Abstract

Method of low-tonnage recycling of dispersed iron-containing metal wastes without their preliminary preparation by solid-liquid phase reduction in a rotation tilting furnace to produce cast iron or steel relates to foundry industry and metallurgy and is developed for directly use in plant - sources of such wastes (machine building, metallurgy, metalworking productions, etc.) and permits to convert production and consumption of metal into closed, ecologically clean cycle, providing production profitability even at small volumes (less than 1000 t/year) and considerable nonehomogeneity of wastes to be processed. The whole process of recycling is sequentially realised in one unit - the rotation tilting furnace (Fig. 1 and 2), comprising a housing 1 and a swivel cover 3 protected by a multilayer lining 12, a support post 10, a movable 7 and support 8 frames, drives 2 of the housing rotation, the tilting cover turn and the tilting furnace inclination 9. A burner 6, a branch pipe for removing waste gases 5, a branch pipe for oxygen input 11, an inspection hole 4, sensors of temperature control and atmosphere content in the furnace are arranged on the swivel cover 3.
