高强与高韧冷轧辊堆焊焊条的研制

Development of the Surfacing Electrodc with the High Hardness and Toughness for Cold Roller

根据冷轧辊的实际工况条件确定其磨损机制 ,由材料强韧化复合原理研制了高强、高韧堆焊焊条。分析了某些合金元素及稀土氧化物对堆焊熔敷金属的影响。实验结果表明 。

The mechanism of wear was defined by practiced work condition of cold roller. The surfacing electrode with the high hardness and toughness was manufacturcd though compound theory of hardness and toughess of metal material. The influencc was analyzed for some alloy elements and rare carh oxidcs to hardfacing fusion metal. As a result, the electrode can satisfy request of practice condition.
