The present invention provides a device for preheating, heating, and cooling thin glass in a sequential process, the apparatus comprising: a preheating furnace (20) having a heat insulating wall structure that can be opened and closed upward and performing a heating function by using a blower; A main body 30 having a plurality of fireproof wall structures which can be opened and closed upward, and which performs indirect heating on at least one side; A cooling furnace 40 having a plurality of heat insulation wall structures that can be opened and closed upward, and maintaining cooling by using a blower together; A rail (60) installed in parallel on the preheating furnace (20), the main body furnace (30), and the cooling furnace (40) and having a rack (62) on at least one side; And a first chamber 73 having a heater and a second chamber having a heater, which is installed to run on the rail 60 via a support roller 61 and a driving wheel 63. It characterized in that it comprises a; (74) integrally provided with a feed cart (70).n n n Accordingly, the present invention has the effect of improving the quality and productivity by inducing a stable and smooth flow between processes in the process of automatically performing heat treatment for the surface hardening of the thin glass. |
