Description

Float glass annealing kiln limit portion cooling tuyere rimq wind shield

Technical Field

The utility model belongs to the technical field of float glass annealing kiln auxiliary device, concretely relates to float glass annealing kiln limit portion cooling tuyere rimq windshield device.

Background

With the increasing market demand for glass raw sheets, the number of float lines has increased dramatically. At present, the float glass production capacity of China is the first in the world, and the glass requirement of more than 10mm for construction is continuously increased. Nowadays, the yield of thick glass is low during production, wherein the thick glass is easy to crack edges during annealing process and becomes one of the main factors influencing the yield.

At present, the edge roller method is mostly adopted in China, the transverse accumulation force of the edge roller is increased by increasing the number of pairs of the edge rollers, the edge rollers are directly accumulated to the required thickness, other auxiliary equipment is not needed in the method, the method is flexible to adjust, the process is simple and easy to operate, but simultaneously, a problem is caused, cold air is blown to the surface of glass in the annealing process of an annealing kiln after glass forming, generally facing the conveying direction of the glass, so as to achieve the annealing and cooling effects, the cold air is often directly obtained by pressurizing outdoor air, the outdoor temperature in summer is higher, the temperature of the cold air is higher, the temperature is slowly reduced during glass annealing, cracks are not easy to occur at the edge of the glass, the outdoor temperature in winter is lower, the temperature of the cold air is also lower, the cold air is directly blown to the surface of the glass, and because the edge is thin, the temperature can be very low, a very large temperature difference, the temporary tensile stress and the permanent stress of the side portion generated thereby are superimposed to place the side portion in a state of extremely large tensile stress, and thus the side portion is likely to be cracked.

In the disclosed patent "float glass annealing furnace" (patent No. 201020255419.9), the technical problem of edge crack of glass is reduced by adding a baffle at the position of an edge tuyere, but the baffle directly blocks the tuyere and cannot achieve good annealing and temperature reduction effects on the glass, so the use effect in actual production is not ideal.
