二次切割

中碳钢连铸板坯存在着在冷却、运输、二次切割、存放过程中不时出现批量低温状态开裂的现象。

The medium carbon steel slAbs sometimes experience batch cracking in low temperature when cooled , transported , second cut or in later storage .

采用二次切割比一次切割可得到更为平整的切割断面，断面粗糙度Ra可达到1μm。

The cut sections of CVD diamond thick film will more level if laser secondary cutting technology is used and the roughness ( Ra ) of cut section can be 1 μ m.

模具在进行第二次线切割时表面产生的附加拉应力与材料已存在的内应力相叠加，其总应力超过了材料的抗拉强度，导致裂纹沿碳化物脆性开裂。

The resultant stress will exceed the tensile strength of the material , and caused the brittle cracking .
