In particular, the replacement rate of iron and steelmaking capacities in all provinces (autonomous regions and municipalities) should be at least 1.5:1. For the corresponding capacities newly acquired as a result of mergers and reorganizations after June 1, 2021 and used for the construction of the project, the replacement rate of iron and steel production capacities in all provinces (autonomous regions and municipalities) must be at least 1.25:1.
Equivalent power replacement can be implemented in the following three cases: (1) In-house, on-site capital repairs and In reconstruction projects of iron foundry or steelmaking equipment, without changing the type, nominal capacity, quantity and location of the smelting equipment, an equivalent replacement is carried out according to the nominal capacity of the original equipment, while the capacity remains unchanged. (2) Electric steelmaking projects that use special smelting processes such as electroslag remelting, vacuum arc remelting, or vacuum induction melting to produce high-quality special steels characterized by multiple grades, small batches, and high technical content; (3) Cast iron and steel production projects built in Qinghai and Tibet.
Moreover, enterprises are encouraged to use scrap steel resources in a high-quality and efficient manner, systematically develop electric steelmaking, promote hydrogen metallurgy in regions where conditions allow, and implement environmentally friendly and low-carbon technological upgrades at existing cast iron and steel production facilities. equipment.
