Abstract
Measured the viscosity of liquid steels 32Г1 and 32Г2. Samples taken from the pipe Naftogaz assortment. Measured temperature and time dependences of the kinematic viscosity of the liquid steel 32Г1 and 32Г2. The viscosity of the liquid steel is measured by means of damping torsional oscillations of a crucible with melt in heating and subsequent cooling in the range 1450–1810°C. Results viscometric experiment discussed in the framework of modern concepts of micro heterogeneous structure of metallic melts. Recommendations optimal regime of temperature-time processing of liquid steel 32G1 and 32G2 authors eventually made. It is shown that for steel 32G2 appropriate to raise the temperature of heating the melt to 1650–1670 ° C, i.e. apply a temperature-time processing.
