Embodiment Construction
[0020] Such as Figure 4 — Figure 8 As shown, it is the pouring cooling system of the high carbon steel thin-walled annular casting of the present invention. In this system, an annular cooling channel 8 is arranged at intervals near the thinnest wall thickness inside the thin-walled cavity of the casting. The annular cooling channel 8 is provided with Extending to the air inlet pipe 9 and the air outlet pipe 10 outside the sand box, the air inlet pipe 9 is connected with the compressed air source; on the outside of the thin-walled cavity of the casting, a number of tie bars 12 connected with the casting cavity are pasted, and the length direction of the tie bars 12 It is arranged along the axial direction of the annular thin wall.
[0021] In order to further promote the uniform cooling and solidification of the thin-walled parts, the above-mentioned annular cooling channel 8 includes several layers of arc-shaped cooling pipes arranged at intervals along the axial direction ...
