Labeled as: the steel tube brick comprises a funnel brick 1, a cast tube brick 2, a center brick 3, a center brick outlet boss 31, a reinforcing steel belt 4, a leakage-proof steel clamp 5, a steel runner brick 6, a steel runner brick inlet groove 61, a bent chamfer 62, a steel runner brick outlet boss 63, a mold bottom brick 7, a mold bottom brick inlet groove 71, a steel runner brick 8, a steel runner brick inlet groove 81 and a steel runner brick outlet boss 82.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
The die casting pouring device shown in fig. 1 to 6 comprises a funnel brick 1, a cast pipe brick 2, a central brick 3, a runner brick 8, a runner tail brick 6 and a die bottom brick 7 which are sequentially communicated through an internal passage, wherein a central brick outlet boss 31 is arranged at an outlet of the central brick 3, a runner brick inlet groove 81 is arranged at an inlet of the runner brick 8, and the central brick outlet boss 31 and the runner brick inlet groove 81 are matched with each other.
In practical use, molten steel is injected from the funnel brick 1, flows to the central brick 3 along the cast pipe brick 2, and then flows to the runner brick 8 in the central brick 3, because the central brick outlet boss 31 is matched with the runner brick inlet groove 81, and the flow direction is from the central brick 3 to the runner brick 8, the molten steel flows from the boss to the groove direction, and the forward flow of the molten steel can reduce the pressure born by the refractory bricks at the joint, therefore, the leakage of the molten steel and the scouring of the molten steel to the refractory bricks can be prevented. Generally, the funnel brick 1 and the cast tube brick 2 are arranged along the vertical direction, the flow of the cast tube brick is realized by the self weight of molten steel, and when the molten steel flows to the central brick 3, the molten steel flows along the horizontal direction until the molten steel flows to the tail brick 6 and the bottom brick 7 of the mold. Molten steel enters the ingot mould from the mould bottom brick 7 and forms a steel ingot after cooling. Generally, it is preferred that the outlet of the central brick 3 is at least one, so as to fulfill the need of pouring the runner bricks 8 simultaneously in multiple directions. In order to remove the extension area of the tail end of the runner tail brick 6 after passing through the central hole and avoid a runner dead zone, a bending chamfer 62 is preferably arranged at the bending part of the internal passage of the runner tail brick 6.
Based on the same conception, the pressure at the joint position is reduced by realizing the downstream flow of the molten steel, the scouring of the molten steel to the refractory material of the steel brick is reduced, and the better centering in the installation process of the steel ingot mould is ensured, and the scheme is preferably selected: the outlet of the runner tail brick 6 is provided with a runner tail brick outlet boss 63, the inlet of the die bottom brick 7 is provided with a die bottom brick inlet groove 71, and the runner tail brick outlet boss 63 is matched with the die bottom brick inlet groove 71. And preferably, the outlet of the runner brick 8 is provided with a runner brick outlet boss 82, the inlet of the runner brick 6 is provided with a runner brick inlet groove 61, and the runner brick outlet boss 82 is matched with the mold bottom brick inlet groove 71.
In order to meet the corresponding requirement for conveying molten steel in the horizontal direction, the following scheme is preferred: the anti-leakage steel brick comprises at least two steel runner bricks 8 connected at the head, and anti-leakage steel clamps 5 are arranged at the joints of the adjacent steel runner bricks 8. The structure of the matched runner brick 8 is preferably reinforced by adopting U-shaped steel clamps at the periphery of the runner brick 8 and the connecting joint position thereof, so that the runner brick can be prevented from cracking and molten steel can be prevented from leaking. In addition, in order to ensure the structural strength of the runner brick 8 in actual use, it is preferable that the periphery of the runner brick 8 is provided with a reinforcing steel strip 4.
