Thermophysical properties measurement of scale layer on steel substrate using flash method

Popis výsledku v původním jazyce

Most of the steel is processed at very high temperature. The hot steel surface is in contact with surrounding atmosphere and reacts with oxygen which is contained in it. Ferrite oxides are formed on surface. These oxides are called scales. Scales form very complex layer on the surface. Sales are mostly porous and composed of various scales such as Wüstit (FeO), Hematite (Fe2O3) and Magnetite (Fe3O4). Steel grades contain various additives, and one of the most common is silicon, which forms Fe2SiO4 (fayalite). Other additives such as aluminum, chrome, nickel, molybdenum form even more complex scales. Although scales form relatively thin layer on the surface it was confirmed that they need to be included in simulations of steel heat treatment as they can significantly change cooling rate due to the Leidenfrost effect during spray water cooling. Only a limited number of publications describing the thermophysical properties of scales can be found. Mainly due to various porosity of scales, which significan
