Embodiment 1

[0041]On the 600t / d float production line, the original plate width is 4000mm, and when producing 5mm glass, the main line glass plate speed is 8-9m / min. The size of the board after online cutting is 3662×2442mm, and it is trimmed and polished.

[0042] In the trimming and polishing process of hot glass on the production line for manufacturing float glass, the temperature of the high-temperature glass is 500-650°C, and the specific process is as follows:

[0043] (1) After the longitudinal edge breaking process in area B of the annealing kiln of the flat glass float production line, the glass plate 1 enters the longitudinal edge trimming and polishing area. The kiln roller table runs at a suitable speed, and the longitudinal trimming and polishing unit parts arranged on both sides of the annealing kiln run to the middle of the annealing kiln at the same time, so that the V-shaped groove 2 of the polishing wheel touches the longitudinal edge of the glass. When the flame gun is...

Abstract

The invention relates to a trimming and polishing process for hot glass on a production line for manufacturing float glass. According to the process, a longitudinal trimming and polishing device and a transverse trimming and polishing device are used for carrying out longitudinal trimming and polishing treatment and transverse trimming and polishing treatment on a high-temperature glass plate on the float glass production line. According to the high-temperature glass trimming and polishing process, longitudinal trimming and polishing treatment and transverse trimming and polishing treatment are carried out in sequence, the treated glass enters the next deep processing procedure, the edge of the glass subjected to the trimming and polishing procedure does not need to be subjected to edge grinding treatment in the later period, and the process is carried out on a float glass production line at the temperature of 500-650 DEG C, so that the high-temperature glass is obtained. The whole process is operated at high temperature, the glass treated by the process is accurate in size, the trimmed edge of the glass is flat, smooth, neat and free of edge breakage, the edge quality of the glass is far superior to that of a product produced by a traditional glass edge grinding process at normal temperature, and the technical requirement of glass deep processing is completely met.

Description

technical field [0001] The invention belongs to the technical field of glass deep processing, and in particular relates to a trimming and polishing process of hot glass on a production line for manufacturing float glass. Background technique [0002] Float glass is named after molten glass floating on the surface of molten metal to obtain polished molding. The molten glass flows continuously from the furnace into a tin bath filled with protective gases (nitrogen and hydrogen) and floats on the surface of the metal tin. In general, the glass that has been flattened and polished to form a glass ribbon with uniform thickness, parallel surfaces, flat and polished glass is a type of flat glass. [0003] After hot cutting / segmentation and cutting at high temperature (500-650°C) on the float glass production line, the glass needs to be trimmed and polished at high temperature, which can ensure the quality of the next step of processing, and ensure the safety and reliability of the ...
