Product Description

      Rolls for roughers require a combination of some properties, some of which can be counteracted by the others. These properties include wearability, resistance of fire cracking and impact, hot hardness and hot strength etc. Excessive network carbides will improve wearability and impact resistance but dramatically reduce fracture toughness. Under rough rolling process they can promote fire cracking formation and added to form Bainitic/Martensite (acicular) matrix, which is more wearable than conventional pearlitic matrix. The Molybdenum can also improve the hot hardness of rolls. The type of roll is manufactured from high alloy materials with special heat treatment. Carbide content in the matrix is less than 5%, which is satisfactory to the requirement of roughers.
