【 摘 要 】

This paper analysis one of the basic properties of liquid slag which is viscosity. The slag in the mold fills there is between the wall and the ingot mold, where it occurs in the form of a thin layer of solidified and molten slag. The main function is to lubricate the walls of the crystallizer and control of the heat transport from the solidifying steel. The research work carried out by concentric cylinder viscosity for five samples of slag for use in industrial environments. The study was conducted for the temperature range 1200-1550°C. Then the experimental results were compared with model calculations. The differences between the experimental results and the model calculations are related to the construction of the slag and the assumptions. Measurements under laboratory conditions on the two-phase system: a liquid solution of the dispersed phase ion steel - carbon, whereas the calculation model are the liquid-phase, and therefore the viscosity calculated values are lower than the values measured.
