Pure iron for charge, also known as pure raw material iron or pure iron for smelting, is represented by Chinese pinyin capital letters and Arabic numerals. According to the different composition, pure iron for charge is mainly divided into the following types:
YT0: The iron content is above 99.8%, and the carbon, phosphorus and sulfur content are low, which is suitable for various smelting needs.
YT01: The iron content is above 99.9%, and the carbon, phosphorus and sulfur content are lower. It is the best pure iron for smelting and is suitable for high-demand smelting processes.
In addition, the chemical composition of pure iron for furnace charge usually includes:
Carbon (C) ≤ 0.002%
Silicon (Si) ≤ 0.005%
Manganese (Mn) ≤ 0.02%
Phosphorus (P) ≤ 0.005%
Sulfur (S) ≤ 0.003%
Aluminum (Al) 0.004%
Titanium (Ti) ≤ 0.002%
Chromium (Cr) ≤ 0.010%
Nickel (Ni) ≤ 0.01%
Copper (Cu) ≤ 0.01%
Oxygen (O) ≤ 0.01%
Nitrogen (N) ≤ 0.004%23.
Pure iron for furnace charge has a wide range of uses, mainly used in:
NdFeB, permanent magnet materials, amorphous alloys, electrical alloys, precision alloys, stainless steel furnace charge and other industries.
