Alloy Cast Steel Rolls |
|
Carbon content in these rolls is in the range of 0.50% to 1.20%. Heat treatment gives either a spheroidised or fine pearlite matrix for high toughness. Small areas of carbide increase the wear resistance. The heat treatment of these rolls involves normal double annealing followed by tempering cycle which improves toughness and thermal shock resistance. The microstructure is primarily pearlitic with broken cementite. These types of Rolls offer mechanical strength of higher degree with good weldability. |
