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 groove 4 arranged in the mold body 5, a water inlet 6 arranged at the bottom of the mold body 5, and a water inlet pipe 8 communicating with the water inlet 6, and the mold body 5 The smelting water inlet 1 connected with the upper end surface and entering the cooling tank 4, connected with the upper end surface of the mold body 5 and extending out of the smelting water outlet 3 outside the mold body 5, and the water cavity 7 and the water cavity formed by the mold body 5 and the cooling tank 4 The water outlet pipe 2 arranged on the side of the mold body 5 is composed of a polygonal groove formed by the mold body wall and the mold bottom.

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

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

[0032] In the arc shape, the bottom end of the ...

Embodiment 2

[0039] Such as figure 1 As shown, on the basis of Example 1, a method for preparing a water-cooled electric mold includes the following steps:

[0040] (1) Mold preparation: select an open area downstream of the smelting furnace, level the open area, and pour concrete on the ground to form a plane. After the concrete is solidified, the mold bottom is obtained; then bricks are used to form the mold wall , The mold body wall is built into a double layer with a sandwich layer, and the sandwich layer is filled with concrete, and the vibrating rod is used to vibrate and squeeze tightly. After the concrete of the sandwich layer is solidified, the water inlet is opened on the bottom of the mold, and The steel pipe is inserted into the water inlet, the upper end of the steel pipe is 5-10cm beyond the bottom surface of the mold, and the lower end of the steel pipe penetrates 5-10cm from the bottom of the mold. Then use yellow mud to spread on the upper surface of the mold bottom and press...

Abstract

The invention relates to the technical field of molds for smelting, in particular to a water-cooled electric mold and a preparation method thereof. The water pipe is connected with the upper end surface of the mold body and enters the smelting water inlet in the cooling tank, is connected with the upper end surface of the mold body and extends out of the molten iron outlet outside the mold body, and the water chamber formed by the mold body and the cooling tank and the water pipe arranged on the side of the mold body The mold body is composed of a mold body wall and a mold bottom to form a polygonal groove, so that the prepared water-cooled electric mold can effectively cool the molten iron for smelting, thereby improving the quality of the cooled molten iron and improving the quality of the molten iron. quality, reduces the oxidation of molten iron at high temperature, and also reduces the impurity content in molten iron.
