Fiber laser air cutting process transformation solution

Now fiber laser cutting machine is good selling. we have many customers want to use the air cutting. So high pressure compresses air cutting process transformation solution.

1. Original reason:
Nitrogen (≦1.4MPa) mainly use for cutting stainless steel materials to ensure the stainless steel color of the cut section. Generally, the negative focus cutting is used when cutting thicker plates to obtain the best cutting effect. The best effect is to cut the stainless steel sheet. ,Good quality;
Oxygen (≦1MPa) mainly cuts carbon steel materials. And generally uses positive focus cutting when cutting thicker plates to obtain the best cutting effect;
The cutting performance of compressed air (≦0.8MPa) is poor, but the applicability is good.
Pressurized compressed air (medium and low pressure 1.4 – 1.6MPa) can cut stainless steel material. Then the cutting section is black and slightly yellow, the texture is fine. And can also cut carbon steel material, the cutting section is not much different than cutting with oxygen. But cutting The speed is a little bit more diffuse, not very obvious.
2. Pressurize compressed air cutting features: low cost, yellow cross section, large air pressure, and improve cutting capacity.

3. Advantages:

Mainly to save production costs. A single consumption of 80 kWh per day (1 yuan / KW / h), equivalent to 15 bottles (25 yuan / bottle) of oxygen working hours. Save more than 70,000 yuan / Taiwan. And can effectively improve the cutting ability and increase the cutting thickness.

4. Quality:

Compared with oxygen, the slag is slightly more and the speed is slightly longer. But the difference is not obvious. It can be distinguished by the naked eye and basically does not affect the use.
5. Negative focus cutting use regardless of the material.
6. The total investment is 75,000
7. Installation and commissioning time: 1 day

8. Process solution:

Primary compression (≧0.6MPa/2m3/h)→ storage (≧0.8MPa/2m3)→ one-time filtration→secondary filtration→first-stage drying→three-time filtratio. And then four-time filtration→secondary drying→increase Pressure treatment → Storage (≧1.4MPa/1m3)→ Flow valve→ Pipeline output. (can support 3 fiber laser cutting machines to work at the same time, cut with nitrogen process parameters, the speed adjustment can be slightly lower.)

9. Safety requirements:

The pressure resistance of each component is 2.0MPa. The safety valve: pressure relief when the pressure is MPa1.8MPa. The fixed connection of each interface. The pipeline needs to be leakproof and explosionproof.
