| 防止热裂的措施:在实际浇注系统中应避免局部过热，减少内应力。模具和核心边坡必须确保上述5°,倒了立管在凝固可以抽芯成型,砂芯在必要时可以代替金属核心。 Measures to prevent hot cracking: local overheating should be avoided and internal stress should be reduced in the actual gating system. The mold and core slope must ensure the above 5 °, the inverted riser can be formed by core pulling during solidification, and the sand core can replace the metal core when necessary. 控制镀层厚度，保证铸件冷却速度一致。根据铸件厚度选择合适的模具温度。细化合金组织，提高热裂能力。改善铸件结构，消除尖角和壁厚突变，减少热裂纹倾向。 Control the coating thickness to ensure the consistent cooling rate of castings. Select the appropriate mold temperature according to the thickness of the casting. Refine the alloy structure and improve the hot cracking ability. Improve the casting structure, eliminate sharp corners and sudden changes in wall thickness, and reduce the tendency of hot cracks. |
