Due to the consideration of resources and environmental protection, the use proportion of the waste steel in the steelmaking process is greatly promoted and improved at present in China.

There are problems: at present, the domestic waste steel and iron technology research has low starting point, thin foundation and low overall development level, and the recovery field is small, scattered, disordered and poor due to the particularity of waste steel products. The waste steel and iron classification and quality judgment processes have no same standard and flow which can be followed, the recycling aspect of the waste steel and iron has disordered recycled waste steel and iron raw materials, the processing technology is rough, and a plurality of new technology difficulties and problems are attached to the waste steel and iron after entering the steel-making link.

The impurity judgment of the scrap steel is also completely manual at present, and the correctness of subjective data cannot be ensured due to other factors such as severe field environment and the like. The quality of the scrap steel is checked and judged manually, the interference of human factors is large, and the contradiction is large.
