Surface Quality Ruler
- 1.The defects or holes should not more than two parts on the graphite electrode surface, and the defects or holes size not be allowed exceed the data in table below mentioned.
- 2.There is no transverse crack on the electrode surface.For longitudinal crack,its length should be not more than 5% of the graphite electrode circumference,its width should be within 0.3-1.0mm range.Longitudinal crack data below 0.3mm data should be negligible
- 3.The width of he rough spot(black) area on the graphite electrode surface should be not less than 1/10 of the graphite electrode circumference,and the length of rough spot(black) area over 1/3 of the graphite electrode length is not be allowed.
