DETECTION METHOD OF SURFACE SIGNS OF METALLURGICAL ITEMS, PARTICULARLY INGOTS OBTAINED BY CONTINUOUS POURING, AND ROLLED ITEMS, AS WELL AS DEVICE FOR METHOD'S IMPLEMENTATION Russian patent published in 2013 - IPC G01N21/88 

FIELD: metallurgy.

SUBSTANCE: in the method for detection of surface signs of metallurgical items, particularly of ingots obtained by continuous pouring, or rolled items, a certain fragment of surface (12, 12') of the item is irradiated at least from two radiation sources of various wave length from different directions, and the irradiated fragment of the surface is fixed by means of optoelectronics. Three light sources (21, 22,) located in three planes (E₁, E₂, E₃,) forming an angle of 120 between each other and perpendicular to the item surface (12, 12') are directed to surface (12, 12') of the item at equal angle (α).

EFFECT: it is possible to obtain and record useful information on metallurgical items during a very short period of time so that they can be identified without any errors and the surface state and structure can be determined as well.
