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.

Abstract: A method for cutting side plates and end plates of a scrapped railway boxcar aims to improve low disassembling efficiency as it is difficult to disassemble the scrapped railway boxcar. The steps of cutting the side plates includes: A1: cutting a top of an upper side plate; A2: performing cutting downwards, dividing the upper side plate, and then cutting the left upper side plate; A3: cutting the right upper side plate; A4: cutting a lower side plate; A5: cutting off upper channel steel on columns; A6: cutting off lower channel steel on the columns; and A7: cutting the columns. The method avoids complicated working conditions of directly cutting angle iron, the channel steel, multilayer boards and closed regions, so that the cutting efficiency of the side plates and the end plates of the boxcars is improved. Moreover, automatic cutting can be realized according to a set cutting path.
