Abstract

FIELD: metallurgy; processing of dispersed metal wastes, chips and thin wire. SUBSTANCE: temperature difference is attained over the capsule height below and above the metal melting point. When loading metal wastes, provision is made to ensure rise of density from capsule bottom upward, and graphite is additionally introduced into grainy material. Wastes are preliminarily compacted by pressing into briquettes of various density at different pressing forces. Difference of densities of wastes in height of capsule is attained by introduction into dispersed metal wastes of lumpy metal scrap, and also by layer arrangement in height of capsule of different fractions of metal wastes after their screening. Processing is carried out of wastes of one metal and of different metals. EFFECT: higher efficiency of metal wastes processing.

Изобретение относится к технике переработки дисперсных металлоотходов, стружки, тонкой проволоки. Известный способ переработки металлоотходов заключается в их спекании и переплаве в капсуле в оболочке зернистого сыпучего материала. Цель изобретения - повышение эффективности переработки металлоотходов. Новым в способе является то, что по высоте капсулы создают перепад температур ниже и выше температуры плавления металлов, причем при загрузке металлоотходов обеспечивают возрастание их плотности снизу вверх по высоте капсулы, а в зернистый материал дополнительно вводят графит. Кроме того, уплотнение отходов осуществляют их предварительным прессованием в брикеты различной плотности при различных усилиях прессования. Кроме того, перепад плотностей отходов по высоте капсулы достигают вводом в дисперсные металлоотходы кускового металлолома, а также послойным размещением по высоте капсулы различных фракций металлоотходов после их рассева. Кроме того, переработку отходов ведут из одного и того же металла и из отходов различных металлов. Изобретение может найти применение в металлургии.The invention relates to techniques for the processing of dispersed metal waste, shavings, thin wire. A known method of processing metal wastes is their sintering and remelting in a capsule in the shell of granular bulk material. The purpose of the invention is improving the efficiency of processing metal waste. New in the method is that the capsule height creates a temperature difference below and above the melting point of metals, and when loading metal waste, they increase their density from bottom to top along the height of the capsule, and graphite is additionally introduced into the granular material. In addition, the compaction of the waste is carried out by preliminary pressing it into briquettes of various densities with various pressing forces. In addition, the difference in density of waste along the height of the capsule is achieved by introducing lumpy scrap metal into the dispersed metal waste, as well as by layer-by-layer placement along the capsule height of various fractions of metal waste after their sieving. In addition, waste is recycled from the same metal and from wastes of different metals. The invention may find application in metallurgy.
