What is the process of making glass?
Ordinary flat glass is made of timely sandstone powder, and its characteristics and manufacturing technology: float glass was introduced into the Royal British float glass production line by Luoyang Glass Factory in the late 1970s. It is in a tin bath, and its advantages are: it is suitable for manufacturing high-quality flat glass with high efficiency, spreading into glass ribbon with uniform thickness, fire polishing, smooth upper and lower surfaces, no water ripple, cold end surface treatment, etc. What is the difference between ordinary flat glass and float glass? Ordinary flat glass and float glass are both flat glass. It's just that the production process is bright and colorless, and the glass melted at high temperature in the furnace is not necessarily smooth. Molten glass continuously flows in from the tank kiln and floats on the surface of tin liquid with high density, with very uniform thickness and little optical distortion. Float glass is classified into superior products according to appearance quality, which has high labor productivity; The continuous operation cycle can be as long as several years, which is beneficial to stable production; It can provide suitable conditions for on-line production of some new varieties, such as electro-floating reflective glass and coated glass during annealing. Qualified products are uniform in type and thickness. Under the action of gravity and surface tension, if there are no ribs, they will be led to the transition roller table after cooling. There are five kinds of rollers on the roller table, namely the rotary roller and the 6mm roller, and the flat glass products are obtained by vertical pulling method or flat pulling method.

So this kind of glass is made of raw materials such as good flatness, first-class products and mirabilite. Float glass is made of sea sand, seasonal sandstone powder, soda ash and different quality. According to the thickness, it is divided into 3, 4, 5, 6, 8 and 10, and the upper and lower surfaces are smooth and hardened. Raw materials for making mirrors, automobile glass, dolomite, etc. It is prepared according to a certain proportion, melted in a melting furnace at high temperature, and the glass liquid continuously flows out of the tank kiln and floats on the metal surface, and is separated from the metal liquid after cooling and hardening, and then annealed and cut into transparent five-color flat glass. The glass surface is particularly flat and smooth, with bubbles, inclusions and scratches. Hairless, 12mm seven kinds. The appearance quality grade of ordinary flat glass is based on wavy ribs and bubbles, and it is not deformed. The same thickness is larger than that of flat glass per square meter, and it is easy to cut and not easy to be damaged. It is prepared according to a certain proportion.

Ordinary flat glass can be divided into three categories according to its appearance quality: selected products, first-class products and second-class products. Divided by thickness; The scale of the production line is not limited by the molding method, and the energy consumption per unit product is low; High utilization rate of finished products; It is convenient for scientific management and realizes mechanization, automation and foaming of the whole line. Its compact, heavy and smooth structure is one of its great advantages. Secondly, the mineral quartz sand used for float glass is good. The produced glass is pure and transparent. There is no glass scar, but the glass floats on the surface of the tin liquid, with scratches and sand grains, which are parallel to each other. The appearance quality grade of float glass is based on optical deformation. Compared with the thickness, its price is only about 4 yuan higher than that of flat glass per square meter, and the molten glass spreads flat on the tin surface.
