Abstract

The invention relates to a cutting and plate-breaking process for hot glass on a production line for manufacturing float 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 float 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 surface size of the glass plate obtained by the process is accurate, the cutting track is straight, the cutting edge is neat and free of edge breakage, the float glass can be cut in a high-temperature state, and necessary technical guarantee and possibility are provided for further online processing of the float 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 production line for manufacturing float glass. Background technique [0002] The traditional float glass production process is to heat quartz sand, limestone, soda ash and other materials to about 1400 ℃ to melt, and then go through clarification, flattening, drawing, cooling, cutting and other processes. After production, the float glass can be further processed, such as tempering, lamination, etc. Tempered glass is a glass deep-processing product obtained by cutting flat glass into the required size, heating it to about 600°C close to the softening point, and then rapidly and uniformly cooling it. Tempered glass has many advantages, safety and high strength, and is widely used in construction and transportation. tools, furniture, etc. [0003] In the traditional float glass production process, the heat ener...
