Abstract

The invention relates to a cutting and plate-breaking process for hot-state glass on a production line for manufacturing rolled glass, which is characterized in that a transverse cutting and plate-breaking device and a longitudinal cutting and edge-breaking device are arranged on the rolled glass production line, and a high-temperature glass tape is kept in a high-temperature state of 500-650 DEG C for cutting and edge-breaking treatment. The glass plate obtained through the process is accurate in surface size, the cutting track is straight, the cutting edge is neat and free of edge breakage, the rolled glass can be cut in the high-temperature state, and necessary technical guarantee and possibility are provided for further online machining of the rolled glass.

Description

technical field [0001] The invention belongs to the technical field of glass processing, and in particular relates to a cutting and breaking process of hot glass on a rolling glass production line. Background technique [0002] The traditional rolling glass production process is to heat quartz sand, limestone, soda ash and other materials to about 1400 ℃ to melt, and then process them through clarification, drawing, cooling, cutting and other processes. Rolled glass can be further processed after production, such as tempering. Tempered glass is a glass deep-processing product obtained by cutting rolled glass into the required size, heating it to about 600°C close to the softening point, and then cooling it quickly and uniformly. Tempered glass has many advantages, safety and high strength, and is widely used in photovoltaics and construction. , Household, etc. [0003] In the production process of traditional rolling glass, the heat energy is directly discharged during the...
