The stages of introduction of computer simulation tools in the production process of The Rostov Foundry are considered. A system for estimating the results of simulation is proposed, which includes the definition of complex parameters that allow an assessment of the causes and the probability of formation of shrinkage defects. An equation that determines a relationship between results of simulation and actual rejects in production is proposed. The feeder operation index is suggested to use for estimation of the reasons for the formation of shrinkage defects.

In progress to assess the impact of chemical treatment of recycled water in the production of mineral wool, its salinity and the degree of clarification found that the most suitable reagent to achieve the objectives is a 25% aqueous ammonia solution. It is shown that the optimum quantity of ammonia to initiate the process of deposition is in the range of 4–6 ml/dm3, lower number gives a noticeable lightening of recycled water and reduction of solids, a larger leads to a re-dissolution of already formed sludge and therefore to reduce the share of bleached water and increase the content of dissolved salts.

The most advanced and universal way of chips recycling of ferrous metals is the technology of direct chips remelting in rotational tilting furnaces (RBF) directly at the enterprises-sources of waste generation. However common practice of iron and steel chips recycling is based on its briquetting and subsequent remelting in traditional furnaces.

For cost reduction when chip briquetting and organization of hot briquetting sections in places of its formation highly efficient equipment – rotational dryer and RBF is proposed. The possibility and effectiveness of developed furnaces for lowand high-temperature chip heating in briquetting lines is proved. Thermal efficiency of such furnaces when dispersed materials heating is much higher than drum or feed-through furnaces. Hot briquetting of shavings reduces the pressing force, which reduces the specific energy consumption. The use of rotary kilns can reduce technological operations and equipment of production sites for the manufacture of briquettes
