Smelting furnace aluminum outlet casting nozzle and manufacturing method thereof

Abstract

The invention belongs to the technical field of aluminum product smelting processing, and discloses a smelting furnace aluminum outlet casting nozzle. The smelting furnace aluminum outlet casting nozzle comprises an outer covering pipe of a tubular structure, a mounting plate of a plate-shaped structure formed by extending the periphery of one end of the outer covering pipe, and a pouring pipe ofa tubular structure; and the pouring pipe is attached to the interior of the outer covering pipe and completely covers the inner wall of the outer covering pipe. The invention further discloses a manufacturing method of the smelting furnace aluminum outlet casting nozzle. The manufacturing method comprises the following steps of S1, manufacturing the outer covering pipe, S2, manufacturing an innermold pipe, S3, manufacturing a pouring cavity, S4, preparing a pouring solution, S5, pouring, and S6, solidifying. Compared with the prior art, the smelting furnace aluminum outlet casting nozzle isgood in using effect and long in service life, and meanwhile the safety performance is improved. The manufacturing method of the smelting furnace aluminum outlet casting nozzle provided by the invention is simple and convenient, and the size structure can be flexibly adjusted according to actual conditions.

Description

technical field [0001] The invention belongs to the technical field of smelting and processing of aluminum products, and in particular relates to an aluminum casting nozzle of a smelting furnace and a manufacturing method thereof. Background technique [0002] In the smelting and processing industry of aluminum products, the carrier of molten aluminum entering the chute from the melting furnace is called the aluminum casting nozzle of the melting furnace. The aluminum casting nozzle of the melting furnace is a very important part, because its structure, shape, size and material will affect the aluminum The quality and production efficiency of liquid smelting will be affected. In the related art, the aluminum nozzle of the smelting furnace is cast from common cast iron or cast steel. Because the aluminum nozzle of the smelting furnace is produced by integral casting, the related technologies have the following deficiencies: [0003] ① There are potential safety hazards: the...

Problems solved by technology

[0003] ① There are potential safety hazards: the pouring temperature of aluminum water is above 700°C, the heat transfer of cast iron is fast, and the temperature of the outer wall is high;

[0004] ② The service life is short. Long-term tracking and statistics of qualified aluminum casting nozzles found that: under the following working conditions, aluminum casting nozzles can only be used for 15 days

[0005] ③ Due to the excessive wall thickness, it is difficult to control the casting process, resulting in perforation and cracking at the weakest part of the four-wall performance, further reducing the service life;
