High pressure compressed air cutting process transformation solution
You can check the high pressure compressed air cutting process transformation solution.
1. Original reason:
Fiber laser cutting, commonly used nitrogen, oxygen, air as auxiliary gas, because the cost of nitrogen and oxygen are higher than compressed air. And the price of nitrogen and oxygen has doubled since the beginning of 2017. Then the price of electricity Not rising.
Nitrogen (≦1.4MPa) is mainly use for cutting stainless steel materials to ensure the stainless steel color of the cut section. Generally, the negative focus cutting used when cutting thicker plates to obtain the best cutting effect. And 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, the cutting section is black and slightly yellow, the texture is fine; 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. Pressurized compressed air cutting features:
Low cost, yellow cross section, large air pressure, and improved 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 is used regardless of the material.
6. The total investment is 75,000
7. Installation and commissioning time: 1 day
8. Process solution: primary compression → storage (≧0.6MPa) → primary filtration → secondary filtration → primary drying → tertiary filtration → four filtration → secondary drying → pressurized treatment → storage (≧1.4MPa/1m3) → Flow valve → Pipeline output (can support 3 fiber laser cutting machines at the same time)
