Casting device for roller casting manufacturing

Abstract

The invention discloses a casting device for roller casting manufacturing. The casting device comprises a casting cavity plate, wherein a cavity matched with the casting cavity plate is formed in thecasting cavity plate; a first fixing plate and a second fixing plate which are matched with the casting cavity plate are arranged at the top end and the bottom end of the casting cavity plate correspondingly; a casting groove is formed in the middle of the interior of the first fixing plate; a riser matched with the casting groove is arranged in the casting groove; a functional sleeve matched withthe casting cavity plate is arranged in the middle of the outer wall of the casting cavity plate in a sleeving mode; the gap between the inner wall of the functional sleeve and the outer wall of thecasting cavity plate is 10-15cm; a functional hole matched with the functional sleeve is formed in the middle of the interior of the functional sleeve; a functional interface matched with the functional hole is formed in the end, far away from the casting cavity plate, of the functional hole; and matching sleeves matched with the casting cavity plate are arranged at the top end and the bottom endof the functional sleeve correspondingly. The casting device has the beneficial effects that the stability of the whole casting process can be realized, the flexible operability of the whole casting process can be improved, and therefore the device is more flexible, safer and more practical.

Description

technical field [0001] The invention relates to the field of rolls, in particular to a casting device for roll castings. Background technique [0002] Rolls are an important part of roll forming. The rolls need to bear a large rolling force during the rolling process, so the production of the rolls is formed by casting. Roll production is casting through roll casting molds. The roll casting mold includes a runner and a roll cavity. The current known roll casting mold is provided with a gate on the upper part, and the gate is directly connected to the upper part of the roll cavity. The molten steel enters the mold from the gate and gradually fills the mold. Afterwards, the volume of molten steel becomes smaller and shrinks, so that the casting cannot meet the requirements, and a certain amount of molten steel is injected into the gate to fill it up. The disadvantage of the above-mentioned roll casting mold is that the molten steel directly enters from the upper part of the...

AI Technical Summary

Problems solved by technology

The disadvantage of the above-mentioned roll casting mold is that the molten steel directly enters from the upper part of the roll cavity and rushes directly to the bottom of the roll cavity. The quality of the product also reduces the production qualification rate. According to the Chinese Patent No. CN202291293, a roll casting mold announced, which greatly reduces the impact of molten steel on the bottom of the roll cavity, but at the same time, because the general pouring structure is single, the pouring method It is also very old-fashioned, which leads to the fact that the pouring equipment does not have a variety of flexible pouring methods. During the entire pouring process, it is difficult to do more operations on the solidification of molten steel, and it is difficult to follow up the pouring efficiency with a single pouring port.
