Floating method refers to the method of glass floating on the surface of molten metal to produce flat glass.
Its use is divided into two categories depending on whether it is colored:
Transparent floating glass-for construction, furniture, decoration, vehicles, mirror panels, optical instruments.
Color float glass -- for construction, vehicles, furniture decoration.
Floating glass has a wide range of applications: flotation silver mirrors, automobile windscreens, flotation glass deep processing grades, flotation glass scanner grades, flotation glass coating grades, flotation glass mirror grades. Among them, ultra-white floating glass has a wide range of uses and broad market prospects. It is mainly used in the fields of architecture, glass processing and solar photoelectric curtain walls, as well as glass furniture, decorative glass, imitation crystal products, lamps, precision electronics industries, and special buildings.
The forming process of floating glass production is completed in a tin slot that enters the protected gas(N2 and H2). The molten glass flows continuously from the pool kiln and floats on the relatively dense tin liquid surface. Under the action of gravity and surface tension, the glass liquid is spread on the tin liquid surface, flattened, formed on the upper and lower surfaces, hardened, and cooled. After being introduced into the transition roller. The roller of the roll table rotates and pulls the glass belt out of the tin trough into the annealing kiln. After annealing and cutting, floating glass products are obtained.
A linear motor is a device that converts electrical energy directly into linear motion mechanical energy. When the three-phase winding of a linear motor enters the current, a "traveling wave magnetic field" is generated. The conductor in the "traveling wave magnetic field" is induced by cutting the magnetic force line. Current, The interaction between the current and the magnetic field produces electromagnetic forces. In the tin tank, this electromagnetic force promotes the movement of tin fluid. By adjusting the parameters of the motor, it can easily control the direction and speed of the flow of tin fluid.
The linear electric machine causes heat transmission. A linear motor is installed on the head of the tin tank. At the same time, an active guide plate is used to introduce Gaowenxiye into the outside of the graphite wall, flow down the direction of the glass movement, and return to the middle of the tin trough at the end of the retaining wall., and then backflow in the opposite direction toward the plate root, During the reflux process, heat is continuously absorbed, and the head is once again led to the edge by the linear motor to achieve the function of transporting heat.
The use of linear motors in appropriate locations in the polishing area can improve the variability angle. Different types of linear motors and operating parameters are selected according to factors such as tin tank tonnage, thinning process, glass grade, etc.. It has been proved that under the same conditions, Using linear motor average can increase the variability angle by 3-7 degrees.
The principle of action of the linear motor is to produce a controllable lateral tin flow in the polishing area. This flow produces a "caress" effect on the surface of the glass, and the uneven microarea of the surface can disappear, and the temperature of the polishing area is uniform, and the self-polishing effect can be played..
The role of linear Motors is mainly summarized as follows: 1. Improve the surface quality of thin glass and improve the thickness difference. 2. Stable thick glass forming weight. 3. Stabilize the glass belt to prevent the drawing machine from breaking off. 4 Transfer electric heating heat, homogenize temperature. 5 Reduce horizontal temperature difference, favorable good annealing. 7 Prevent tin from spilling at the exit.
