The analysis of ranges of possible change of temporary resistance of sB of castings from ductile and gray cast iron is carried out. The analytical description of ranges of change of sВ depending on casting BH hardness is developed. It is shown that the range of change of sВ of pig-iron castings, wider in comparison with steel, with the measured hardness of BH is caused variations of forms and the amount of graphite inclusions at the considered classes of cast iron and influence of thickness of a wall of casting from gray cast iron on dependence of sВ (HB). The result is intended for determination of the guaranteed casting size sВ without her destruction, when there is no information on sВ of check test pieces.

The increase in operational durability of the technological tools of the piercing mill in the pipe-rolling shop and decrease in deficiency of produced pipes due to improvement of calibration of cone-shaped rolls is considered in the article.

It was established that the cause of formation of non martensitic transformations of austenite in carburized cases and in a core of workpieces is insufficient cooling capacity of the hardening module of a vacuum line «ModulTherm 7/1».

Based on the analysis of the known methods of separation of the bar stock into cut-to-length sections, it has been found that the most effective is the process of transverse screw rolling with the preliminary application of a ring-shaped wedge-shaped groove to the bar. In order to reduce its depth, it is proposed during the rolling process to displace the separated part of the material in a plane perpendicular to the axis of the rod by the amount of plastic crushing characteristic for the stamp cutting of the assortment.

The calculations of the magnetic field induction and the magnetic field intensity were carried out by the Finite Element Method (FEM) with the use of the software FEMM. The cylindrical inductor of the Magnetic-Pulse Installation (MPI) generates the magnetic field near the surface of the cylindrical steel product as of the uniform as well as variable cross section. It is shown that the regions of the products of the complex cross-section located at the minimal distance to the helix inductor are exposed to highest level of hardening. It is necessary to increase the current pulse in the inductor or to use a split inductor with the variable inner diameter repeating the product profile for hardening of the product regions located at large distances from inductor. The side surfaces of protrusions that are perpendicular to the axis of the system are not exposed to hardening due to the low gradient of the energy density of magnetic field near its surface. In the case of close proximity of the protrusions (for distance less than 1 cm), the material on the product surface in the space between protrusions is not exposedto sufficient hardening.

It was shown that increase of hardening level in comparison with the required index has not been achieved.
