[0002] The top of the copper smelting furnace is an important part of the smelting furnace. Its refractory bricks are in a high temperature environment of up to 1600℃ for a long time. During this process, various alloy elements in the refractory material will react chemically with oxygen to form various oxides, resulting in the loss of alloy elements and accelerating the burning of refractory bricks. Therefore, controlling the top temperature is the key to reducing the oxidation of alloy elements.

The supports are provided with internal channels for circulation of cooling fluid and with side surfaces suitable for supporting multiple rows of refractory bricks or refractory bricks between adjacent furnace roof supports. The system achieves support and cooling of the furnace roof by providing independent internal channels in the supports, but the cooling efficiency and range are relatively small.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figures 1 to 4 A furnace roof structure of a smelting furnace includes a furnace body 1, which is made of refractory bricks. The top of the furnace body 1 is arc-shaped, and also includes a plurality of sleeves 2 arranged along the top periphery of the furnace body 1; a cooling water channel 3 is provided in the sleeve 2, and a plurality of sleeves 2 are arranged side by side on the top of the furnace body 1 to control the temperature of the refractory bricks on the top of the furnace body 1.

[0027] In this embodiment, a casing 2 is provided at the top of the furnace body 1, and a cooling water channel 3 is provided in the casing 2. By passing cooling water into the cooling water channel 3, heat is transferred between the casing 2 and the refractory bricks constituting the furnace body 1, thereby achieving a cooling effect. In addition, the casing 2 is arranged along the top periphery of the furnace body 1, so that the cooling water can cool the top of the entire furnace body 1, greatly improving the cooling efficiency and improving the uniformity of the top of the furnace body 1.

[0028] Specifically, the sleeve 2 is provided with a plurality of hooks 21; the hook 21 includes a hanging portion 211 of an inverted U-shaped structure, and hook portions 212 extending in a horizontal direction at both ends of the hanging portion 211; the hook portion 212 is embedded in the sleeve 2, and the hanging portion 211 is exposed outside the sleeve 2 and is used for being suspended outside.

[0029] Under the above design, the hook 21 firmly grasps the sleeve 2 through the hook portion 212. At the same time, the hook 21 is suspended outside through the hanging portion 211, which reduces the top load of the furnace body 1 and further avoids damage to the refractory bricks.

[0030] More specifically, a plurality of fasteners 11 are provided on the top of the furnace body 1 ; and the sleeve 2 is fixed to the top of the furnace body 1 by the plurality of fasteners 11 .

[0031] As a preference of this embodiment, the sleeve 2 is fixed to the top of the furnace body 1 by two groups of symmetrically arranged fasteners 11 , and both groups of fasteners 11 are composed of a plurality of fasteners 11 .

[0032] Under the above-mentioned preferred embodiment, the casing 2 can firmly grasp the refractory bricks constituting the furnace body 1 through the fasteners 11 to prevent the casing 2 from loosening, thereby making the heat transfer efficiency between the casing 2 and the refractory bricks higher.

[0033] As a further preferred embodiment of the present invention, the fastener 11 is a Y-shaped structure, the bifurcated portion of which is embedded in the furnace body 1 , and the straight portion is detachably connected to the sleeve body 2 .

[0034] In the above further preferred embodiment, the Y-shaped fastener 11 can not only firmly grasp the refractory bricks constituting the furnace body 1 , but also make the refractory bricks constituting the furnace body 1 fit more closely, thereby protecting the top structural strength of the furnace body 1 .

[0035] In this embodiment, in order to further improve the heat transfer efficiency between the casing 2 and the refractory bricks, there are two cooling water channels 3 arranged on both sides of the axis of the casing 2 .

[0036] Specifically, the cooling water channel 3 is provided with a water inlet 31 and a water outlet 32 ​​; the water inlet 31 and the water outlet 32 ​​are arranged on two sides of the casing 2 relatively and exposed.

[0037] In actual operation, cooling water enters from the water inlet 31 and returns to the external water pool from the water outlet 32 ​​as a cooling cycle, which reduces water resource consumption and has a high environmental protection coefficient.

[0038] In this embodiment, in order to further improve the efficiency of heat transfer, the cooling water channel 3 is a pipe made of copper.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
