STEEL MATERIAL QUALITY DETERMINATION DEVICE AND STEEL MATERIAL QUALITY DETERMINATION METHOD

摘要

It is an object of the invention to determine the type of steel, can stably and accurately whether be made of the low-alloy steel of carbon steel or steel of the judgement. There is provided a kind of for measuring the type of steel, including image pick-up device 11 produced and ground in steel 18 for spark to be imaged, continuous several times; Detection device 12 corresponds to the spark polishing alloying component that alloy generates and passes through image pick-up device from the imaging of each shooting image 2 in steel for detecting alloy spark location; Computing device 13, for calculate spark location sum in alloy by the detection device; Steel are determined by low-alloy steel with judgment means 14, if total number is not less than first threshold, determining and steel are by carbon steel, if total quantity is less than first threshold.
