Float glass production process.

Float glass production process.

The late 50s of last century, the United Kingdom Pilkington glass company announced to the world flat glass floatation process successfully developed, which is a groove on the molding process of a revolution. For a time, a float float flow into the "float mad Biao" swept the world. Many countries in the world at huge amounts of money to buy Pilkington patent, but Pilkington has made a technical blockade of China. Western technology blockade makes us realize that the development of Chinese float glass, production must go self-reliance, independent innovation. May 1971, the former National Building Materials Industry decided to float industrial test in Los glass, glass experts around the country gathered Los glass, Los glass more than a thousand workers to war.

Float glass production in China is unprecedented in a new business, because there is no reference for any information, the beginning of the experimental production to encounter a wave of another wave of problems. No designers, building materials, experts and the majority of scientific and technical personnel Luo Bo in the boiler room in the design, drawing sketch on the construction. There is no large lathe equipment, Luo Bo's fitter with a small furnace to cook the pot method, the scene processing 25 meters small tin slot. At that time in the production process encountered an important problem is: high temperature glass water through the tin tank when easy to condense, resulting in uneven glass thickness. Sometimes the glass of water in the tin bath in the chaos, the workers are full of injuries. Los glass technical staff after a long thought, in the upper part of the tin tank designed electric heating equipment, glass water through the tin tank easy to condense the problem solved. Then, they developed a glass puller machine, carefully designed speed, angle, pressure into the depth, and the shape of the shape of the process to be modified, the glass wider and wider, more and more flat, the quality is getting higher and higher. September 23, 1971, Luobo vast cadres and workers, under the leadership of the relevant experts under the guidance of the brothers in the full cooperation, unity and fighting for more than three months, and finally successfully built the first float Glass production line, to produce China's first piece of float glass. Mechanical strength, flatness, transmittance are better than other flat glass. Lobo by virtue of Superman's wisdom and hard work, round the Chinese float dream.

From 1971 to 1981, Lobo has three times in this line on the implementation of a large-scale technological transformation, the production line melting capacity of 225 tons, plate width of more than 2 meters, the total yield reached 76.96%, and by the end of 1978 to Early 2009 to produce a thin 4 mm glass, "Luoyang float glass technology" technology and equipment is also improving, the technical level continues to improve.
April 27 to 30, 1981, the State Science and Technology Commission organized the national glass experts and scholars and relevant departments in Los Angeles held "Luoyang float glass technology" national technical appraisal meeting, which is China's following tons of tons, Hydraulic press after the third national technical appraisal meeting, the meeting will be officially named this process as China "Luoyang float glass process", awarded the invention of the invention of gold award. "Luoyang float glass process" in the birth of Los glass, the end of an old era, ushered in the development of China's glass industry a new dawn, opened up China's glass industry reform, innovation and development of a new era for China's glass industry The development of a magnificent monument, became the world's glass industry with the British Pilkington float, the United States Pittsburgh float to keep pace with one of the world's three major float process.
