Abstract

PURPOSE:To make the saving of fuel gas and reduction of required heating time possible by flowing the high temp. frames of plural burner elements disposed by leaving suitable intervals in the longitudinal direction of the heating furnace of objects to be heated in contact with the heating furnace from oblique directions. CONSTITUTION:For example, plural burner elements 1 are disposed by leaving suitable intervals around the intended circumferentially welding part (a) of metallic pipes. A, A supported freely rotatably around the pipe axial center by means of a pair of turning rollers 2, 2, etc. While the high temp. gaseous frames (f) ejected from these elements 1 are flowed toward the tangential direction in contact there- with in such a way that continuous or approximately continuous or intermittent frames are formed around the intended place (a), whereby the intended place (a) is locally heated. After this preheating, the pipes A, A are rotated and are circumferentially welded. Further, if necessary, the pipes are subjected to postheating for the purpose of stress relieving or the like in the same manner as the above-mentioned preheating.
