Non Continuous Carbide Rolls

NonContinuous Carbide Rolls  Rollsfor rough stand mills require a combination of some properties, some of whichcan be counteracted by the others. These properties include wearability, resistance of fire cracking and impact, hot hardness and hot strengh etc.Excessive network carbides will improve wearability and impact resistance butdramatically reduce fracture toughness. Under rough rolling process they canpromote fire cracking formation and added to form BainiticMartensitec(acicular)matrix, which is more wearable than conventional pearlitic matrix. TheMolybdenum can also improve the hot hardness of rolls. This type of roll ismanufactured from high alloy materials with special heat treatment. Carbidecontent in the matrix is less than 5%, which is satisfactory to the requirementof rough stand mill.
