The influence of many space-oriented streams on melt was considered. It creates the regular, ordered mass-transfer, determining the homogeneity of thermal and chemical fields in melt, and providing the most favourable conditions of technological process of sulfide polymetallic raw materials treatment. Regularities of bath behavior are visually shown on physical models and are proved by the experimental check on real various-content melts in the scales from tens of kilos to several tones of sulfide copper-nickel materials. Tuyere construction was designed for the provision of the space-oriented air-blust supply. Reliability of these tuyeres was determined during the test firings of small samples at the blast crater temperature of 3000 ^oC. Total cooling consumption of water of the set of several tuyeres (taking into account their small sizes and minimal area of working head, placed in the heating chamber) is by 4–6 times lower, than the one of the one vertical tuyere with the suitable blowing production capacity. Several tuyeres with such construction give a possibility to the different application of tuyere, depending on the content of charge and given technological task. We offer the unit, mostly applied for realization of the continuous smelting of sulfide charge of matte converting. It may be either realized in two-phase form. In this case, the second area is used for slag reduction, flowing from the oxidation area by the reduction space-oriented streams with addition of required solid reducers, sulfidizers and fluxes.
