The SCR catalyst that has just been extruded is soft in texture and easily deformed under great pressure. It is also necessary to ensure that the robotic arm fully fits the SCR catalyst to avoid excessive local pressure. Existing robotic arms are difficult to meet special needs and need to be modified.
