The two ends of the runner are respectively connected with the front box and a casting nozzle; and flow distribution blocks are arranged in the runner, so that after a melt enters the runner, the flow rate of the melt is accelerated, the speed of heat exchange is increased, and the flow distribution manner of the aluminum melt at the rear end is optimized so as to ensure that the temperature of the aluminum melt flowing into the casting nozzle can be uniformly distributed.
Description
Technical field
The utility model relates to aluminium rolling casting technology field, case cross gate before particularly a kind of casting.
Background technology
In the aluminium casting and rolling production process, case before aluminum melt arrives through chute flows into lip through cross gate again, realizes the aluminium casting-rolling technology.During aluminum melt process chute; Side at aluminum melt is provided with flow straightener; The fluctuation of minimizing aluminum melt, the feasible temperature that the aluminum melt of flow straightener one side is set is higher than the temperature of opposite side aluminum melt in the chute, makes the temperature that flows into preceding case aluminum melt have certain inhomogeneities; Aluminum melt flow through preceding case, cross gate, lip; Path, flow velocity are rules, stable; Lip both sides flow process is big and the middle part flow process is little, makes the heat transmission speed between aluminum melt slow, therefore; There is the even situation of temperature distributing disproportionation equally in the aluminum melt that flows into Casting or rolling nozzle, thereby influences the quality of casting product.
The utility model content
The purpose of the utility model is to overcome above difficulty, and a kind of preceding case cross gate of aluminum melt Temperature Distribution casting more uniformly that flows into lip that makes is provided.
The technical scheme of the utility model is:
Case cross gate before a kind of casting, the two ends of said cross gate are connected with lip with preceding case respectively, are provided with first branching block in the said cross gate.
Further, the quantity of said first branching block is the 2-3 piece.
Further, the part between said first branching block and the said lip is provided with second branching block.
Further, the quantity of said second branching block is the 2-5 piece.
Further, in said second branching block spacing between adjacent two branching blocks less than the branching block of both sides in said second branching block distance to pairing cross gate inwall.
Further, the corner angle of said first branching block and said second branching block are arcuate structure.
Further, the height of said first branching block and said second branching block is identical with the height of said cross gate.
Case cross gate before the casting that the utility model provides; In cross gate, be provided with branching block, make the flow velocity quickening after aluminum melt gets into cross gate, speed the speed of exchange heat; Optimize the cloth stream mode of aluminum melt, thereby the temperature of the aluminum melt that flows into lip can be evenly distributed in the rear end.
First branching block is set in cross gate, makes the reduced cross-sectional area of aluminum melt, according to mass conservation law through preceding case arrival cross gate; The speed of aluminum melt after getting into cross gate increases; Atomic motion is violent, and exchange heat is obvious, can significantly improve the big problem of the aluminum melt temperature difference.
Second branching block is set between first branching block and lip, optimizes the cloth stream mode of aluminum melt, further improve the uniformity of aluminum melt temperature in the rear end.Spacing in second branching block between every adjacent two branching blocks is less than the branching block of both sides in second branching block distance to pairing cross gate inwall, and when making aluminum melt flow through second branching block zone, the flow of both sides is greater than the middle part; Thereby it is poor with middle flow process to the lip both sides to reduce aluminum melt; Aluminum melt is when just flowing into lip, and the aluminum melt of both sides mixes with middle aluminum melt, and interatomic collision disperses the high slightly aluminum melt of lip mid portion temperature; Thereby lip mid portion temperature reduces; The both sides temperature raises, and realizes the uniformity of aluminum melt Temperature Distribution in the lip inner chamber, has improved the quality of casting product.
Case cross gate before the casting that the utility model provides, the corner angle of the branching block of set inside are arc, reduce the resistance of aluminum melt in flow path, increase mobile.
