Problems solved by technology

[0002] Low-carbon metal chromium is an important raw material for smelting special steel and ultra-low-carbon alloy structural steel. The lower its carbon content and the higher its chromium content, the higher its economic value and use value. Currently, the process of smelting low-carbon metal chromium Among them, the preparation process is long, the power consumption is high, the loss of chromium is large, time-consuming, troublesome, and material-consuming. When extracting chromium, the extraction efficiency is not high and cannot meet the needs of enterprises. Therefore, in order to solve the above problems, a new method is specially provided. Technology solutions to meet business needs
