What is the steel quality of Yunnan Phoenix Iron and Steel Co., Ltd.? Why do you say it is good to become steel, not Fenggang?

Mainly the refining process after iron and steel smelting. Large steel mills, especially state-owned enterprises, carry out different refining treatments according to different steel grades to remove impurities and harmful gases, which are omitted by private small factories in order to reduce costs. In the rolling process, the continuous rolling mill of state-owned big factory has large installed power, many rolling passes, large reduction rate and controlled cooling, which makes the crystal phase structure of steel compact and the properties of steel good. In order to reduce costs, small private enterprises have adopted the ellipsis process. Of course, there are still some factors for the poor materials, so I won't elaborate on them one by one.
