The oxidation loss of the aluminum ingot heated by the aluminum rod heating device can be controlled below 0.05~0.5% , and the heating loss in the furnace is generally 2.5~3.0% , so the induction heating furnace generally does not need gas protection. The main body of the induction has only one inductor. This kind of furnace does not require a complicated piping system like a burning furnace, and does not require a burning furnace. It has a thick furnace wall, so it can be compactly organized in the production line or even combined. In other processing machines.

What parameters are required for the selection of aluminum rod heating equipment ?
The selection of aluminum rod heating equipment generally requires the following parameters:
First: the shape of the heated aluminum ingot, the outer dimensions, the weight of the workpiece being heated.
Second: the material material of the heated workpiece (generally induction heating, only for metal conductor materials).
Third: the time of the target temperature required for heating the heated workpiece, and the target temperature.
Once the above three points are clear, the bar heating furnace can be selected including matching power.
What are the characteristics of the aluminum rod heating equipment structure?
1. Furnace structure: Our company's heating furnace is designed as an overall quick change type. Quick change is possible when changing the furnace body for different heated workpieces.
2. Furnace lining: The lining is made of silicon carbide or integral knotting, and the temperature is above 1450 °C.
3. Protection: Automatic shutdown when the water temperature exceeds 65 °C.
4. Induction furnace water cooling rail: Water-cooled rail is installed on the induction furnace lining.
How to calculate the power of aluminum rod heating equipment ?
P=(0.168×200×693)/(0.24×0.6×145)=1029KW In the formula: 0.168—the average specific heat of the ferrous metal; 2080—the mass of the workpiece (Kg); 200—the temperature rise of the workpiece heating; 0.24— Work heat equivalent; 0.6 - average efficiency (0.6 in this case, generally 0.5 ~ 0.65, lower profile sensor, take 0.4); 145 - work beat (seconds)
According to the above calculation, a 1KHz induction heating device with a rated power of 1500 KW can be configured to meet the needs.
How to choose and use aluminum rod heating equipment ? Mainly from several aspects:
1. Shape and size of the heated workpiece
For large workpieces, bar stocks and solid materials, bar heating furnaces with relatively high power and low frequency should be used; for small workpieces, pipes, plates, gears, etc., the bar heating furnace with relatively low power and high frequency is used.
2. Depth and area required for heating
The heating depth is deep, the area is large, and the whole heating should be selected. The bar heating furnace with high power and low frequency should be selected; the heating depth is shallow, the area is small, local heating, and the bar heating furnace with relatively low power and high frequency is selected.
3, the required heating rate
The required heating speed is fast, and a bar heating furnace with relatively large power and relatively high frequency should be selected.
4, the continuous working time of the equipment
The continuous working time is long, and the bar heating furnace with a slightly larger power is used.
5, the connection distance between the sensing component and the device
The connection length is long, and even the use of water-cooled cable connection is required. The medium-frequency induction heating furnace with higher power should be used relatively.
6, process requirements
In general, quenching, welding and other processes, relatively power can be selected smaller, frequency selection is higher; annealing, tempering and other processes, relative power selection is larger, frequency selection is lower; red punch, hot calcination, smelting, etc., need For a heating process, the power should be chosen to be larger and the frequency selected lower.
7, the material of the workpiece
The relative power of the high melting point of the metal material is larger, the relative power of the lower melting point is smaller, the power of the smaller resistivity is larger, and the power of the larger resistivity is smaller.
