2. Working temperature: 700 ± 25 degree
3. Furnace chamber
A.Furnace length: 32.5m, overall length including loading & unloading: 37.5m.
Furnace liner lower part is high-temperature cast structure, upper part is heavy brick or cast module. Between the furnace body and furnace liner is insulating layer made from Aluminum silicate fiber cotton. To ensure the ability of keeping the temperature.
B.Each section of furnace: L2500*W1350*H1450mm, inner hole size 650mm.
C.Out shell is made from angle iron and steel sheets. The bottom is made from steel structure, channel steel, with steel sheets, due to the high pressure.
Between each section of furnace, they are connected by angle steel flange, easy to install and adjust.

C. Frequency Electrical Furnace:




 

I. Frequency heating principle:

Frequency heating is using frequency power to change 380V, 50Hz power current into the suitable frequency current by rectification and contravariant. Input this current into resonant tank composed by the heating furnace, to make the furnace coil produce alternating magnetic field, while the pre-heating metal material stay in the alternating magnetic field, the material will produce the alternating current and heating by itself, high hot efficiency and low energy consumption.

Feature:

Frequency induction heating power factor≥96%, has automatic impedance adjustment function, the performance of energy saving is obviously.

Power output is steady, heating temperature is easy to control, good consistency to improve the heating quality.

Good diathermancy, magnetic field has a good permeability to the metal workpiece, it's not heating conduction, so the temperature difference of workpiece movements is small and improve the products' quality.

Temperature measuring system closed-loop control heating power, the precision of temperature is high.

Automatic impedance adjustment and automatic frequency adjustment function, inspecting system impedance transformation caused by the cylinder from cool to hot during the whole heating process automatically. Adjusting the output parameter automatically and making the whole heating process stay in energy-efficient state, saving more power.
 

II. Heating process requirement:

9KG, 14KG LPG cylinder production line:

FAQ

1:size of cylinder(for instance length, diameter, thickness, 15, 50 kgs)

2:material of cylinder(carbon steel or stainless steel)

3:application of cylinder  such as LNG(Liquid natural gas) or LPG( liquid petroleum gas).

4:workingtemperature,Sometimes we need to weld copper tube inside the cylinder if the liquid in the cylinder is very low temperature.That's why we need to know the temperature and liquid in the cylinder,whether it is oxygen or nitrogen?

If you can provide technical drawings will be highly appreciated.
