liquid separation

With billet of 150 mm×150 mm and two heating processes to produce steels of larger or smaller than Φ 38 mm,the liquid separation of bearing steel got controlled.

石钢二轧厂为进一步控制GC r15轴承钢碳化物液析,采用150mm×150mm坯型、两种加热工艺制度生产<Φ38mm、≥Φ38mm规格钢材,使轴承钢的液析得到了控制,取得了明显效果。

Carbide eliquation is one of the most damaging asymmetrical Carbide in Bearing Steel GCr15,It can reduce fatigue life of the Bearing, this article has analyzed the effect of heating on carbide eliquation.

碳化物液析是高碳铬轴承钢碳化物不均匀性中最有害的一种,可明显降低轴承零件疲劳寿命,本文就加热温度对轴承钢液析的影响进行了分析。

With the original process,the qualification rate of the liquation carbonide was only 75.

原工艺下液析碳化物合格率仅为75。

Through controlling and reducing the carbide eliquation a batch of quality GCr15 bearing steel bars were successfully produced in 2006.

石家庄钢铁有限责任公司为进一步提高轴承钢质量,满足高端用户的需求,2006年批量生产GCr15轴承钢棒材,为控制并降低碳化物液析级别,进行了理论探讨和生产实践,取得了明显效果。

In order to eliminate the carbide eliquation and improve the banded structure, the relationship of the heating temperature and solution-diffusion was researched, the appropriate temperature and holding time were determined for GCr15 bearing steel and the test results were put in practice.

为消除轴承钢中碳化物液析,改善带状组织,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GCr15轴承钢比较合理的加热温度和保温时间,并将试验结果实施于现场。
