Problems solved by technology

At 950°C-970°C, the two poles in the electrolytic cell undergo a chemical reaction, that is, electrolysis. At this time, the slag scoop made of Q235 material will undergo rapid oxidation and partial melting.
At the same time, the melted iron is mixed into the molten aluminum, resulting in an increase in the iron content of the molten aluminum (iron content is a key indicator of aluminum grade), which directly reduces the quality of aluminum products
The smelting temperature of the molten iron in the intermediate frequency furnace is above 1450°C, and the slag ladle burns a lot. Smelting one furnace of molten iron consumes 2 pieces of slag shovel plates, resulting in a high cost of tools and equipment. Operators need to constantly replace the slag ladle. The production of the slag ladle and Maintenance costs are higher
In addition, the slag removal effect of the flat slag shovel plate is not good, and the slag removal efficiency is low

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] Such as figure 1 , figure 2 As shown, a high-temperature-resistant and anti-oxidation niobium alloy slag scoop for non-ferrous metal smelting slag removal, the slag scoop is a spoon-shaped structure, including a scoop body 1 and a scoop handle 2, and a leak hole 3 is opened at the bottom of the scoop body, The outer end of the scoop handle is processed with a mounting hole 4 that can be externally extended to extend the scoop handle, so that the slag scoop can be replaced and used, and the welding process is omitted. In this embodiment, the design length of the scoop handle is 200mm, so as to avoid contact with the molten metal surface during operation and be burned and melted. The outer end of the scoop handle is provided with three Φ11 mounting holes for bolt connection to lengthen the scoop handle. A plurality of leak holes 3 are provided at the bottom of ...

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...
