Abstract
An automatic steel analysis apparatus for analyzing the composition of steel materials by carrying out an element analysis using an X-ray excited energy dispersion type fluorescent analysis in the conveying path of the steel materials. A movable housing is vertically movably mounted below the conveying path and has a window in the top thereof closed by an X-ray permeable membrane. An X-ray tube and a semiconductor detection element are housed in the movable housing, and the detection element is connected to a computing apparatus for supplying analysis information thereto for enabling the computing apparatus to determine the composition of steel materials. An air conditioning apparatus controls the temperature and humidity within the movable housing. A leaded rubber packing is mounted around the outside of the window for engaging with the under side of the steel material located in the conveying path when said housing is raised, and an openable and closable protective shutter is mounted on the housing and movable between a position in which it covers said window to protect the X-ray permeable membrane and a position away from the window and in which the window is uncovered. A sensor connected with the leaded rubber packing senses the engagement of the leaded rubber packing with the under side of a steel material, and an X-ray shutter opens to expose the X-ray tube for a predetermined time sufficient for carrying out analysis in response to the sensing by the sensor of the engagement of the leaded rubber packing with a steel material.
