Sheet Glass Manufacture: the Float Process. Glass, which has been made since the time of the Mesopotamians and Egyptians, is little more than a mixture of sand, soda ash and lime. When heated to about 1500 degrees Celsius (°C) this becomes a molten mass that hardens when slowly cooled. The first successful method for making clear, flat glass ...
A float line is almost like a river of glass that exits the furnace before its cooling process. It makes its way to nearly 300 meters, after which it is cut into large sheets; these sheets typically measure 3.21x2.25 meters.

The Step-by-step Manufacturing of Float Glass Watch the magic of this science-based process begins to unfold, in a series of stages on a float line that may be nearly half a kilometre long. Raw materials enter at one end. From the other, plates of glass emerge, cut precisely to specification, at rates as high as 6,000 tonnes a week.

The float glass process, which was originally developed by Pilkington Brothers in 1959 (Haldimann et al., 2008), is the most common manufacturing process of flat glass sheets. More than 80–85% of the global production of float glass is used in the construction industry ( Glass for Europe, 2015a ).

Float glass is a sheet of glass made by floating molten glass on a bed of molten metal, typically tin, although lead and other various low-melting-point alloys were used in the past. This method gives the sheet uniform thickness and very flat surfaces. [1] Modern windows are made from float glass. Most float glass is soda-lime glass, although relatively minor …
A float plant, which operates non-stop for between 10-15 years, makes around 6000 kilometres of glass a year in thicknesses of 0.4 mm to 25 mm and in widths up to 3 metres. The float …

At the heart of the world's glass industry is the float process - invented by Sir Alastair Pilkington in 1952 - which manufactures clear, tinted and coated glass for buildings, and clear and tinted glass for vehicles. The process, originally able to make only 6mm thick glass, now makes it as thin as 0.4mm and as thick as 25mm.

Sheet glass manufacture: the float process Sản xuất kính tấm: quy trình nổi Glass, which has been made since the time of the Mesopotamians and Egyptians, is little more than a mixture of sand, soda ash and lime.
This part of the process rubbed away around 20 per cent of the glass, and the machines were very expensive. The float process for making flat glass was invented by Alistair Pilkington. This process allows the manufacture of clear, tinted and coated glass for buildings, and clear and tinted glass for vehicles.
Forming: The molten glass is formed into a flat sheet by a float glass process. The sheet is fed onto the surface of a bath of molten tin, where it is cooled and shaped. 4. Annealing: The glass is annealed, or slowly cooled, to relieve stresses in the glass and to strengthen it. ... manufacturing. Float glass is a type of sheet glass made ...
