Float process of flat glass with two forming lines in one melting furnace

Abstract

The invention discloses a flat glass float process with two forming production lines in a melting furnace, including raw material mixing, melting in the melting part of the melting furnace, cooling in the cooling part of the melting furnace, forming in a tin bath, annealing in an annealing kiln, cutting and taking pieces at the cold end, and melting in a melting furnace. The end of the cooling part is connected with a three-way glass liquid channel, the three-way glass liquid channel is composed of a liquid inlet, a glass liquid channel and two liquid outlets, the liquid inlet is connected with the cooling part of the melting furnace, and the two outlets The liquid ports are respectively connected to two flow channels, and the molten glass enters two independent tin baths through each flow channel for forming, annealing in an annealing kiln, and cold end cutting to form two forming production lines. The invention adopts the three-way glass liquid channel structure to realize the flat glass float process of two forming production lines in one melting furnace. Through the linkage adjustment of the two forming production lines, the melting capacity of the melting furnace is always in a fully saturated working state, which is a good solution. The melting capacity of the melting furnace is wasted, and two types of glass with different thicknesses can be produced at the same time. Two molding production lines of different sizes are used to make full use of the melting capacity of the melting furnace.

Description

[0001] technical field [0002] The invention relates to the field of flat glass float technology, in particular to a large tonnage flat glass float technology with one melting furnace and two forming production lines. Background technique [0003] The flat glass float production technology is mature. After decades of development, its process system has remained stable, and the temperature of the glass liquid flowing into the tin bath has fixed requirements. The existing flat glass float production technology is a flat glass float process with one melting furnace and one forming production line. End cut pieces. Furnaces are only able to reach their nominal capacity when producing glass of a certain thickness. In this form of production line, the melting capacity of the melting furnace is often in an incompletely saturated working state, resulting in a certain waste of the melting capacity of the melting furnace.

Problems solved by technology

[0004] Aiming at the deficiencies existing in the existing float process, the purpose of the present invention is to connect a secondary forming production line on the basis of the original forming production line to become a flat glass float process with two forming lines in one melting furnace. Linkage adjustment keeps the melting capacity of the melting furnace in a fully saturated working state, which solves the problem of wasting melting capacity of the melting furnace, and can also produce glasses of different thicknesses at the same time; the purpose is to connect two small melting furnaces with a large melting capacity Forming lines for molten glass requirements, such as thin flat glass forming lines
