Thyssenkrupp Steel Europe ordered from Danieli Centro Combustion the delivery of two new complete walking beam furnaces for heating steel slabs at a hot rolling mill located in Duisburg.
The project is part of Thyssenkrupp's 2030 strategy and slab reheat furnaces are scheduled to start up in early 2024.
The new walking beam furnace will provide high productivity while reducing energy consumption, reducing gas emissions and improving the surface quality of the slabs.
Danieli said that with capacities of 380 tonnes per hour when cold loaded, up to 560 tonnes per hour when hot charged, the design and performance of the furnace will be based on maximizing energy efficiency, fuel consumption and reducing emissions.
Optimization of the combustion system, which is designed for the possible addition of hydrogen up to 48% by volume (maximum hydrogen content in the mixture is about 66%), will lead to an increase in the efficiency of the furnace and a decrease in CO 2 emissions to about 53 kg per ton of steel with continuous operation at maximum load.
