Choose the appropriate arc furnace
Electric arc furnace (EAF) is one of the main equipments for metal melting. Selecting suitable EAF according to different process needs can greatly improve the melting efficiency. In addition to considering the conventional factors such as the size and power of the furnace cavity, different types of electric arc furnaces should be selected according to the specific melting process, such as reactive electric arc furnaces, double electrode electric arc furnaces, gas cutting electric arc furnaces and other types to choose from.
Control the melting temperature
Melting temperature is one of the important factors affecting the efficiency of melting, generally according to the characteristics of raw materials and melting point to determine the melting temperature, and according to the specific situation to control the temperature rise and fall rate. Too high a temperature will lead to evaporation and severe oxidation of the raw material, reducing the melting efficiency, while too low a temperature will cause the raw material is not easy to melt, increasing the melting time and energy consumption.
Strictly control the ratio of raw materials
The reasonable ratio of raw materials can ensure the full reaction in the furnace and improve the smelting efficiency. In the smelting process, it is necessary to constantly adjust the ratio of raw materials, especially when blending coal, it should be adjusted according to the actual situation. When adding new raw materials, the raw materials should be melted before being added to prevent the raw materials from melting easily.
Increase the charge reserve
The amount of charge reserve should be determined according to the production task and furnace type, and it is generally recommended that the reserve amount be not less than 2-3 times the production task. The storage of sufficient charge can effectively improve the smelting efficiency and avoid frequent addition of insufficient charge in production.
Keep the equipment in good condition
The good condition of the equipment is an important guarantee to ensure the efficiency of smelting, and it needs regular maintenance and maintenance. It is recommended to check the equipment before each smelting to prevent faults from affecting the smelting progress.
In short, the improvement of the melting technique of electric arc furnace is of great significance to improve the production efficiency. Smelting manufacturers should take the appropriate skills according to the specific situation, give full play to the role of equipment, improve melting efficiency, reduce production costs.
