LPG cylinder annealing / stress relieving furnace
LPG Cylinder Annealing / Stress Relieving Furnace

Introduction for heat treatment furnace

      Continuous cylinder heat treatment nature gas heat treatment furnace is widely used for heat treatment of steel cylinder. The heating of the furnace is divided into two sections. One section is the heating section (horizontal); the second section is the high temperature section (horizontal).

Normalizing Furnace

 LPG Cylinder Annealing / Stress Relieving Furnace

Parameter and requirements:

1.Continuous heat treatment furnace: total length for this machine is 20 meters(furnace is 15 meters, loading & unloading holder is 5 meters). The furnace is welded by high quality section steel, the furnace is lined with high temperature resistant high alumina refractory firebrick, insulation layer is made of fiber and other thermal insulation materials. Overall, the high temperature furnace is light and of good insulation performance.

B: Annealing Furnace

LPG Cylinder Annealing / Stress Relieving Furnace

Parameter:


1. No of burning nozzle: 150000Kcal, totally 8 pieces.
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:

Workpiece size: 9KG, 14KG LPG cylinder

Heating temperature: 780 - 900°C (The heating temperature sets according to the technology demand, adjustable)
