Toughening furnace for continuously producing half strengthened glass and production method of toughening furnace

Abstract

The invention provides a toughening furnace for continuously producing half strengthened glass and a production method of the toughening furnace. The toughening furnace is characterized by comprising a feeding area, a heating area and the like arranged orderly, wherein the feeding area has a two-way feeding function; and the heating area comprises a first heating section, a second heating section and a third heating section. The production method of the toughening furnace comprises the following steps of heating treatment, cooling treatment and the like. The toughening furnace has the beneficial effects that the heating area is divided into three heating sections; the length of each heating section is 10m; the length of the heating area is greater than that of like product; the three heating sections adopt different temperature to heat; the glass can finish the heating requirement of the half strengthened glass after passing through the three heating sections; conveying for a plurality of times is not needed; and the rear glass does not need to wait in the feeding area, so that continuous heating of the glass is achieved; and the work efficiency is improved. The production efficiency of the toughening furnace is 3.5 times that of a common double-chamber toughening furnace, and is 5.5 times that of a common single-chamber furnace; and the energy consumption of each square meter of glass is reduced by about 39% in comparison with that of the common toughening furnace.

Description

[0001] technical field [0002] The invention belongs to the field of glass manufacturing, in particular to a tempering furnace for continuously producing semi-tempered glass and a production method thereof. Background technique [0003] Semi-tempered glass is a kind of glass between ordinary flat glass and tempered glass. It has some advantages of tempered glass, and its strength is higher than that of ordinary glass. At the same time, it avoids the poor flatness of tempered glass and is easy to explode. Destruction is a weakness such as overall smashing. When semi-tempered glass is damaged, it will crack radially along the crack, usually without cracks, so it will not shatter and collapse when it is damaged. Most semi-tempered glass production currently uses heat treatment methods, usually using single-chamber or double-chamber furnaces. But the processing efficiency of single-chamber furnace and double-chamber furnace is slow. The reasons for the slow processing effici...

Problems solved by technology

The back-and-forth transfer caused the back glass to wait for a long time at the entrance of the tempering furnace

2. During the cooling process of the glass, due to its property that the stress of semi-tempered glass is smaller than that of fully tempered glass, the wind blowing strength is very weak. In addition, the length of the cooling section is limited, and the glass must be transmitted back and forth in the cooling section.

The above two reasons lead to the inability of the single-chamber furnace and the double-chamber furnace to realize the continuous production of semi-tempered glass
