It is shown that research of scaling on the uninterruptedly-casted and the hot-rolled blanks, enabling to improve quality of production and due to that to increase its competitiveness, is actual

Peculiarities of formation and distribution of pearlitic structure of steel 80K in a blank and after deformation in various areas of wire mill (in semi-finished rolled products and rolled wire) are established. It is shown that irregularity of temperature field by the section of semi-finished rolled products influences on processes of structure formation. It is shown by researches that the increase of deformation degree and the subsequent controlled accelerated cooling in the line of wire mill 150 leads to increase in uniformity of pearlitic structure and its dispersion.

It is shown that after thermo-mechanical processing of chrome-molybdenic rolled metal including cooling with a speed of 0,6-0,8 ° C / sec, the quantity of bainite increases to 75% and the amount of lamellar pearlite decreases to 5-10% in structure that promotes reduction of the mode of subsequent softening processing. It is established that at cooling with a specified speed the transformations in chrome-molybdenic steel come to an end at temperatures of 350-370 ° C. The offered technology of the reduced mode of thermomechanical processing provides necessary quality of rolled metal and promotes decrease of energy resources consumption.

As a result of analytical and experimental studies of processes of the high-carbonaceous brass-plated wire twist the dependence allowing to estimate fully the influence of twist conditions on metal cord breakage is defined.

The whole technological process of the high-quality seamless pipes production on the pipe-rolling unit of JSC “BMZ” is considered.
