The invention discloses a composite heating type heat treatment furnace. The composite heating type heat treatment furnace comprises an induction coil arranged on the outer side of a furnace body andused for sensing a heated material and an electrode pair arranged in the furnace body as a secondary heating element, and the induction coil arranged at the outermost layer of a graphitizing furnace is used as a furnace shell. According to the composite heating type heat treatment furnace, by combining induction heating and electrode pair direct current heating, the heating effect is obviously improved, and meanwhile, the uniformity degree of material heating is improved.
