Zusammenfassung:	A coil-type heating structure comprises a plurality of coil-type heating elements spaced apart and arranged axially, and a plurality of positioning members. The plurality of the coil-type heating elements are respectively mounted and positioned on inner walls of a surrounding insulation body in a vertical heating furnace by the plurality of the positioning members. Each coil-type heating element is sheet-shaped and is formed in a serpentine shape by way of having a plurality of peaks and troughs alternately connected to each other. Each coil-type heating element has a wave-shaped cross section, and has at least one peak portion and at least one trough portion alternately connected to each other, so as to increase the ability of the coil-type heating elements to resist deformation caused by high temperature, and thus to prolong its service life.
