Abstract
PURPOSE: To prevent the surface roughening in the inner surface of the seamless steel pipe, by blowing air, water, etc., against inner surface of the hollow cylindrical body before being subjected to the rolling pass to be performed by the elongator mill, in order to blow off the scale from the inner surface.
CONSTITUTION: The fact, that the surface roughening of the product, that is the seamless steel pipe, is caused by the scale, is ascertained; after forming the hollow cylindrical body from the steel billet by the piercing mill, and before being subjected to the rolling work by the elongator mill, the fluid like as air, water, etc., is blown against the inner surface of the concerned hollow cylindrical body, and the scale is blown off and removed from the inner surface. This method can be effectively applied to the elongator mill (elongator mill) included in the rolling process.
