Abstract
The utility model discloses a roller casting die, which comprises a plurality of layers of sand boxes (1) which are laminated sequentially, wherein a roller cavity (2) for casting is formed in the sand boxes (1); a pouring gate (3) is formed on one side of the roller cavity (2) in the sand boxes (1); and the lower end of the pouring gate (3) is communicated with the bottom of the roller cavity (2) in the tangential direction. By the roller casting die, the impact of molten steel on the bottom of the roller cavity is relieved greatly; and the molten steel enters the roller cavity from bottom, waste residues or gas in the molten steel can be directly discharged overhead, and a cooled roller has the advantage of high strength.
Description
Technical field
The utility model relates to the roll casting die, especially the running channel of roller casting die.
Background technology
Roll is the vitals of roll forming.Roll need bear bigger roll-force in the operation of rolling, so the production of roll is all passed through to cast one-time formed.Roll production is cast through the roll casting die.The roll casting die comprises running channel and roll die cavity; Present known roll casting die is provided with cast gate on top, and cast gate directly is connected with roll die cavity top, and molten steel gets in the mould from cast gate; Fill with mould gradually; For preventing the back molten steel smaller volume contraction of casting, foundry goods can not be met the demands, in cast gate, inject a certain amount of molten steel and fill up.The shortcoming of above-mentioned roll casting die is because molten steel directly gets into from the top of roll die cavity, directly rushes at the bottom of roll die cavity, and the quality of molten steel is bigger; The impulsive force that produces is bigger; The bottom of fragile roll die cavity has reduced the quality of product, has also reduced the production qualification rate.Because molten steel gets into die cavity from top, and some waste residues will be stayed in the molten steel during cast, make that the roll strength that casts out is not very good simultaneously, influenced the quality of product.
The utility model content
The purpose of the utility model solves known roll casting die exactly and is prone to by the molten steel impact failure, and waste residue can not in time be discharged, and influences the quality of roll product and the problem of production qualification rate.
The technical scheme that the utility model adopts is: a kind of roll casting die; It comprises the sandbox that several layers laminates successively; Be useful on the roll die cavity of casting in the sandbox; It is characterized in that described sandbox is interior, a side of roll die cavity is provided with running channel, the running channel lower end is communicated with roll cavity bottom tangential.
Described and running channel roll cavity bottom junction is the ox horn shape.
The utility model beneficial effect is: because molten steel gets into the running channel end from running channel when casting; Because of ox horn shape running channel, reduced the flow velocity of molten steel, molten steel is cushioned; The tangential gets into roll die cavity, the impact that has alleviated molten steel breaker roll cavity bottom widely again; Molten steel gets into from the tangential, bottom of roll die cavity simultaneously, produces rotation, makes waste residue or gas in the molten steel more be prone to directly discharge from the top, and cooled roll has the high advantage of intensity.
Description of drawings
Fig. 1 is the utility model sketch map.
Fig. 2 is that the A-A of Fig. 1 is to sketch map.
The specific embodiment
Like Fig. 1, shown in Figure 2; A kind of roll casting die, it comprises the sandbox 1 that several layers laminates successively, present embodiment cheek 1 is a three-part flask; Be useful on the roll die cavity 2 of casting in the three-part flask; In the sandbox 1, a side of roll die cavity 2 is provided with running channel 3, running channel 3 runs through behind two layers of sandbox in three-part flask, running channel 3 lower ends are communicated with tangential, roll die cavity 2 bottom.The running channel of junction, roll die cavity 2 bottom is the ox horn shape.
Claims (2)
1. roll casting die; It comprises the sandbox (1) that several layers laminates successively; Be useful on the roll die cavity (2) of casting in the sandbox (1); It is characterized in that described sandbox (1) is interior, a side of roll die cavity (2) is provided with running channel (3), running channel (3) lower end is communicated with tangential, roll die cavity (2) bottom.
2. a kind of roll casting die according to claim 1 is characterized in that described running channel with junction, roll die cavity (2) bottom is the ox horn shape.
