摘　　要：为进一步控制GCrl5轴承铜碳化物液析，进行了加热温度与碳化物溶解扩散之间的关系研究，确定了GCrl5轴承钢比较合理的加热温度和保温时间，并将试验应用于现场。实际应用结果表明，在现有加热能力的务件下，将加热温度提高到1200～1280℃，保温时间在3h以上，使碳化物液析得到了控制，取得了明显效果。In order to control the carbide eliquation of bearing steel GCrl5 , the relationship of the heating temperature and solution - diffusion was studied. The appropriate temperature and holding time were determined for hearing steel GCrl5 and applied in pratice . The resuhs showed that under the condition of existing heating capability of furnace, the temperature was raised to1200 - 1280 ℃ and the holding time was kept over 3 hours, the carbide eliquation could be controlled, obvious effects have been achieved.
