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。

If there is more sulfur in the steel and the steel contains many inclusions with flake configuration in the same plane with high density, lamellar tearing tends to happen with high probability.
钢材中含硫量越多，夹杂物以片状形态大量密集于同一平面，发生层状撕裂的倾向就越大。

Insoluble sulfur is a high performance vulcanizing agent of the rubber and vulcanizing accelerator, which is mainly used to produce steel radial-ply tire.
