Green Design of A Descaling Machine for Remanufacturing Cleaning Based on QFDE

The importance of the reuse of steel plates is highlighted, because of the intensifying pressure of recession and natural resource shortages. The surface rust of steel plates is removed by a remanufacturing cleaning process so that they can be reused, which in turn reduces steel waste and saves costs. However, the remanufacturing cleaning process has disadvantages such as high-labor intensity, high-energy consumption, and high pollution. Therefore, it is necessary to design a descaling machine for remanufacturing cleaning with high efficiency, low pollution, and good cleaning and rust removal effect. Firstly, quality function deployment for the environment (QFDE) is used to obtain the functional characteristics that the designer needs to focus on, and a better structural scheme is obtained by constructing the functional structure expansion solution domain. The design of a descaling machine is a win-win for both customers and manufacturers.
