PRESENTATION

Foundry

26-29 236
Abstract

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

30-31 1792
Abstract

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

32-37 251
Abstract

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.

38-41 1540
Abstract

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

42-44 215
Abstract

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

CAD foundry

45-49 1334
Abstract

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

Metallurgy

50-54 1563
Abstract

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.

55-59 246
Abstract

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

60-62 236
Abstract

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

63-64 257
Abstract

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.

65-75 252
Abstract

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

76-82 281
Abstract

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

Ecology

83-85 228
Abstract

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

86-89 227
Abstract

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.

Protection of labour

90-95 236
Abstract

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