Detailed Product Description: | Graphite cold iron Casting, cold iron to improve the role and prevent casting riser produce shrinkage, shrinkage, casting quality assurance plays a more important role in the lost foam casting and the general casting method can be used as cold iron. Outside the cold iron when placed in the Chung sand;-cooled iron mold in the system model embedded or bonded to the inside, outside cold iron can also be extended to the model, but fixed in the sand. Placed inside and outside the principle of cold iron and cold iron type, size and general casting similar. Difficult one in the riser feeding site to prevent Shrinkage. Two parts and to prevent rapid changes in wall thickness cross-site cracks. Three used in conjunction with the riser, to strengthen the casting solidification conditions, the expansion riser feeding distance or range to reduce the number or volume of the riser. Four individual heat cold iron to accelerate the cooling section, while the entire cast is close to freezing, can prevent or reduce the casting distortion, but also improve the process production rate. Five to improve the casting of local microstructure and mechanical properties. Such as the refinement matrix structure, improve the casting surface hardness and wear resistance. Six thick-walled castings to reduce and prevent segregation. The role is to accelerate the cold iron cast iron in the casting process of a part of the cooling rate. Cast iron needs because of its structure caused by uneven thickness of the various parts, some parts very thick, the cooling process for the slow cooling of the wall thickness of the thin parts of the cooling fast, making all parts of the same casting uneven cooling rate . Result may produce shrinkage, or the thin-walled parts of the rupture. To avoid this phenomenon, modeling is completed, the wall thickness in parts of Canada to put the cold iron, use it to absorb the hot metal temperature, speed up this part of the cooling rate, shortening and other parts of the cooling wall thickness of the time difference. |
