81-83 3541
Abstract

It is shown that mechanical and metallographic characteristics of rod, rolled at speed 100 and 105 m/sec, correspond to ZTU 840-03-2006.

84-88 408
Abstract
The possible reasons of nodular cement formation in structure of wire-slug for production of metal cord and wire RVD are determined and systematized
89-91 367
Abstract

It is shown that steels microalloyed with chrome can be used in production for making of super- and ultra-high-strength wire.

92-98 1777
Abstract

It is determined that maximal diameter of the wire at drawing through one and the same die corresponds to size of unit squeezing 0,5-1,0%.

99-105 400
Abstract

The methods of influence on quality of uninterruptedlycasted slug from the point of  view of  the axial chemical heterogeneity depression are considered, at the same time high emphasis is placed on use of  soft squeezing method.

106-114 403
Abstract

Analytical method is developed and calculations of temperature and thermostressed state at hardening of continuously-casted slab slugs at high-level cooling are carried out on the basis of the equivalent sources method.

115-121 416
Abstract

The method of calculation of the main technological parameters of the remelt: current intensity and diameter of consumable electrode is developed on the basis of mathematical modeling.

Computer-aided design of foundry production

122-130 1865
Abstract

Optimization mathematical models of evolution of the steel details chemical-thermal treatment are developed. Numerical modeling of  distribution for carbon in the surface layers of the object is carried out.

131-139 448
Abstract

The data of modeling on supercomputer system SKIF of technological process of  molds filling by means of computer system 'ProLIT-lc', and also data of modeling of the steel pouring process by means ofTroNRS-lc'are presented. The influence of number of  processors of  multinuclear computer system SKIF on acceleration and time of  modeling of technological processes, connected with production of castings and slugs, is shown.

148-154 386
Abstract

Prospects of  the method of directional- successive crystallization at production of shaped castings of  cast irons of different grades are shown.

155-161 3665
Abstract

Prospects of technology Cold-box-amin for mass production of cores by computer approach in all spheres of machine-building are shown.

162-165 381
Abstract

Nonstick covering KDD-S, which is used for production of steel and cast iron castings, is developed.

166-170 394
Abstract

Use of electroslag crucible remelting with accumulation of  liquid metal allows to reduce considerably the requirements to accuracy of keeping up of electric parameters and in that way to provide possibility of use of  consumable electrodes.

171-174 1902
Abstract

Estimation of ecological safety of melting processes and out-of-furnace processing of aluminium alloys is given.

175-181 392
Abstract

The ways and means of fibre-optic and optic-electronic thermoscopy in casting and metallurgy are examined.

182-187 364
Abstract
The ways of levelmetry and their realization are studied on the basis of mechanical, electromechanical, die, optical and light-guiding transformers of linear and angular coordinates are examined.
