Abstract

The present project has been carried out to optimise the Consteel-EAF system and to demonstrate the benefits of this innovative technology. The objectives of the project are:
- to design and apply optimised operating practices of the process, permitting the carrying out of the process with minimum electrical energy consumption for different amounts of coal used;
- to identify and solve environmental problems, if any, connected to the possible release of polluting emissions through gases and fumes resulting from scrap heating.

The works comprise:
- development of mathematical models of scrap pre-heating in the tunnel and an EAF process to design operating practices of the whole operations scrap pre-heating and EAF steelmaking;
- experimental trials to tune the models;
- design on the basis of model, testing and validation in long period trials of optimised operating conditions, permitting the carrying out of the process with different amounts of coal to generate chemical energy.

Main results were:
- definition of new operating practices, for the EAF-Consteel process characterised by different ratios of chemical to electrical energy used in the process;
- decrease of electrical consumption for EAF operation through proper management of post-combustion in both the tunnel and EAF;
- maximum recovery of energy from scrap pre-heating;
- low level of polluting emission from the plant still with the new designed practices.
