Glass electric melting 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. It is currently the most advanced glass melting technology in the world. It is an effective way for glass manufacturers 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.
Advantages of glass electric melting technology:
1. The volatilization of the batch components 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 glass liquid in the molten pool basically experiences the same thermal history, which greatly improves the uniformity of the glass, plays a key role in eliminating bubbles, streaks, stones and color differences of the products, especially in preventing cracks and explosions, and improves product quality.
2. The electric melting furnace has basically no exhaust gas emissions, no waste slag and waste liquid, low noise pollution, low heat radiation, and a good working environment. Green and clean production meets national environmental protection requirements.
3. The electric melting furnace has high melting efficiency. The all-electric melting furnace relies on the glass's own electrical conductivity to achieve internal heat melting. There is no large amount of heat taken away by smoke emission, and its thermal efficiency can reach more than 70%.
4. The electric melting furnace is easy to fully automatically control, has a wide operating range, stable thermal system, high sensitivity and precision, and high control efficiency.
5. The electric melting furnace occupies a small area, is easy to operate, has a fast overhaul time, and has high labor productivity.
6. The electric melting furnace responds to the national industrial policy and sustainable development strategy, takes the initiative in the case of changing energy at home and abroad, takes the lead in the fierce product market competition, and wins the first opportunity in improving the technical management level of enterprises.
The all-electric melting furnace is the application of multi-disciplinary comprehensive supporting technologies of melting furnaces, refractory materials, machinery, electrical, chemical industry, and automation control, and is a production process in the field of high technology. Since its advent, it has quickly been recognized and widely adopted by the industry. Practice has proved that the economic benefits brought by this technology are huge and are a reliable guarantee for the upgrading of enterprises.
