用局部加熱炉。 A horizontal forging machine installed in an upsetting forging line has a furnace body installed in the heating chamber so that the heated section of the steel pipe that penetrates the heating chamber is placed in the heating chamber for rapid local heating, and the boundary of the non-heated section is locally cooled. A local heating furnace for upsetting forging of steel pipes is provided between an upsetting die and an upsetting punch of a press machine so as to be freely engageable with a column of the forging press machine.
