Abstract
The utility model provides a pig machine molten iron casting prevents device that splashes, includes the molten iron chute, and chute stem bar department is provided with the splashproof groove, shelters from around the chute stem bar. The chute stem bar department is provided with the splashproof groove, shelters from around the chute stem bar, has blockked the all directions that the molten iron splashed, and the molten iron is blockked the back and is fallen into in the cast iron mould automatically, has effectively avoided the loss of splashing to reduce the waste and the human input of molten iron.
Description
Technical Field
The utility model relates to a device of splashing especially relates to a device of splashing is prevented in pig machine molten iron casting.
Background
The pig casting machine is used for casting molten iron smelted by the iron-making blast furnace and cooling the molten iron to form iron blocks with certain shapes. The splashing accumulation of the high-temperature molten iron causes the waste of the molten iron on one hand and damages other attached equipment attached by the splashing accumulation on the other hand, and the splashing iron slag needs to be cleaned frequently during the operation of a shift. Although each manufacturer makes many optimization measures in these aspects as much as possible, a great deal of splashing loss of the molten iron is still generated during the casting process.
Just there is a large amount of molten iron splash losses, sets up incomplete indisputable collection dolly under the molten iron chute tip, makes the molten iron that splashes fall into the dolly, takes away through the driving. On one hand, the blocking rate of molten iron is not improved, waste is caused, equipment investment is increased, and labor intensity for cleaning residues is high.
SUMMERY OF THE UTILITY MODEL
To the not enough of above-mentioned prior art, this application provides a device that splashes is prevented in pig machine molten iron casting.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a pig machine molten iron casting prevents device that splashes, includes the molten iron chute, and chute stem bar department is provided with the splashproof groove, shelters from around the chute stem bar.
The chute stem bar both sides are fixed with the trunnion, and the trunnion below is fixed with spacing angle steel, is provided with the hangers on the splashproof groove, and the hangers is hung on the trunnion, and spacing angle steel supports the splashproof groove downside.
The inner surface of the splash-proof groove is provided with a fireproof coating, and the outer surface of the splash-proof groove is fixed with a reinforcing rib.
The lower edge of the splash-proof groove is parallel to the moving direction of the cast iron mold, and the lower edge of the splash-proof groove is close to the upper edge of the cast iron mold.
The utility model has the advantages that: the chute stem bar department is provided with the splashproof groove, shelters from around the chute stem bar, has blockked the all directions that the molten iron splashed, and the molten iron is blockked the back and is fallen into in the cast iron mould automatically, has effectively avoided the loss of splashing to reduce the waste and the human input of molten iron.

Detailed Description
As shown in fig. 1-4, the molten iron casting anti-splashing device of the pig casting machine comprises a molten iron runner 1, wherein a flow nozzle of the runner 1 is provided with an anti-splashing groove 5 which shields the periphery of the flow nozzle of the runner.
The both sides of chute stem bar are fixed with trunnion 4, and the trunnion below is fixed with spacing angle steel 2, is provided with hangers 51 on the splashproof groove 5, and hangers 51 are hung on trunnion 4, and spacing angle steel 2 supports 5 downside in splashproof groove, and the position relation of 5 lower extremes in splashproof groove and chute stem bar is changed through the position that changes spacing angle steel, 5's of splashproof groove pushing off the slag angle promptly.
The splash proof groove 5 is formed by welding a plurality of steel plates, reinforcing ribs 52 are fixed on the outer sides of the steel plates, and refractory materials are arranged on the inner surfaces of the steel plates, so that molten iron cannot be attached to the splash proof groove when splashed.
Because the chain of the pig casting machine forms an included angle of 6-10 degrees with the horizontal plane and inclines upwards, the lower edge of the splash-proof groove 5 also forms an included angle of 6-10 degrees with the horizontal plane, namely the lower edge of the splash-proof groove 5 is parallel to the moving direction of the cast iron mold 3, and the lower edge of the splash-proof groove 5 is close to the upper edge of the cast iron mold 3.
In the operation process, molten iron flows to the direction of a runner spout in a molten iron runner 1, flows out of the runner spout after reaching the top end and falls into a cast iron mold 3, and the cast iron mold 3 moves forwards under the drive of a chain; the horizontal arrangement of the molten iron runner 1 and the objective requirement that a chain where the cast iron mold is located is inclined upwards by 6-10 degrees are met, when the molten iron flows down the cast iron mold from the runner nozzle, the fall of the molten iron inevitably exists and is uneven, in addition, the existence of residual moisture in a demolding film on the inner surface of the cast iron mold 3 causes partial iron slag to splash outwards, the existence of the splash-proof groove 5 blocks all directions of molten iron splashing, the molten iron automatically falls into the cast iron mold 3 after being blocked, and the splashing loss is effectively avoided. The device saves other devices for collecting the iron slag, reduces the labor input, saves the investment cost, and has simple manufacture and convenient installation.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
