Product Description

Supply top alloy centrifugal casting radiant tube and eblow 180degree

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.
