of W type pitted skin radiator tube, belongs to the heating element of non-oxidation indirect heating, is mainly used in the continuous annealing unit of band steel clean annealing, also is applicable to the process furnace or the annealing furnace of protective atmosphere.
The radiator tube that generally uses all is the straight type radiator tube of light face at present.This radiator tube requires the furnace wall that two relative perforation are arranged owing to be straight type during installation, will cause bigger calorific loss when changeing.Simultaneously, because the cause of thermal expansion, when temperature rose to 1000 ℃, the pipe under the normal temperature will extend 15 millimeters for every meter.This just causes the difficulty of installation, dismounting, also easy damage equipment.In addition, this radiator tube is owing to be the light face, and the surface radiating area is little, and heat conduction efficiency is low.
The purpose of this utility model is to overcome the weak point of existing radiator tube, provides a kind of not because of thermal expansion is affected, easy installation and removal, and the surface radiating area is big, the W type pitted skin radiator tube that heat conduction efficiency is high.
The utility model is achieved in that W type pitted skin radiator tube is made of straight tube and bend pipe, and the straight tube outside surface is covered with the protruding thorn of pit shape.The alternate setting of straight tube and bend pipe, the junction of straight tube and bend pipe welds together, and argon arc welding bottoming, welding process or other welding process that electric-arc welding is filled are adopted in its welding.The W type that integral radiation Guan Chengsan road is curved or five roads are curved, its import and outlet are positioned at the same side of body.The protruding thorn of pit shape on the straight tube outside surface adopts rotational casting and makes in the method for die sleeve internal surface spraying special coating.
This W type pitted skin radiator tube is because body is the W type, and import and export is positioned at the same side, only in the same side of furnace wall perforate, reduces calorific loss when changeing during installation, also can not cause the difficulty of loading and unloading because of the influence of body polar expansion.The straight tube outside surface is covered with the protruding thorn of pit shape, increases area of dissipation more than 30% than smooth pipe, improves heat conduction efficiency greatly.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
W type pitted skin radiator tube is made of straight tube 1 and bend pipe 2, the alternate setting of straight tube and bend pipe, and the argon arc welding bottoming is adopted in its junction, and the welding process that electric-arc welding is filled welds together.The outside surface of straight tube is covered with the protruding thorn 3 of pit shape, is to adopt rotational casting and make in the method for die sleeve internal surface spraying special coating.The W type that integral radiation Guan Chengsan road is curved, its import 4 and outlet 5 are positioned at the same side of body.This radiator tube tube outer diameter is 168 millimeters of φ, and internal diameter is 152 millimeters of φ, and whole long 2244 millimeters, the straight tube width between centers that is arranged in parallel is 300 millimeters.
