Abstract
PURPOSE: To reduce a production cost by forming a hollow blank pipe from a solid blank material through a punching press, then, inserting a mandrel to the blank pipe and forging.
CONSTITUTION: The hollow blank pipe is formed from the solid blank material by utilizing the punching press, then to deal with a generated thickness eccentricity, a rolling with a small rolling reduction or a blank rolling without a plug is performed to correct the thickness eccentricity. Furthermore, a mandrel is inserted in the hollow part of the hollow blank pipe to product a seamless steel pipe by forging. Moreover, the steel pipe is left as it is or cold worked by a pilger mill to obtain the product with a required dimension. In this way, because the product is obtained from a hardly workable material by utilizing a part of existing equipments efficiently, the production cost is largely reduced.
