U-type radiant tube by Qingdao Hexin Machinery Co.,Ltd.

 U-type radiant tube:

 The U-type radiant tube are usually used for continuous annealing line and galvanizing line vertical annealing furnace, under the hydrogen nitrogen protective environment, 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 heated to 900quickly from the normal temperature, and make annealing treatment to strip steel.straight pipe adopt centrifugal casting as casting, precision casting for the elbow,the material is high nickel chromium alloy cast steel, such as 2.4879,1.4852,ZG45Ni48Cr28W5Si2、MORE1、MORE2.

These can be with or without flanges, bellows, collars, and/or insulation already installed.

centrifugal casting radiant tube

straight pipe of U-type radiant tube is made of high temperature resistant centrifugal casting pits pipe, bend adopts precision casting technology, U-type radiant tube used for even back, galvanizing line horizontal annealing furnace and silicon steel heat treatment furnace, under the protective atmosphere of nitrogen and hydrogen, radiant tube by natural gas or coke oven gas combustion heat energy, through the outside of the tube radiation radiation heat transfer, uniform operation of the strip from room temperature quickly and evenly heated to about 900 degrees, the strip annealing.
