W type radiant tube by Qingdao Hexin Machinery Co.,Ltd.
W type radiant tube W type radiant tube used for continuous annealing furnace, continuous galvanizing line vertical annealing furnace, W-type radiation is no indirect oxidation heating element, under the protection of the atmosphere of nitrogen and hydrogen, let the heat through the tube wall radiation to the workpiece, the radiative heat transfer through the outer tube, annealing treatment was carried out on the workpiece. W-type radiant tube The W-type radiant tube are usually used for continuous annealing line and galvanizing line vertical annealing furnace,Under the hydrogen nitrogen protective environment, and in order to avoid fuel combustion products contact with the workpiece, allows the fuel combustion procedure to carry out in the radiant tube, Tube is provided by natural gas or coke oven gas combustion heat energy,and radiate the heat to workpiece through tube wall,By way of radiation heat transfer outside tube,and make the strip steel running at a consta...
