It may be caused by an inherent quality problem of the electrode itself or by improper furnace operation, and both have clear fracture mechanisms.<\/p>\n<p style=\"text-align: justify;\">How to make a preliminary judgment based on fracture characteristics<\/p>\n<p style=\"text-align: justify;\">If the fracture is in the electrode body (not at the joint)<\/p>\n<p style=\"text-align: justify;\">This situation tends more toward electrode quality or thermal stress issues:<\/p>\n<ul style=\"text-align: justify;\">\n<li>Quality defects: Internal transverse cracks, threaded socket defects, or insufficient bulk density and strength in the electrode body.<\/li>\n<li>Thermal shock damage: Poor thermal shock resistance of the electrode, with deep cracks forming at the end under the high temperature of the arc, leading to transverse fracture.<\/li>\n<li>Thermal stress: Under high-power operation, local heating of the electrode generates enormous thermal stress that exceeds the material strength and causes cracking.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">If the fracture is at the joint or near the holder<\/p>\n<p style=\"text-align: justify;\">This situation tends more toward operational or equipment problems:<\/p>\n<ul style=\"text-align: justify;\">\n<li>Broken by collapse: Scrap forms a &ldquo;bridge&rdquo; and then suddenly collapses, directly breaking the electrode or causing a huge lateral impact; the fracture is often near the clamping point.<\/li>\n<li>Improper clamping: The holder is not clamped on the designated white line area, foreign matter on the clamping surface causes stress concentration, or non-vertical electrode connection generates additional bending moment.<\/li>\n<li>Joint problems: Although joint breakage often originates from quality issues (such as poor machining accuracy or high electrical resistivity), non-standard joining operations (such as incomplete cleaning or improper torque) can also directly lead to loosening or breakage. Some data show that in EAF steelmaking, more than 80% of electrode usage accidents are related to joint breakage or loosening.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">Recommended troubleshooting steps<\/p>\n<ol style=\"text-align: justify;\">\n<li>Examine the fracture surface: Check whether it is a clean brittle fracture (leaning toward quality\/thermal stress) or a fracture with signs of wear and loosening (leaning toward operation\/clamping).<\/li>\n<li>Check the records: Review the operations before the fracture to see whether there were abnormalities such as scrap collapse, oxygen blowing disturbance, prolonged overload, or short circuit.<\/li>\n<li>Compare with standards: Verify whether indicators such as bulk density, flexural strength, and electrical resistivity of the electrode and joint meet the requirements for the current furnace type (such as ultra-high power).<\/li>\n<\/ol>\n<p style=\"text-align: justify;\"><strong>About Us<\/strong><\/p>\n<p style=\"text-align: justify;\">Handan Qifeng Carbon Co., Ltd. is a large carbon manufacturer in China, with more than 15 years production experiences, can provide carbon materials and products in many areas.
