Technological basis of obtaining of the big-sized cast-welded bimetallic
constructions
The optimal temperature-and-time parameters of casting, regimes of welding and heat treatment by production of cast-welded bimetallic constructions of the big-sized parts of machines and equipment operating in the conditions of the intensive wear are presented. The results of experimental-industrial tests of the cast-welded bimetallic constructions of the reversible impact beaters of rotary crushers are given. It is shown that technical resource of such constructions increases in 3-4 times the resource of the monometallic beaters of manganese steels. The recommendations on cast-welded bimetallic constructions in industry are formulated.

The Inoculation Sand Blends Prepare Casting with Superalloys Melts
The inoculation by disperse powder of B, Al, Si, Ti and their mixtures are proposed for running ability level increase of casting molds, rods, and fluxes. The bulk-thermal parameter (P - parameter), which correlate with bulk effect and enthalpy of compounds formation are proposed, for determination of mechanism behavior chemical reactions in time of inoculation. P-parameter allows to determinate the chain of several chemical compounds formation.
