As the metallurgical industry in Europe, America and South Korea transitions towards low-carbonization and high efficiency, high-purity oxygen supply equipment has become a core support for improving smelting quality. Recently, the psa based oxygen plant customized by GNEE specifically for the metallurgical field has completed mass production. A total of 10 units are being shipped in two batches to large metallurgical enterprises in Pohang (South Korea), Dortmund (Germany) and Pittsburgh (USA), for use in stainless steel smelting and special steel production processes. As a manufacturer deeply engaged in psa technology for oxygen generation (PSA Oxygen Generation Technology), the exported equipment has not only obtained EU CE certification and Germany's TÜV Rheinland certification but also complies with American Welding Society (AWS) standards, becoming a core equipment for the upgrading and transformation of overseas metallurgical enterprises.
The oxygen-blown smelting process in the metallurgical industry has extremely high requirements for oxygen purity and stability. For every 1% increase in oxygen purity, the molten steel smelting time can be shortened by 8%, while energy consumption can be reduced by 12%. The exported pressure swing adsorption oxygen generator adopts modified lithium-based molecular sieves and multi-tower adsorption technology, enabling stable output of industrial oxygen with a purity of 99.5% and impurity content controlled below 0.005 ppm, which fully meets the strict requirements for gas purity in special steel smelting. The single-unit oxygen output of the equipment covers multiple specifications from 200 to 800 Nm³/h. Among them, the large-scale equipment customized for Pohang, South Korea, has an oxygen output of 800 Nm³/h, with a unit oxygen power consumption of only 0.32 kW·h/m³, which is 22% more energy-efficient than the local original equipment. "Traditional oxygen generation equipment not only has high energy consumption but also often affects the composition of molten steel due to pressure fluctuations," said the production director of a German metallurgical enterprise. "This psa oxygen plant is equipped with an intelligent pressure compensation system, which controls the oxygen supply fluctuation within ±0.3%. After commissioning, the qualified rate of our special steel has increased from 92% to 98.5%, bringing an additional monthly benefit of over 500,000 euros."
To adapt to the complex working conditions of high temperature and heavy dust in metallurgical workshops, the equipment adopts a fully enclosed corrosion-resistant shell and high-temperature resistant pipeline design, which can operate stably in an environment of -10℃ to 50℃. In addition, GNEE provides customized training services for customers, combining online theoretical teaching with offline practical guidance to help operators quickly master equipment commissioning and daily maintenance skills. "The service response speed of Chinese manufacturers exceeds expectations. During the equipment installation and commissioning period, the technical team provided 24/7 on-site support, ensuring the seamless connection of our production lines," commented the American buyer's representative in the acceptance report. The bulk export of this special oxygen generation equipment for the metallurgical industry not only demonstrates China's technological breakthrough in psa oxygen plant process but also provides cost-effective Chinese solutions for the green transformation of overseas high-energy-consuming industries.
