Steel Production - American Iron and Steel Institute

The use of EAFs has expanded and now accounts for nearly 2/3 of steel production in the United States. The EAF is different from the blast furnace as it produces steel by using an electrical current to melt scrap steel and/or direct reduced iron. The EAF uses scrap steel and electricity to produce molten steel.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
