Problems solved by technology

[0002] The water-cooled electric mold is a commonly used cooling device in smelting. At the same time, it is necessary to cool the molten iron and molten metal during the smelting process. However, for the molten iron or other molten metals produced by smelting, due to Under different cooling environments, different chemical reactions will still occur among the various chemical components inside, and the quality of the obtained smelted products is also different. However, most of the water-cooled molds in the prior art are smelted Water is directly put into the heat exchange between water and smelting water to achieve the purpose of cooling. However, due to the lack of reasonable design of the structure of the water-cooling mold, the temperature difference of each part of the smelting water after entering the water-cooling mold is Consistent, that is, after the smelting water enters the water-cooled mold from a high-temperature environment, it is based on the heat exchange with the water with a higher temperature first, and then with the water with a lower temperature. In the process, there is further reaction in the product in the water cooling process, which leads to the poor quality of the smelted product, and it is very easy to react with certain substances in the air (such as oxygen), which makes the prepared product The composition is more complex

Embodiment 1

[0029] Such as figure 1 As shown, a water-cooled electric mold consists of a mold body 5, a cooling tank 4 arranged in the mold body 5, a water inlet 6 arranged at the bottom of the mold body 5, a water inlet pipe 8 communicated with the water inlet 6, and the mold body The upper end surface of 5 is connected to the smelting water inlet 1 that enters the cooling tank 4, the molten iron outlet 3 that is connected to the upper end surface of the mold body 5 and extends out of the mold body 5, and the water cavity 7 formed by the mold body 5 and the cooling tank 4 and set The outlet pipe 2 on the side of the mold body 5 is formed, and the mold body 5 is composed of a mold body wall and a mold bottom to form a polygonal groove.

[0030] The cooling groove 4 is a groove recessed toward the bottom of the mold body 5 .

[0031] The cooling groove 4 is a downwardly recessed groove, and the bottom of the groove forms an arc.

[0032] In the arc, the bottom end of the arc is close to ...

Embodiment 2

[0039] Such as figure 1 Shown, on the basis of embodiment 1, a kind of preparation method of water-cooled electric mold comprises the following steps:

[0040] (1) Formwork preparation: select an open space downstream of the smelting furnace, level the open space, and pour concrete on the ground to form a plane. After the concrete solidifies, obtain the formwork bottom; then use bricks to form the formwork wall , the formwork wall is built into a double-layer with a sandwich layer, and concrete is filled in the sandwich layer, and vibrating rods are used to vibrate and squeeze tightly. After the concrete in the sandwich layer is solidified, a water inlet is opened on the bottom of the formwork, and The steel pipe is inserted into the water inlet, the upper surface of the steel pipe exceeds the surface of the mold bottom by 5-10cm, the lower surface of the steel pipe penetrates the bottom surface of the mold bottom by 5-10cm, and then the yellow mud is spread on the upper surfa...
