The C-bent section of LandGlass’ C-bent glass tempering furnace employs a fully integrated welding rack. The main components comprise of a cooling system, a drive system, a servo controlled bending system and an air control system. The cooling system is formed by an upper and lower chiller, air boxes and air pipes; the drive system is formed by a variable-frequency motor, decelerator and a roller bed that can execute lateral bending; the servo controlled bending system is primarily formed with an upper and lower chiller bending structure and arc-adjusting structure; the air control system is formed by the shutter, air release valve, air distribution boxes, etc.
