THEORETICAL PREREQUISITES OF RECEIVING OF QUALITATIVE METAL PRODUCTION IN PIPE ROLLING

The theoretical suppositions for creation of qualitative metal production in pipe rolling, based on the principles of production of defect less slug on the continuous casting machines, are worked out

Using of the simplified solutions of the problem of Stefan at designing of ray auxiliaries

In the article there is examined the problem of application of the conformal maps method at the projection of the foundry processes auxiliaries. There is given the solution of the problem of Stefan for more typical configurations of design field at projection of discard heads and outside chiller

INDICES OF ELASTICITY OF THE CARBON AND ALLOYED STEEL AT HIGH TEMPERATURES (REVIEW)

The information given in technical literature on the matters of embrittlement of different types of steel close to temperature of solidus and in a range of structural inversions in the system of granules austenite is examined. The received information is supposed to be used at the following calculated evaluation of the admissible regimes of cooling and heating of slugs under terms of uniformity preservation

PROCESSES OF MASS-TRANSFER IN DENDRITE GRIT AT HARDENING OF STEEL INGOTS AND SLUGS

The processes of mass transfer in dendritic grid of hardening steel ingots and continuously cast slugs are investigated using the mathematical modeling taking into account separation diffusion in two-phase zone and inflow of melt into the shrinkage zone. The regularities of the additives (by the example of carbon and sulfur) allocation are determined
