  • Process for processing rotary tillage blade for dry farmland based on wasted steel rail
    Patent number: 11878378
    Abstract: A process for processing a rotary tillage blade for a dry farmland based a wasted steel rail is provided. The process specifically includes the following steps: selecting a waste annotated steel rail U71Mn or U75V; breaking the steel rail into a rail head, a rail web and a rail bottom in a cutting area by means of a flame cutting device and then cutting the steel rail; and applying a hydrostatic pressure to the steel rail by using a hydraulic machine to separate the rail head, the rail web and the rail bottom. The wasted steel rail can be processed into the rotary tillage blade for the dry farmland by means of methods such as segmenting, rolling, blanking, punching, electric furnace heating, bending, hot forging and thermal treatment. The surface hardness and a wear resistance value thereof are superior to those of an existing rotary tillage blade.
