The invention provides a horizontal roller way type dinner plate toughening furnace and a production technology thereof, and relates to a toughening furnace. The toughening furnace comprises an upperpiece table, a conveying device, a heating furnace body, a die molding device, a die leveling device, a toughening blowing device, a toughening cooling device, a lower piece table and a supporting frame. The production technology of the horizontal roller way type dinner plate toughening furnace comprises the steps of glass preparation, uniform heating of toughening glass, sizing treatment of a glass die, leveling treatment of the glass die, cold air cooling and toughening treatment of the glass die and detection and measurement of the glass die. Main drive of the horizontal roller way type dinner plate toughening furnace is composed of an upper piece segment, a heating segment, a passing segment and a cooling segment, the technological process is continuous and disconnected, unbounded power and temperature are adopted to control and reduce temperature field stage change, so that heat absorption of same glass and different areas is more uniform, levelness of the glass is improved, the glass has a good toughening effect and good quality, the whole toughened glass yield is improved, and the working efficiency is high.
