1. A styrene heating furnace comprising a radiant section having a heat exchange tube (10), characterized in that the heat exchange tube comprises a twisted sheet tube section, the heat exchange tube (10) is provided therein with a heat transfer enhancement element comprising a first heat transfer enhancement element provided inside the twisted sheet tube section, the first heat transfer enhancement element is a first twisted sheet (1), the first twisted sheet (1) is a trace curved surface through which a line segment in a horizontal direction rotates about its own midpoint while also translating upward or downward in a vertical direction of the heat exchange tube (10), and in a cross section of a portion of the tube section of the heat exchange tube (10) provided with the first twisted sheet, a cross section of the first twisted sheet is always an inner diameter of a cross-sectional circle of the heat exchange tube (10), wherein the first twisted sheet (1) comprises a pair of upper and lower side edges which are parallel to each other, and a pair of twisted sides having an upper side and a lower side equal to the diameter of the heat exchange tube (10), both of the twisted sides being in contact with the inner wall of the heat exchange tube (10) at all times, the first twisted piece (1) having a vertical hole formed therethrough from the upper side to the lower side of the first twisted piece (1) in the axial direction of the heat exchange tube (10) to divide the first twisted piece (1) into two twisted portions, wherein the heat exchange tube has a diameter D.
