Process Design and Technical Application of SED Surface Treatment Line
The surface cleaning of engineering high strength steel requires environmentally friendly process. By analyz-ing the technical performance indexes of the project and combining previous technology and engineering foundation,the steel eco descaling (SED) process for steel plate surface treatment line was designed. The key technologies such as plate smooth transportation,high-performance descaling nozzle and process parameter optimization were studied,and the problems of smooth transportation of different types of steel plates and uniformity of surface quality were solved. The production line built and put into operation can completely remove the oxidized scale skin on the surface of steel plate,and its technical indexes meet and exceed the project requirements. The application effect is obvious,which provides a new model for the construction of surface treatment line in domestic steel plants.
