Title:
MANUFACTURE OF SEAMLESS TUBE
Document Type and Number:
Japanese Patent JPH0313223
Kind Code:
A
Abstract:
PURPOSE: To execute the manufacture with high efficiency by specifying the drawing quantity of a tube and a plug mill entry side surface temperature, at the time of manufacturing a Ti or Ti alloy seamless tube.
CONSTITUTION: At the time of manufacturing a Ti or Ti alloy seamless tube by a two roll skew rolling method, rolling is executed by setting (i) wall thickness reduction, and (ii) a tube surface temperature of an entry to 0.5-2.0mm and 600-1150°C, respectively, in a plug mill, by which the seamless tube can be manufactured with high efficiency, and also, economically.
