Embodiment Construction

[0027] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0028] Different from the melting furnace in the prior art, the melting furnace according to the embodiment of the present invention has been improved in terms of the structure and material of the furnace body, prolonging the service life of the melting furnace under extremely cold and extremely hot working conditions, and prolonging the overhaul interval.

[0029] For example, Panzhihua Iron and Steel Vanadium used to produce V 2 o 5 Vanadium melting furnace, the furnace is at a high temperature of about 600 ℃ for a long time, and the red vanadium powder is melted into a liquid state. The melt has acid corrosion. Under the long-term high temperature, corrosion, and washing of the melt, the furnace wall and furnace bottom lining brick Fracture and deformation are fast, especially causing many gaps in the masonry between the furnace bottom and the furnace and...

Abstract

The invention provides a vanadium product melting furnace, which comprises a furnace shell, a furnace lining structure, a feed port, an air inlet and a flue, wherein the furnace shell forms an external structure of a furnace body of the melting furnace; the furnace lining structure is formed on the inner side of the furnace shell of the melting furnace and forms a hearth of the melting furnace; the feed port is formed in the upper surface of the furnace shell; a vanadium product to be melted is placed into the furnace through the feed port; the air inlet is formed in a lateral surface of the furnace shell for introducing an amount of air required in a melting process into the melting furnace; the flue is arranged on the lateral surface of the furnace shell for discharging flue gas produced in a vanadium product melting process; and the furnace lining structure comprises a furnace side wall and a furnace bottom and is provided with a set-back structure which is built with the furnace side wall gradually setting back towards the interior of the furnace and is crossed with the furnace bottom.

Description

technical field [0001] The invention relates to a melting furnace for vanadium products, more specifically, to a furnace lining structure for a melting furnace for vanadium products. Background technique [0002] Application of melting furnaces to smelt vanadium products to produce V 2 o 5 Vanadium flakes are a common method and have been widely used. The existing melting furnace for vanadium products is used for melting red vanadium powder into liquid at high temperature. [0003] figure 1 is a structural diagram of a melting furnace according to the prior art, figure 2 is along figure 1 A cross-sectional view taken along line A-A in image 3 is along figure 1 A cross-sectional view taken along line B-B in . [0004] Such as Figure 1 to Figure 3 As shown, the vanadium product melting furnace 10 according to the prior art includes: a furnace shell 11, which forms the outer structure of the melting furnace 10; The smelting of products; feed port 13 is arranged on ...
