This furnace is a new type of high-efficiency and energy-saving product, which is mainly used for the melting of various aluminum alloys, especially the melting places where there are many reflow materials such as aluminum profiles and aluminum products and the intermittent operation of a single furnace. Such as aluminum profiles, aluminum products, alloy plates and waste aluminum recycling.
Second, the main features:
1.Low energy consumption
High temperature flue gas is fully absorbed by the aluminum material in the shaft furnace during the upper row;
The furnace body is sealed and has good thermal insulation performance;
2.Low burning loss
The flame is far away from the furnace charge, and the aluminum material is immersed in the aluminum water to melt;
3.Even furnace temperature and aluminum temperature
Combustion proceeds along the tangential direction of the hearth furnace, and the furnace gas circulation is intense and evenly distributed;
4.Fast melting speed
Compared with the traditional square furnace, the round furnace can be melted while charging, so the furnace installation does not take up operating time, generally 2 to 3 hours can melt a furnace;
5. Low labor intensity
A. Forklifts or cranes are used to place bundles of aluminum ingots into the hopper once or twice, and then add them from the top of the furnace with a feeding mechanism, without manual handling;
B. The bundled aluminum ingots can also be hoisted on the feeding platform by a crane, and thrown by a manual or transmission mechanism after loosening the package;
6. Convenient operation, no dead angle for slag removal;
7, long furnace age, bottom furnace ≥ 4 years, shaft furnace ≥ 2 years.
Third, the main specifications and economic and technical indicators (excluding insulation):
1. Main economic indicators: It means that each furnace reaches the rated capacity, and the recharged material does not exceed 30% (clean material), and the rest are aluminum ingots. Under the condition that the furnace enters the state of thermal equilibrium and continues to work normally, the feeding from aluminum to aluminum liquid reaches 740. The index reached in the process of ℃.
2. The total height of the furnace body (H) and the height of the furnace top operating platform are appropriately adjusted according to the user's workshop conditions (driving height).
3. When using coal gas, the relevant indexes will change slightly when it reduces the low-calorific value or inferior fuel.
