Application: Metal Smelting
In the metal smelting industry, from the high-temperature melting of ores, refining and purification of metals to the casting of finished products, each link has extremely high requirements for the stability, continuity and cleanliness of compressed air. Whether it is to drive the pneumatic equipment to clean the furnace, adjust the gas flow in the smelting process, or provide power for the dust removal system, a stable and reliable air source is the key to ensure the quality of smelting, improve production efficiency and reduce energy consumption. ZAKF, a brand of Dongguan Jubei Compressor Fittings Co., Ltd, has launched 175HP frequency
Screw Air Compressor, which has become an important equipment for metal smelting enterprises to enhance their competitiveness by virtue of its high reliability, long service life and stable and efficient performance.
A large-scale metal smelting enterprise located in Western Australia, Australia, is mainly engaged in iron ore smelting and refining of copper, aluminum and other metals. Before the introduction of ZAKF 175HP frequency
Screw Compressor, the air compressor used by the enterprise was characterized by large fluctuation of air pressure and high equipment failure rate, which led to unstable gas flow control during the smelting process, and the purity of some batches of metal was not up to the standard, and the rate of product rejects was as high as 15%. At the same time, frequent equipment failures led to a monthly downtime of up to 22 hours for maintenance, which cost up to 200,000 Australian dollars per year, and energy consumption remained high, seriously affecting the economic efficiency of the enterprise. Mr. Williams, the production manager, said, “The unstable gas supply and high operating costs were causing us to lose our competitive edge in the market, and we urgently needed to find a reliable solution.”
With the ZAKF 175HP IF screw compressor in operation, Barton Metalworks' production has improved significantly. The direct-drive design of the IF motor and the precision meshing of the twin-screw rotors maintain a stable discharge rate of 20m³/min (0.9MPa), which provides stable power for the smelting process and reduces the scrap rate to 5%. The cast iron body and forced lubrication system, together with the long-life bearings, ensure the stable operation of the core components, and the maintenance cycle has been extended to 6,000 hours, which reduces the downtime for maintenance by 90% and saves more than AUD 180,000 per year in maintenance costs. In addition, compared to the previous piston machine, this model saves 35% of energy when running at full load and reduces the annual electricity bill by about AUD120,000 per year. Mr. Williams is excited to share, "The
Fixed Speed Air Compressor is very stable in operation, and the noise level is controlled at around 75dB, which is virtually unaffected even in the noisy smelting workshop. The three-stage filtration system ensures the cleanliness of the compressed air, and now our productivity has increased by 50%, our product quality is more stable, and we are more competitive in the international metal market!"
In addition to its excellent performance, the ZAKF 175HP frequency screw compressor's simple and durable structural design reduces maintenance costs by more than 30% compared to frequency converter models, and its IP54 protection rating and wide temperature range of -15℃~45℃ make it easy to cope with the high-temperature and dusty environment of metal smelting workshops. Dongguan JOBE Compressor Parts Co., Ltd. provides global after-sales service, including one-year warranty, sufficient stock of overseas original spare parts, as well as a team of professional engineers to quickly respond to the needs of installation and commissioning, regular maintenance and fault repairs for the stable production of metal smelting enterprises.
