Abstract
A technique is developed and an X-ray TV study is performed to investigate the penetration of spherical tin samples into the steel 40Kh melt at a temperature of 1550°C. Cold spherical tin particles 1–2 in weight are found to dissolve in the tin-free steel at an initial rate of 180 ± 50 mol/(m2 s). A sample dissolves fully in less than 2 s. When a sample reaches the steel–gas phase interface, its dissolution rate decreases by many times. Separation with the formation of a two-phase system occurs at 1.6–1.9 mol % tin in steel. The density of the iron-based alloy is lower than that of the tin-based alloy. Pure tin and the saturated solution of iron in tin wet Al2O3-based refractory ceramic better than pure iron or its alloy with tin.
