Influence of temperature and time factors on ladle inoculation effect of cast iron is investigated. It is shown that stability of inoculation effect in conditions of continuous soak is interrelated with activity of nucleating centres and character of metallurgical reactions running in time

The author presents the procedure of working out of a mathematic model of forming gas shrinkage porosity in castings of cast iron with globular graphite

In the article the new process is described of sand cores drying with binders for castings by superheat steam. It is shown that the process has many perspectives — technical, economic and ecological.

Possibilities of control over structure and properties of cast metals at different stages of casting conversion by means of dynamic bursting loading are examined.

The article is devoted to a vital problem of manufacture of cast steel grit which is widely used in foundry.

The process of computer development of casting geometrical model and engineering of mold elements is examined.

The results of investigation of thermal operation of a patenting heating furnace are introduced, including problems of mathematical simulation of heating process, scaling minimization and fuel consumption.

А mathematical model is worked out of combined problem of movement and melting of crystal and powder wire which takes into account freezing of slag envelope upon the steel envelope. Based on numerical calculation, rational conditions of treatment of wire alloys are determined

The results are presented of mathematical simulation of forming of composite ingots with different formula and properties of external and internal levels. Limit parameters of solid plug thickness are determined

А mathematical model of thermal solid plate heating in conditions of theoretical counterflow^ is worked out. The analysis is given of heating dynamics at various values of ratio of water equivalents of metal and gas.

The article gives а description of production technology of rod with different hydrocarbon content

The article introduces results of investigation of the production technology, structure, physic and mechanical properties of new mechanical doped heat-resistant alloys of special designation

On the basis of numerical simulation of heat-and- mass transfer dependencies of mass-transfer cha­racteristics of α_ϒ and  α_Ω sorption system at varying machine parameters are received. 

On the basis of numerical simulation a common choice of estimated dependencies for definition of dispersion coefficient is made. Simulation is made with account of temperature dependence of dispersion coefficient and of sorbite desorption heat. In the numerical experiment the direct-axis of mixing was not taken into account because horizontal gradients are one degree higher in devices of such type than in vertical ones.

Labour conditions of people working in foundries are examined in the article.
