Abstract
At the large-scale test facility, manufactured at West-Siberian iron and steel plant from 1992 till 2001 40 series of experiments were accomplished, which enabled to confirm trueness of theoretical and designing solutions of jet-emulsion metallurgical process (JER) and to perfect the design of the facility. Several new low-energy intensive technologies were tested experimentally, including a technology of direct reducing of powdered ores and wastes (sludges, oiled scale) without agglomeration, a technology of obtaining manganese alloys from poor powdered ores, a technology division of titanium-magnetite concentrates into iron and conditional titaniferous slag, and a technology of metal direct reduction with simultaneous production of synthesis-gas. It was shown, that application of JER process is particularly effective for processing of poor powdered ores, as well as powdered iron-containing and coal wastes, by direct reduction in one stage without agglomeration. Possible variants of diversification of technological schemes of production considered for integrated steel plants and machine-building plants, creation of mini-mills of complete cycle (ore‒steel). An example of a layout solution for a technology based on JER process in existing building presented. The level of the development enables to design and together with a machine-building plant to construct on “turn-key” base a pilot facility of industrial scale. The advantages of the process mentioned above enable to get a quick pay-back, particularly for situation of processing of powdered wastes and ores.

Summary
В первой части этой статьи [1] были рассмотрены предпосылки, приведшие к созданию нового струйно-эмульсионного металлургического процесса (СЭР). Possible variants of industrial implementation of jet-emulsion metallurgical process and new technological schemes on its base. Агрегат типа СЭР может использоваться в качестве газификатора пылевидных фракций угля, но наиболее экономичным является вариант с использованием смеси угля и пылевидных железосодержащих отходов. Процесс типа СЭР и другие процессы прямого восстановления позволяют поставить задачу изменения традиционной структуры металлургических комбинатов, так как при этом устраняются агломерационное, коксохимическое, а также доменное производства.
