650 Ton/month High Quality Automatic Aluminum Anodizing Line

650 Ton/month high quality automatic aluminum anodizing line

一. Product description:

1.Anodizing production line is a common metal surface treatment process, which improves the corrosion resistance, hardness, and wear resistance of metal materials by oxidizing the metal surface in acidic electrolyte, and endows them with a beautiful appearance.

2.Anodizing is the process of anodizing a metal surface in an acidic electrolyte to form a dense oxide film on the metal surface.

3.Oxide film has high corrosion resistance and hardness, which can effectively protect metal materials from external environmental damage.

   (4) Unprocess time: 10min
   (5) Total time 30+10=40min

(6) Average anodizing layer : 0.36*1.3*30*0.77 =10.81um

5. Colour 1

1) Clour process: Mix Salts

2) Quantity: 2 jig(rack)/tank x 1tanks = 2jig(rack)

3) Current density: 70A

4) Process time: 2-8min

6. Sealing
1) Sealing menthod: Sealing at Medium or Normal Temperature
2) Quantity:6jig(rack)/tank x 1 tank
3) Process time 10-15min

六. Design Parameter and Setting

1. Anodizing treatment area:
1) Each anodizing process tank need 40min ,where total jig(rack)/year:​

( 2 rack x 3 tank x 60min/h) ÷40min x600 hour =5400jig(rack)

2) Design 50m²^/jig(rack) . Where every tank is 100m²
3) Area treatment/year : 5400jig(rack)x 50m² /jig =270000m²

2. Anodizing treatment weight:
Monthly output : 270000m²÷350m²/T*0.9=694T≧650T

3. Power consumption:
1) Anodising Tank:100m²/tank* 130A/ m²÷0.9=14444A/tank

Power Rectifier : 15000A =3unit
2) Clouring tank: 100㎡/tank×70A/m²÷0.9 = 7777A/tank

Colour Rectifier : 8000A =2 unit

Discription for Un

八, Composition and description of the automatic control system

1, This system is applicable to the semi-automatic production line of aluminum oxide anodization. According to its process specifications, the system is planned to adopt an upper computer monitoring and management system (composed of an industrial control computer IPC), a lower computer control execution system (PLC), detection components, and execution devices. There are two operation modes in terms of operation: manual and semi-automatic. When the system is running normally, it is semi-automatic. Based on the input of feeding data, the crane can identify the slot position in semi-automatic mode and execute corresponding oxidation, coloring and other processes. The temperature of the slot liquid meets the process requirements in semi-automatic control. In semi-automatic mode, the single step operation of the crane and related equipment can be controlled in the central control room. In manual mode, the operation can be carried out through on-site operation buttons.

2, Semi-automatic given control system
(1) The start and stop of the oxidation power supply can be controlled manually or by the PLC of the automated production line;
(2) PLC setting for oxidation working time timer or automated production line;
(3) The output current or voltage value and operation process of the power supply are set by the production line PLC and the central control system;
(4) The operating parameters and status can be transmitted to the upper PC of the production line through the communication interface;
(5) You can preset the set values according to the process and provided parameters.

九, Automatic transfer of material on the production line and transfer of material beams in the workshop
