The invention provides a conveying method of a
heating furnace of a continuous glass
toughening furnace, and belongs to the field of glass
toughening. According to the method, a
heating furnace conveying line is divided into a normal-speed section, an acceleration section and a rapid section, wherein in the normal-speed section, the glass is driven to be conveyed at a
constant speed at the speed of V flat; in the rapid section the glass is driven to be conveyed at a
constant speed at the speed of V<rapid>, V<rapid> being larger than V<normal>; and in acceleration section, variable-speed conveying of the glass is controlled, and the glass is limited at the temperature required by heating to
tempering in the rapid section. According to the invention, the accelerating section on the conveyingline of the existing
heating furnace is advanced, and meanwhile, the quick section is added behind the accelerating section, so that the glass is limited at the temperature required by the quick section to be heated to be tempered, i.e., the glass is completely heated in the quick moving process and moves in a quick passing manner before being heated to a
softening point; as a result, the deformation amplitude of the glass is effectively reduced, so that the defect that raised grains are likely to appear on the surface of the glass is overcome, the effect is more obvious especially for ultrathin glass with the glass thickness smaller than or equal to 2.5 mm, and the flatness of the glass can reach 0.2 mm or below.
