Abstract

PURPOSE: To heat quickly the heteroprofile portion of a heating furnace by utilizing contact heat transmission, convection heat transmission, and radiation heat transmission in the heating of an object to be heated, having an expanded heteroprofile portion in the heating furnace.
CONSTITUTION: The pipe 18 to be heated, having the upset portion 17, is put into the heating furnace 1 by the quide roller 5, where the general pipe portion is placed on the skid 6 and moved in the furnace and also the upset portion 17 is placed on the auxiliary skid 7 and moved in the furnace for heating while the hot air 11 from the hot air generator is jetted upwardly from the upper slit 19 through the conduit 10, the plate tube 9, and then the pipe 8 inside the auxiliary skid 7 to heat the upset portion 17 by convection of the hot air. The upset portion 17 is heated also by contact heat transmission by the auxiliary skid 7 heated by the hot air passing by and at the same time heated quicky by even radiation heat transmission from the wall of the heating furnace body 1 and also by the high-temperature auxiliary skid 7. Thus, uniform heating can be performed without danger of partial heating because the pipe 18 is sent forward while being turned.
