Outotec's open slag bath smelting furnace is a closed furnace that offers high productivity and efficiency in a sustainable way. It is robust, safe, and easy to operate. The furnace is custom designed for each individual application and the optimized furnace and feed system layout makes it a highly cost-efficient solution.
- Raw material is reduced at high temperature with carbon reductant such as anthracite or coke
- Alloy sinks to the bottom and slag floats to the top – these are tapped intermittently through dedicated tap holes
- Off-gas, mainly carbon monoxide, is cleaned and can be reused as combustible fuel
