Continuous tempering furnace and processing technique of bent tempered glass

Abstract

The invention relates to a continuous tempering furnace used for processing bent tempered glass, comprising a heating furnace and a quenching air duct. The front end and the rear end of the heating furnace are respectively provided with a feed port and a discharge port, respectively. The heating furnace consists of a hot forming region, a glass balanced heat-preservation region and a fast heating region which are arranged sequentially. A track and a driving device are arranged at the bottom of the heating furnace and the quenching air duct. A plurality of mobile trolleys running through the heating furnace and the quenching air duct run on the track, and the mobile trolleys are driven to run by the driving device. The invention further discloses a processing technique of bent tempered glass utilizing the tempering furnace. The tempering furnace has reasonable structure, high production efficiency, convenient operation and high energy utilization rate.

Description

technical field [0001] The invention relates to a continuous tempering furnace for processing bent tempered glass and a process for processing bent tempered glass by using the tempering furnace. Background technique [0002] The tempering of glass is to heat ordinary glass to a temperature close to softening, also called tempering temperature, and then rapidly cool the glass. After tempering, the surface of the glass forms a uniform compressive stress, while the interior forms a tensile stress, making the strength and stability of the glass Significantly improved performance and safety. The existing curved tempered glass production equipment usually consists of a loading and unloading area, a forming heating furnace, and a quenching area. There is an opening on one side of the forming heating furnace. After the tank is sent to the forming heating furnace, the glass is formed in the forming heating furnace and heated to the tempering temperature, then the furnace door is ope...

Problems solved by technology

The existing curved tempered glass production equipment usually consists of a loading and unloading area, a forming heating furnace, and a quenching area. There is an opening on one side of the forming heating furnace. After the tank is sent to the forming heating furnace, the glass is formed in the forming heating furnace and heated to the tempering temperature, then the furnace door is opened, and the trolley is pulled back to the quenching zone, and the glass is rapidly cooled in the quenching zone to obtain a finished bent tempered glass , this kind of tempering furnace can only be operated once during processing, and it is always in an idle state during the period when the glass is quenched and cooled until the next time ordinary glass is added, the heat energy is wasted, and the production efficiency is low and the time is long, making the production cost relatively high. In addition, the furnace chamber structure design of this kind of tempering furnace is unreasonable, and the quality of the processed bent tempered glass is difficult to guarantee
