Product Description

Alloy Steel Rolls

Alloy cast steel roll is made of top grade molten steel by arc furnace and advanced casting and technology of heating processing with high intensity, excellent thermal cracking resistance, toughness and abrasive resistance, applicable to rough and medium roll of profile steel, rough mill of hot rolled strip steel and supporting roll of hot rolled strip steel. Metallographic structure of roll is made of pearlite or tempered sorbite system.
