Study on Cutting Process of Manual SHS Cutting Technology
Cutting process of manual self-propagating high-temperature synthesis (SHS) cutting technology was studied based on industrial Q235 steel specimen and cut material of cutting pen. Through research of kerf and analysis of manual SHS cutting process, three zones of base metal is formed under the cutting pen process: molten zone heated directly by cutting pen, the common active zone of cutting pen , metal flow and slag flow, metal flow and slag flow heating zone. Its cutting process can be divided into four inter-related stages as follows: the formation stage of the molten pool, the increasing stage of the pool penetration, the stage of slag blowing off and kerf formation and then the formation stage of a new pool. The way to improve efficiency of manual SHS cutting technology is proposed at the end.
