Laser cutting machine technology innovation: new process of nitrogen cutting low carbon steel ‌

In the rapid development of the manufacturing industry, laser cutting machines have become an indispensable and important equipment in many industries with their high-precision and high-efficiency cutting capabilities. In recent years, with the continuous advancement of technology, laser cutting machines have also been constantly innovating in cutting technology. This article will introduce in detail the new process of laser cutting machines in nitrogen cutting low carbon steel, and explore its technical principles, advantages and application prospects.

1. Technical principle of nitrogen cutting low carbon steel

Nitrogen cutting low carbon steel is to use a high-power density laser beam to irradiate the workpiece, so that the material quickly melts, vaporizes and reaches the ignition point, and uses nitrogen as an auxiliary gas to blow away the molten material produced by cutting, thereby realizing the cutting process. Nitrogen plays two main roles in the cutting process: one is as a protective gas to prevent the oxygen in the air from reacting with the high-temperature molten material to affect the cutting quality; the other is as a purge gas to blow the molten material away from the cutting area in time to ensure the continuity and stability of the cutting process.

2. Advantages of nitrogen cutting of low carbon steel

Compared with traditional oxygen cutting, nitrogen cutting of low carbon steel has the following significant advantages:

‌High cutting quality‌: Nitrogen cutting has a small slit width, low surface roughness, good cutting section quality, and no subsequent grinding treatment is required, saving time and cost.

‌Wide range of application‌: Nitrogen cutting is suitable for low carbon steel materials of various thicknesses, and the cutting speed is stable and is not affected by changes in material thickness.

‌High safety‌: Nitrogen is an inert gas, which is not prone to explosion or combustion accidents, improving the safety of the cutting process.

‌Environmental protection and energy saving‌: No harmful gas emissions are generated during nitrogen cutting, which meets environmental protection requirements. At the same time, nitrogen can be recycled to reduce energy consumption.

3. New process characteristics of nitrogen cutting of low carbon steel

With the continuous development of laser cutting technology, the new process of nitrogen cutting of low carbon steel also presents the following characteristics:

‌Application of high-power lasers‌: High-power lasers can provide higher energy density, making cutting faster and more efficient. At the same time, high-power lasers can also achieve thicker material cutting.

‌Introduction of intelligent control system‌: The intelligent control system can automatically adjust the cutting parameters according to the parameters such as cutting material and thickness to achieve the best cutting effect. In addition, the intelligent control system also has functions such as fault diagnosis and remote monitoring, which improves the reliability and ease of use of the equipment.

‌Optimization of nitrogen supply system‌: The nitrogen supply system adopts efficient and energy-saving nitrogen generators and gas tanks to ensure the stability and continuity of nitrogen supply. At the same time, the nitrogen supply system also has automatic detection and alarm functions to timely detect and deal with problems in nitrogen supply.

4. Application prospects of nitrogen cutting of low carbon steel

The new process of nitrogen cutting of low carbon steel has broad application prospects in the manufacturing industry. For example, in the automotive manufacturing industry, nitrogen cutting can be used for cutting and opening of body panels; in the aerospace field, nitrogen cutting can be used for cutting of aircraft skins, frames and other parts; in the shipbuilding industry, nitrogen cutting can be used for cutting of hull structural parts, etc. In addition, with the rapid development of new energy, new materials and other industries, the new process of nitrogen cutting of low carbon steel will also be applied and promoted in more fields.
