Description

Technical Field

[0001] The utility model relates to the use field of die casting steel pouring auxiliary materials, in particular to a device for hanging die casting protective slag. Background Art

[0002] Before casting steel, a certain amount of protective slag needs to be hung in the ingot mold at a certain hanging height. The hanging height of protective slag refers to the height of the bottom of the protective slag hung in the ingot mold from the bottom of the ingot mold. The hanging height of protective slag has an important influence on the quality of the die-cast steel ingot. After pouring, the molten steel rushes out from the rising eye at the bottom of the mold. After the molten steel contacts the protective slag hanging in the mold, the solid protective slag will quickly spread on the top of the molten steel and form a three-layer structure - the upper layer is the powder slag layer, the middle layer is the sintering layer, and the lower layer is the melting layer. The protective slag can cover the top steel liquid surface during the rising process of the molten steel in the mold. It can not only isolate the air to prevent the secondary oxidation of the molten steel, but also has a certain effect of absorbing inclusions in the molten steel. The hanging height of protective slag in the ingot mold is very important. If the hanging height is too high, the molten steel cannot contact the protective slag in time when pouring, and the molten steel cannot be protected by the protective slag in time, which is easy to be secondary oxidized.

[0003] Usually, the weight of each bag of protective slag is 2kg. The hanging weight of the protective slag for the commonly used 3T ingot mold is 6kg (1 bag of protective slag), and the hanging weight of the protective slag for the 5T ingot mold is 12kg (2 bags of protective slag). The operator puts the protective slag into the ingot mold through a hemp rope. The operator stands at the mold mouth and observes the distance between the protective slag bag and the mold bottom. When it is observed that the hanging height meets the process requirements of the corresponding ingot shape, the operator ties the rope in his hand to the middle of the steel pipe at the top of the riser, and uses the steel pipe at the riser to hang the protective slag in the ingot mold. After the steel pipe is placed on the top of the riser, the operator stands on the upper mouth of the riser to observe the hanging height of the protective slag. If the observed hanging height is higher than the process requirements, the rope is untied and readjusted.

[0004] The prior art has the following defects and deficiencies:

[0005] 1. The hanging height of the protective slag in the ingot mold is adjusted by the operator visually, and the hanging height is easily higher than the process standard requirements;

[0006] 2. The hanging height of 3T and 5T ingot protection slags needs to be adjusted by the operator by naked eyes, while the process requirements for the hanging height of 3T and 5T ingot protection slags are inconsistent. In the prior art, the hanging heights of 3T and 5T ingot protection slags cannot be clearly distinguished, which is not conducive to the standardized operation of the hanging height of the ingot protection slags;

[0007] 3. The operator stands at the mold mouth to adjust the hanging height of the protective slag, which is a high-altitude operation and has a greater safety risk.

[0008] 4. The steel pipe with protective slag hanging on the top of the riser has the risk of falling into the ingot mold during the casting process. Using steel pipes to hang protective slag has a greater quality risk. When the molten steel is cast into the riser, the operator needs to use a plug to insert heating agent, carbonized rice husk and other auxiliary materials into the riser. Once the plug touches the shorter steel pipe, the steel pipe is easy to fall into the ingot mold to form foreign metal inclusions in the ingot. Many foreign metal inclusions in the ingot cannot be found in the subsequent material flaw detection, which will seriously affect the quality of the steel. Utility Model Content

[0028] like Figures 1 to 3 As shown, according to an embodiment of the utility model, a device for hanging mold casting protection slag is provided, such as Figure 1 As shown, it includes a hemp rope 1 and a hanger 2, wherein, as Figure 2As shown, the hanger 2 includes four side bars 6 and a hanging bar 7, the four side bars 6 are connected in sequence to form a closed structure, and the hanging bar 7 is connected between two opposite side bars 6; the closed structure formed by the four side bars 6 connected in sequence can be placed on the riser 4 of the ingot mold 3; one end of the hemp rope 1 is connected to the bag opening of the protective slag 5, and the other end of the hemp rope 1 is connected to the hanging bar 7; the protective slag 5 can be hung into the ingot mold 3 through the hemp rope 1 by using the hanger 2. The length of the side bar 6 is greater than the length and width of the opening of the riser 4 of the ingot mold 3. The hanger 2 is connected in sequence by four side rods 6 to form a closed U-shaped structure. When hanging the protective slag 5 into the ingot mold 3, the four side rods 6 are placed on the four sides of the riser 4 respectively. When the molten steel is cast, the operator needs to use a plug to insert the heating agent, carbonized rice husk and other auxiliary materials into the riser 4. Once the plug hits the hanger 2, even if one corner of the hanger 2 falls into the riser 4 of the ingot mold 3, the entire hanger 2 will be stuck on the riser 4, and the hanger 2 will not fall into the ingot mold 3 to form foreign metal inclusions in the ingot. There is no risk of the hanger 2 falling into the ingot mold 3 during the casting process, ensuring that the ingot has no quality risk of foreign metal inclusions, thereby preventing the occurrence of scrapping caused by foreign objects falling into the ingot mold 3.

[0029] Furthermore, if Figure 3 As shown, the bracket also includes two vertical bars 8, a first cross bar 9 and a second cross bar 10. The first cross bar 9 and the second cross bar 10 are connected between the two vertical bars 8. The first cross bar 9 and the second cross bar 10 are both arranged horizontally. The position of the first cross bar 9 is higher than that of the second cross bar 10. The hanger 2 can be placed on the first cross bar 9 or the second cross bar 10. The distance between the first cross bar 9 and the ground is h4, and the distance between the top of the riser 4 of the 5T ingot-shaped steel ingot mold 3 and the pocket of the protective slag 5 is h3, and h3=h4. The distance between the second cross bar 10 and the ground is h5, and the distance between the top of the riser 4 of the 3T ingot-shaped steel ingot mold 3 and the pocket of the protective slag 5 is h3, and h3=h4. Before pouring steel, the bracket is used to adjust the hanging height of the protective slag 5 of the steel ingot molds 3 of different ingot shapes, so that the hanging height of the protective slag 5 in the steel ingot molds 3 of different ingot shapes can be quantified, so that the hanging height of the protective slag 5 meets the process requirements. The hanging height of the protective slag 5 is adjusted by the height of the first cross bar 9 and the second cross bar 10 on the bracket from the ground. Before the protective slag 5 is hung, the hanging height of the 5T ingot type protective slag 5 is adjusted by the first cross bar 9 of the bracket, and the hanging height of the 3T ingot type protective slag 5 is adjusted by the second cross bar 10 on the bracket. The heights of the first cross bar 9 and the second cross bar 10 on the bracket are fixed. The operator uses the bracket to hang the protective slag 5 in the 3T and 5T ingot type steel ingot molds, which can make the hanging heights of the protective slag 5 of different ingot types in the steel ingot mold 3 meet the standard, which is conducive to standardized operation.

[0030] Furthermore, two first hooks 12 are provided on the first crossbar 9, and the hanging rod 7 of the hanger 2 can be placed on the two first hooks 12. When the hanger 2 is placed on the first hooks 12 through the hanging rod 7, it is used to hang the protective slag 5 required for the 5T ingot shape. Two second hooks 13 are provided on the second crossbar 10, and the hanging rod 7 of the hanger 2 can be placed on the two second hooks 13. When the hanger 2 is placed on the second hooks 13 through the hanging rod 7, it is used to hang the protective slag 5 required for the 3T ingot shape. The bracket can be used to adjust the hanging height of the protective slag 5 of the ingot mold 3 of different ingot shapes. Figure 1 As shown, the process requires that the hanging height h1 of the protective slag 5 in the ingot mold 3 is 150mm-200mm, the bag length h2 of the protective slag 5 packaging bag is about 400mm, and the distance between the hanging rod 7 and the bottom of the ingot mold 3 minus the hanging height of the protective slag 5 and the length of the bag of the protective slag 5 can be obtained. The distance h3 between the bag opening of the protective slag 5 and the top of the riser 4 can be obtained. The length h3 is the actual length of the hemp rope 1 in the ingot mold 3 when the protective slag 5 is hung. Using a hemp rope 1 of this length to hang the protective slag 5 can ensure that the hanging height meets the corresponding process requirements. When hanging the protective slag 5, place the hanging rod 7 on the first hook 12 on the first crossbar 9 of the bracket, or place the hanging rod 7 on the second hook 13 on the second crossbar 10 of the bracket, place the protective slag 5 to be hung on the ground below the bracket, and then use one end of the hemp rope 1 to tighten the bag mouth of the protective slag 5 on the ground, straighten the hemp rope 1, and tie the other end of the hemp rope 1 to the hanging rod 7 of the bracket. At this time, the length of the hemp rope 1 is h3, and finally place the hanger 2 on the riser 4, and hang the protective slag 5 into the ingot mold 3. When hanging the protective slag 5 with this device, the operator does not need to stand at the mold mouth to adjust the hanging height of the protective slag 5, there is no risk of high-altitude operation, and the operation is safer.

[0031] Furthermore, the lower ends of the two vertical rods 8 are provided with supporting feet 11 to ensure the stability of the hanging rack 2.
