Abstract:
The behavior of nonmetallic inclusions in liquid steel results from such processes as fluctuation, adhesion and collisions between particles. In the metallurgical processes that take place in the ladle, the agglomeration based on turbulent collisions between oxide particles plays the most important role. [..]

Abstract:
Production of crude steel with the help of oxygen processes will produce, according to forecasts also in the future, large portion of the world-wide steel production. In the connection with this fact the blowing systems are being further developed and improved both in case of oxygen converters, hearth furnaces and in case of electric furnaces or their combinations.

Abstract:
The most important tasks of secondary metallurgy are to accelerate the course of steel production processes and to improve its quality, at the same time limiting the amount of work, energy and sources. The basic and popularly applied treatment of secondary metallurgy is blowing the liquid steel in the ladle by inert gases. [..]

Abstract:
Current approach for microstructure images recognition and image-based properties measurement utilized manual iterative image filtering and threshold-binarization process until image areas, corresponding to desired structure elements, were extracted. This approach, however, led to information loss and inaccurate results, due to extensive filtering required to remove noise and extract features. [..]

Abstract:
The surface tension of selected real steel grades and their wetting with alumina substrate in the temperature interval from the melting point to the temperature of 1600 °C were determined using the sessile drop technique. The effect of the major elements (carbon and chromium) on the surface properties of given steels was studied. [..]
