Glass electrofusion technology is a new technology that uses the resistance of the glass melt to generate Joule heat to melt glass. It has advantages that traditional flame furnaces do not have, and is currently a relatively advanced glass melting technology internationally. It is an effective way for glass production enterprises to improve product quality, reduce energy consumption, and reduce environmental pollution. It is one of the key promotion projects of the Ministry of Science and Technology of the People's Republic of China.
Advantages of glass electric melting technology:
1. The volatilization of the batch composition of the electric melting furnace is only 3-5% of that of the flame furnace, which greatly improves the chemical stability of the glass. In addition, all the liquid glass in the melting pool basically experience the same thermal history, which greatly improves the uniformity of the glass, and plays a key role in eliminating bubbles, stripes, stones and color differences of products, especially in cracking and explosion prevention, and improves the product quality.
2. Electric melting furnace basically has no waste gas emission, no waste residue and waste liquid, low noise pollution, low thermal radiation and good working environment. Green and clean production, meeting the national environmental protection requirements.
3. The electric melting furnace has high heating efficiency. The all electric melting furnace realizes internal heating melting by means of the glass's own conductivity, without a large amount of heat taken away by flue gas emission, and its thermal efficiency can reach more than 70%
4. The electric melting furnace is easy to be fully automatic controlled, with wide operating range, stable thermal system, high sensitivity and accuracy, and high control efficiency.
5. Electric melting furnace occupies less land, is easy to operate, has fast overhaul time and high labor productivity.
6. In response to the national industrial policy and sustainable development strategy, the electric melting furnace takes the initiative under the changeable domestic and international energy sources, takes the lead in the fierce product market competition, and wins the first opportunity in improving the enterprise's technology management level.
The all electric melting furnace is the application of comprehensive supporting technologies of melting furnace, refractory, machinery, electricity, chemical industry and automation control, and belongs to the production process of high-tech field. Since its inception, it has been recognized by the industry and widely adopted. Practice has proved that the economic benefits brought by this technology are huge, and it is a reliable guarantee for enterprises to upgrade.
Our company has cooperated with Professor Ning Wei of the Glass and Enamel Research Institute of Donghua University for many years, making our company's electric melting furnace technology always in the leading position in the industry, laying a good foundation for customers to provide advanced process design, advanced furnace design and achieve high-quality projects, so that users' technology and equipment have reached a higher level and become the forefront of the industry.
