Study on a Nozzle for Improving Atomization Effect of Spray Gun and Increasing Specific Surface Area of Iron Oxide Powder
The cold rolling acid regeneration unit is responsible for treating the waste acid from the pickling line and supplying the regenerated acid.The waste acid is processed through the desilication system,the calciner system and other process links to produce the regenerated hydrochloric acid for the pickling line.At the same time,the by-product of high added value is iron red,which generally refers to iron oxide.Iron oxide is an inorganic compound with chemical formula of Fe2O3,which is a red-brown powder.Iron oxide is used as soft magnetic ferrite material,with high chemical purity,fine and uniform particles,spherical layout,SBET(specific surface area),usually 3.0 m2/g.The specific surface area is also an important physical and chemical indicator to measure iron red.This paper studies the specific surface area of iron red,and studies a method that can improve the atomization effect of spray gun.The nozzle can improve the specific surface area of iron red.
