It is shown that thermal-convection melt flows, arising in liquid costing pipe as a result of melt spray effect and acting along the front of ctystallization, have a great influence on forming of hard encrust right up to its fusion. The degree of this influence depends on the character of allocation and intension of thermal-convective flows. 

The article describes technological peculiarities of production of continuously-cast ingots by continuous horizontal method of casting into benched crystallizer.

Mechanisms of modification of cast iron and steel\^ were analyzed and thermodinamic performance criterion of modifiers was defined. It is shown that in cast irons, Mg, Ca and P3M mostly act like refining modifiers. In steel they act as refining and surfactant species. Effectiveness of modifiers for steel is determined by their high degassing and surface activity, low distribution coefficient, weak interaction with Ъ-Ре, low activity in liquid metal.
