Description
Technical Field
[0001] The utility model belongs to the technical field of iron and steel metallurgy, and particularly relates to a device for melting chip-shaped alloy. Background Art
[0002] In the process of molten steel smelting, a certain amount of alloy materials need to be added to the molten steel for alloying. Due to experimental requirements, some special alloys need to be cut into chips first and then added to the molten steel for alloying.
[0003] Since the density of the chip-shaped alloy is much smaller than that of the molten steel, it basically floats on the surface of the molten steel. The stirring force of the existing intermediate frequency furnace is insufficient to stir the chip-shaped alloy to the middle part of the molten steel, resulting in a low alloy recovery rate. At the same time, a part of the chip-shaped alloy is easily adsorbed by the molten slag on the surface of the molten steel. Since the amount of alloy added to the experimental steel is small and in the form of chips with a light weight, it floats on the surface of the molten steel and cannot enter the lower middle part of the molten steel, resulting in poor melting and absorption of the alloy. Eventually, it enters the steel slag and the recovery rate is low.
[0004] In view of the above factors, a device for melting chip-shaped alloy is specially designed to add the chip-shaped alloy to the lower middle part of the molten steel, reduce the oxidation of the alloy, prevent the alloy from being adsorbed by the molten slag, enable it to be fully melted and absorbed in the molten steel, and be evenly distributed in the molten steel, thereby improving the recovery rate of the alloy.
