Abstract

The invention discloses a high-temperature-resistant antioxidant niobium alloy slag ladle used for nonferrous metal smelting and slagging. The slag ladle is of a spoon-shaped structure, and comprisesa ladle body (1) and a ladle handle (2), wherein leakage holes (3) are formed in the bottom of the ladle body; the ladle body and the ladle handle are manufactured from a high-temperature-resistant antioxidant niobium alloy which is Nb-1Zr; and an MoSi2 high-temperature-resistant antioxidant coating material is sprayed to the surface of the ladle body and the surface of the ladle handle. The high-temperature-resistant antioxidant niobium alloy slag ladle disclosed by the invention is not liable to melt, is long in service life, can be used in a circulating mode by many times, reduces tool consumption and manufacturing and maintaining cost, can prevent molten iron from mixing into molten aluminum to reduce aluminum product quality, and is high in slag removal efficiency.

Description

technical field

[0001] The invention belongs to the technical field of special tools for smelting non-ferrous metals, and in particular relates to a high-temperature and anti-oxidation slag ladle used for smelting slag breaking in electrolytic cells and intermediate frequency furnaces. Background technique

[0002] The slag scoop is an important slag removal tool in the slag breaking operation in the non-ferrous metal smelting process. It is currently widely used in the production of electrolytic cells and intermediate frequency furnaces in the aluminum industry. The slag scoop used in the prior art is a flat slag scraper made of Q235 material, which has moderate carbon content, relatively good comprehensive performance, good coordination of strength, plasticity and welding performance, and its melting point is above 1495°C. At 950°C-970°C, the two poles in the electrolytic cell undergo a chemical reaction, that is, electrolysis. At this time, the Q235 material slag scoop wi...
