6 FAQs about [How Solar Steelmaking Technology Works]
Can solar energy power the steelmaking process?
In this paper, the EAF steelmaking processes driven by solar energy system (EAF-SES) was developed, which supplies electricity for the whole process, and reduce the dependence on traditional energy sources.
Do solar energy systems match EAF steel making processes?
Furthermore, there is still a lack of consideration of the design parameters and performance characteristics of the solar energy system matching the described EAF steel making processes, which wish to be identified in the subsequent research. The typical EAF-SES under the HM ratio of 50% was presented and explored.
How is solar energy used in EAF steelmaking?
Solar energy first generates electricity. This part of electricity is directly used in EAF steelmaking processes by electrical equipment. In addition, the remaining electricity is adopted for thermal energy, such as producing steam or preheating the furnace charge.
What is the process of steel production?
The process of steel production derives from two main routes. Electric arc furnace steelmaking (EAF) process is one of the ways to produce steel (Yang et al., 2021).
Why was solar energy not used in smelting system?
This was mainly due to the large amount of HM and typical carbon containing materials, such as anthracite, metallurgical coke, carbon powder, etc. These materials were not replaced in the existing steel production system. In IMU and STU, solar energy could not be directly used to provide heat energy for smelting system.
