INTERACTION OF GAS PHASES WITH ACIDIC RUST MELT AND METAL

Summary: After ores are extracted from mines, they undergo various processing processes, after which they are smelted. The smelting process is carried out in various types of smelting furnaces and units. The working areas of these units are built of refractory materials. These refractory materials are eaten, destroyed, and fail for various reasons. One of the reasons that accelerates the erosion of refractory materials is the dross formed during the smelting process. This largely depends on the composition of the dross. The dross contains metal and non-metal oxides of various compositions and nature. Since the composition of the dross is of various nature, the mechanism of action is also different. The article clarifies the effect of dross on the working volume of the furnace during the smelting process, and proposals are put forward for its elimination. The acid open-hearth process allows steel to be produced with a lower gas content compared to the basic process.
