1. Technological breakthrough
The core of NEWTEK 99% high-purity oxygen production equipment is that it uses pressure swing adsorption (PSA) technology to efficiently separate compressed air through zeolite molecular sieves to produce oxygen with a purity of up to 99%. Compared with the industrial oxygen used in traditional cutting (purity of about 93%), high-purity oxygen significantly improves combustion efficiency:
Cutting speed improvement: For every 1% increase in oxygen purity, the cutting speed can be increased by about 1.5%. In the cutting of 30mm carbon steel, the measured speed of NEWTEK equipment reached 1100mm/min, which is more than 30% higher than the traditional process.
Optimized slit quality: high-purity oxygen combustion is more concentrated, the slit width is reduced from 3-4mm in the traditional process to less than 1.5mm, and the cross-section flatness error is less than 0.1mm.
Energy consumption and cost reduction: Due to the improved combustion efficiency, the oxygen consumption is reduced by 20%, and no additional slag removal is required after cutting, and the overall cost is reduced by 15%.
2. Actual application cases
1. Measured data of the cutting process
During the test, NEWTEK equipment continuously cuts 30mm Q345R steel plates:
Cutting speed: 1100mm/min (traditional process about 850mm/min);
Slit width: 1.2mm (traditional process about 3.5mm);
Cross-section quality: no slag, surface roughness Ra≤12.5μm;
Oxygen consumption: oxygen consumption per square meter 18m³ (traditional process about 22m³).
2. Challenges of complex workpieces
When cutting 30mm carbon steel with grooves, NEWTEK equipment uses an intelligent oxygen pressure regulation system to achieve one-time forming of Y-type and X-type grooves with an accuracy error of less than 0.3mm. A bridge manufacturing company reported that after using this equipment, the groove processing time was shortened from 45 minutes in the traditional process to 20 minutes.
3. Environmental protection and safety
The amount of waste gas generated by high-purity oxygen combustion is reduced by 40%, and the equipment is equipped with an automatic exhaust system for unqualified oxygen to ensure that the entire cutting process meets environmental protection standards.
3. Market response
1. Cooperation case of leading enterprises
A scrapped car processing plant: After introducing NEWTEK equipment, the average daily cutting capacity increased from 50 tons to 70 tons, and the labor cost was reduced by 30%.
A steel structure engineering company: In the batch processing of 30mm thick steel plates, the equipment ran continuously for 72 hours without failure, and the cutting qualification rate reached 99.8%.
4. Industry impact
1. Technical standard upgrade
NEWTEK's breakthrough prompted the industry to redefine the thick plate cutting standard. The China Metal Processing Association has included high-purity oxygen cutting in the "2025 Metal Processing Technology White Paper", and explicitly recommends 99% pure oxygen as the preferred solution for thick plate cutting.
2. Synergy effect of the industrial chain
Upstream steel mills: began to give priority to the supply of extra-thick steel plates (such as Q355D, Q345R) suitable for high-purity oxygen cutting.
Downstream applications: In the fields of shipbuilding, wind power equipment, etc., the application rate of high-purity oxygen cutting technology increased by 45% year-on-year.
