The picture of the 560t / d online LOW-E energy-saving smart glass manufacturing production line taken at Yaohua Glass Technology Development Co., Ltd. in Qinhuangdao on December 19, 2019.
China Yaohua Glass Group Co., Ltd., located in Haigang District, Qinhuangdao City, Hebei Province, was founded in 1922 and is known as “the cradle of the glass industry in China”. In 2017, according to the national capacity replacement requirements, and after the implementation of “reduction replacement” at a ratio of 1.25: 1, Yaohua Group implemented the technical transformation project of the 560t / d online LOW-E energy-saving smart glass manufacturing based on two float glass production lines of 300t / d and 400t / d in accordance with the principles of “inventory optimization and incremental development” of Yaohua Group determined by Qinhuangdao Municipal Party Committee, Municipal Government, and China Building Materials Kaisheng Technology Group.
This project was put into operation in June 2018 after the construction of more than a year relying on the advantages of the building materials technology in China, adopting the production line of constant-speed production process with a wide plate, with the total investment of 510 million yuan. The production line can realize the mass production of high-quality thin-plate glass with a maximum original plate width of 5200mm without reducing the pull-in quantity. It breaks through the technical limit of reducing the pull-in-quantity in the production of thin-plate glass with the same melting amount, which takes the leading level in China. Through the continuous trial production test, the cold end optimization system has been successfully debugged with the glass production capacity of 1.6mm and above. The products are mainly used in the automotive, electronics, high-end mirror making, and home appliances and other fields, to achieve the transformation and upgrading of the enterprise, and revitalize the old industry.
