A. Advantages and development trends of induction melting furnace

(1) Advantages of induction melting furnace ，Induction melting furnace has easy to change smelting varieties, easy to control melting temperature, uniform chemical composition and easy adjustment, easy to control melting quality, flexible and simple operation, high power density, fast melting speed and high thermal efficiency. Convenient melting, low labor costs, and energy saving and environmental protection.

(2) Development trend of induction melting furnaces Developed countries such as Europe, the United States and Japan have purchased a large number of castings in China. The domestic metallurgical foundry industry has developed rapidly. The demand for induction melting furnaces has risen steadily. The world-class electric furnace manufacturers are expensive due to price, service and spare parts. For other reasons, the Chinese market is shrinking, and the production and application technology of domestic induction melting furnaces are developing rapidly, making some products close to or reaching the world's advanced level. Although there are still gaps, they are quite good due to reasonable prices and good service quality. Market share and move to the international market. The foundry industry is increasingly demanding the economics of smelting equipment, energy saving and environmental protection, smelting quality, automation, operation flexibility and reliability, and ease of maintenance and repair. In addition to the application of computers, the energy supply mode continues to improve. , automatic monitoring and testing, greatly promoted the development of manufacturing and application technology of induction melting furnace melting equipment, this trend shows that induction melting furnaces occupy a dominant position in the melting equipment of the foundry industry. Large-scale, high-power density, intelligent, high-reliability, high-security, high-quality, high-quality service and energy-saving and environmental protection are the development trends of induction melting furnaces.

B. Problems and solutions for the application and development of induction melting furnace

1. Problems in the application and development of induction melting furnace

The current problems in the application and development of induction melting furnaces are as follows:

(1) Stability, reliability, and safety are expected to be further improved.

(2) Further improvement is needed in intelligent controllable operation technologies, including fault analysis and prompts.

(3) Most of the comprehensive energy conservation and environmental protection indicators do not meet the requirements of industry access standards.

(4) There is no uniform national standard including the technical parameters and the structure of the equipment itself, and the parts are all the same.

(5) Due to the development of integrated circuits and the technical blockade of manufacturers, most users have problems in maintenance and maintenance. Some induction melting furnace manufacturers have no guarantee of service, slow response, spare parts are non-standard and expensive, and Due to price competition, the quality of electrical components is also worrying.

(6) The user lacks technical guidance at the initial use, takes a lot of detours, or develops many bad habits.
