centrifugal cast radiant tubes by Qingdao Hexin Machinery Co.,Ltd.
centrifugal cast radiant tubes The straight pipe of W type radiant tube adopts centrifugal casting, the molten stell was casted into a variety of tube blank under the action of centrifugal force , after the boring machine boring hole, the lathe machining welding groove, bend adopts precision casting technology, qualified after the examination, to assembly and weld according to the drawing . 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 constant speed heate...
