SMS group has added special features that not only improve process efficiency and vessel availability but also guarantee a longer converter life:

• Improved lining in the tuyere zone, mouth, and off-gas offtake areas
• Supersonic injection tuyeres with higher oxygen levels, generating less off-gas for smaller gas treatment plants
• Prolonged refractory lifetime
• Optimized automation with BlueControl

The supersonic injection system represents a significant improvement for Peirce-Smith converters and allows a deeper penetration of the bath with finer bubbles. This enhances the gas/liquid interface and with it the metallurgical reactions. This means that shorter tap-to-tap times, lower gas consumption, and a longer lining service life are achieved.

Hamburg-based Aurubis AG successfully installed new converters in 2019, which were supplied by SMS group and are used to produce blister copper, in order to strengthen and consolidate its global position as an integrated copper group and one of the world’s largest copper recyclers. With regard to planning, SMS group utilized 4D engineering, linking the 3D design with a detailed time schedule for the dismantling of the existing converters and the erection of the new ones. Our experts coordinated the transportation to the company’s site.
