NOUFERROUS METALLURGICAL EQUIPMENT

In 2015, the green-field upgrade project for Henan Zhongyuan gold smelter was put into operation. The project is designed for handling 1500000 tpa copper concentrate containing precious metals, and it is scheduled for 2 stages. The project process employs oxygen bottom blowing furnace as smelting, Rotation-Suspension furnace as converting, and rotary anode furnace as refining. Wherein, the Rotation-Suspension furnace with reaction shaft size Φ4.5m×6.2m named from the use of the Yanggu patented Rotation-Suspension nozzle, is entirely innovative designed by ENFI under Yanggu’s progress package. Rotation-Suspension converting furnace is an innovative design of a metallurgical furnace after comprehensive summary of decades of experience in the design of large metallurgical furnace. Besides this, it is also the first domestic converting furnace using domestic technology, completely independent design, all domestic manufacturing Rotation-Suspension converting furnace, with a reasonable structure, compact layout, easy operation, low maintenance, high rate of operation, etc. Applying advanced overall flexible frame structure and rational water-cooling technology, coupled with matching brick, fully adapted to Rotation-Suspension process, the converting furnace has the technical characteristics of safe, stable and efficient, long life. After 5 years of excellent operation, it can come to the conclusion that the design of Rotation-Suspension is supper successful.
