Bases of theory of creation technological systems recovery of large products in heavy engineering

There has been considered a pressing theoretical and practical issue of up-to-date engineering, concerning the development of resource-saving technology in heavy engineering, based on large products recovery. It is known, that in spite of long operational life of large products, after expiration of their operational life in regards to working surface and their subsequent retirement, they still have significant residual operation time as for load cycle and fatigue stresses with high figures of overall geometrical dimensions and parameters. Theoretical investigations of large compound/sleeved products life cycle, given through the example of mill rolls, allowed to suggest scientifically-grounded aspects for creation of technological recovery systems for such products in heavy engineering. On the basis of theoretical and experimental investigation results analysis of these systems, which include operations of compound products dismantling by thermal action, deformation of reused parts followed by assembling, the principles of their development during large products recovery have been substantiated. Developed technological systems for large products recovery have been introduced in heavy engineering followed by succubus application, in particular, regarding sleeved backup rolls recovery at some leading enterprises of Russia and Ukraine.

Modifying Additives to Electrolytes for Anodic Treatment of Alloys in Development of Resource-Saving Technologies

The effect of modifying additives on the processes of anodic treatment of alloys was studiedand the role of adsorption effects in development of resource-saving technologies for metal working wasestablished.

Development of an energy analysis for strip coal mining. Part III: Procedure for evaluating the energy intensity of technological processes

Traditional evaluation of the energy intensity of the technological processes of strip coal mining with respect to direct energy consumption is not exhaustive, since energy expenditures for the production of required resources in accompanying branches of industry, and the mining of fuel for the production of energy, the amount of which should be significantly higher than the sum directly expended for the mining and creation of the facilities for its execution are not considered. The proposed method for evaluation of the total energy intensity of technological processes is based on the link between basic energy outlays and production of the required resources. Evaluation not only of their direct energy intensity, but also with respect to individual forms of consumable resources is therefore critical to the analysis; this is the basis for a search for means of lowering the energy intensity of production on the whole and the development of resource-saving technologies.

Suggestions on resource-saving refractory technologies

Substantiated suggestions are made on the development of resource-saving technologies for a new generation of refractories and materials. Rapid organization of the production of the new generation of refractories will raise the refractory industry to a much higher level.
