After industry application, the mix material carbon and granule segregation were overmatched the roller style and the sintering index were improved.
工业实施后混合料的碳与粒度偏析优于辊式布料，烧结指标改善。

Because of containing more sulfur and phosphorus in the steel, and more carbon, high hardness in material of surfacing welding, the pinch roller often turns up hot crack.
夹送辊堆焊时，由于母材的硫、磷含量较高及堆焊材料含碳量高、硬度大，常常产生热裂纹。

The effects of RE compound modificator on the mechanical properties and microstructure of high carbon high speed steel used for roller ring were investigated by SEM, EDS and EPMA.
