Automatic steam treatment furnace

Automatic steam treatment furnace is based on the digestion and absorption of domestic and foreign advanced technology, through successful development  of a small volume, light weight, fast and convenient steaming starting and stopping, convenient protection and high energy efficient product. In the aspect of steam control system, that is a fully automatic steam treatment furnace, has advantages of safe and reliable performance.

Automatic steam treatment furnace mMain technical specifications and parameters:

Furnace pipe size: φ1200×1250;
Maximum loading size: φ1000×950;
The highest temperature: 650 ℃;
Heating power: 140kw;
Number of temperature control zones: Up, middle, below, three-zone temperature control + steam independent temperature control;
Temperature power adjustment type: SCR Zero-cycle, PID regulation;
Steam pressure adjustment: pressure sensors, pressure meters and electric actuator closed-loop PID control;
Operating system: PLC automatic process control, friendly man-machine interface, display and recording of process parameters;
Temperature control accuracy: ≤ ± 1 ℃;
Temperature uniformity: ≤ ± 5 ℃ (600 ℃, empty furnace);
Furnace design pressure: 0.1MPa (actual use as 0.07MPa).

Heating equipment (burner) release heat, water wall was first absorbed by radiation heat transfer, water in water wall boiling to produce a large amount of steam then into the drum to separate steam and water (except DC furnace), separated saturated steam enter into superheater, by radiation, and convection methods, continue to absorb the flue gas heat at top level of furnace, at end of flue channel, and make the superheated steam to achieve desired operating temperature.

Steam oxidation treatment furnace

Steam oxidation treatment furnace Type 1

Steam oxidation treatment furnace usage:

Steam oxidation treatment furnace used for formation iron-based powder metallurgy by sintering furnace to treatment surface oxidation, and also used as other mechanical parts black surface treatment.

Steam oxidation treatment furnace features:

1, Consist of furnace body, lifting mechanism, stirring fans, steam boilers, temperature control systems and other components.
2, Furnace body as circular shape, which composed by steel plate, furnace shell welded by structural steel and the use of ultra-lightweight refractory bricks, lining insulation materials, heating element placed on the shelf silk brick, hearth furnace with stainless steel welded into the furnace tank, while furnace cover fitted with loop mixing fan.
3, Heating elements are arranged in three zones, controlled subsection by import intelligent temperature instrument.
4, Temperature control system consists of thermocouple, digital intelligent PID regulator and solid state relays, form a closed loop control system, to realize automatic precise temperature control.


Steam oxidation treatment furnace Type 2

Oxidation furnace:

· Furnace pipe using 1Cr18Ni9Ti stainless steel.
· Insulation materials made of high quality aluminum silicate cotton.
· Electric heating using ribbon or filamentous alloy, easy maintenance.
· Unique hot air circulation system, so that the working chamber temperature distribution evenly.
· Use water jacket cooling fan and furnace lid.
· Various protective atmosphere can manually adjust the flow according to process requirements.
· Imported intelligent temperature control instruments with no overshoot expert PID algorithm, triggered by zero-power module to control the heating power. Divided into 2-3 temperature control zone by upper and down, so that the furnace temperature is more uniform.
· Equipped with power meter, which can calculate the power consumption.
· With over-temperature alarm system, when the furnace temperature exceeds the set range can audible alarm signals, and cut off the heating power.
· Independent control cabinet can conveniently control, also available with centralized control in the control room.
· Since the temperature is uniform, and there is a certain pressure steam in the oven, the product oxide film thickness of 5 ~ 8μm, with good compactness, and uniform hardness.
