In or immediately choose seamless elbow through anticorrosive cleaning, this use time will be greatly increased. Second, in the period of cleaning the seamless elbow is also to produce the surface defects, any product in the production period is sure to appear a little flaw

In order to effectively ensure the use of the period of trouble, we must pay attention to the standard of this section, this will not affect the normal effect, so to clean up these defects, so there will be no defects.

The fuel selection is not reasonable, when the billet is placed into the furnace for heating, it needs to be put into the fuel.
