Algorithm of Mathematical Processing of Information Obtained from the Surface of Steel Samples at the Study of Pollution of Steel by Non-Metallic inclusions

Abstract

In the process of steel smelting, nonmetallic inclusions are formed, which impair steel quality. To determine their numbers and sizes, polished planes are made from a sample of finished steel, on which only the inclusion cross sections can be seen, and not the inclusions themselves. According to currently accepted methods in metallurgy, information taken from the surface of polished planes is not efficiently processed. The paper proposes a method based on the theory of probability and mathematical statistics for the mathematical processing of information on inclusion sections for determining the quantities and sizes of the inclusions themselves in the volume of a metal. The algorithm of calculation is given. The method was tested, which showed the suitability of the algorithm.
