摘要
研制了柴油机活塞成型冷却油道的新型水溶芯。这种水溶芯强度高，表面光洁，水溶性好，性能稳定，成本低。用这种水溶芯铸出的冷却油道位置准确，轮廓清晰，其表面粗糙度可达到Ｒａ３．２～６．３μｍ。
Investigation was made on the water dissolved core of piston of internal combustion engine cooling oil groove. The water dissolved core has many advantages such as high strength, smooth surface, good water dissolvability, stable performance and low cost. The cast cooling oil groove is precisely positioned and has clear outline, its roughness of surface can reach Ra 3.2～6.3μm.
