Indefinite Chilled Cast Iron Rolls

Indefinite Chilled Cast Iron RollsAlloy Indefinite Chilled Cast Iron Rolls is a cast iron with fine inter crystalline graphite evenly distributed throughout the working layer of roll barrel. The addition of alloy elements such as Manganese, Nickel, Chromium, and Molybdenum changes the matrix microstructure from pearlite, bainite to martensite. The present of small amount of fine graphite enhances the roll`s resistance to spallling, thermal crack and wearability. This roll has small hardness gradient in the working layer of roll barrel.Application: Intermidiate and finish stands of section mills, bar and rod mills, hot strip mill. Work rolls, skin pass rolls forMedium & heavy plate mills, hot strip mills.

Indefinite Chill Double Pour Rolls

Alloy Indefinite Chilled Cast Iron Rolls has a long working life span. Normally it`s applied to intermediate and finishing stands of long products and flat products hot rolling mills. Normally ICDP roll is added with chemical compositions like Cr, Ni, and Mo, which may increase the work layer depth. Thanks to the big qty of carbides existed in matrix structure of roll barrel, thus it has better wear resistance. Pros for ICDP rolls: high hardness, low hardness drop, good fire crack resistance, easy heat treatment process, that`s why it has been widely used all over the world. Application differs by hardness: For strip mills, the roll hardness normally 7585HS, For medium and heavy plate mill, hardness is relatively smaller as 7080HS

Enhanced Indefinite Chill Cast Iron Rolls

Enhanced Indefinite Chill Cast Iron Rolls The enhanced indefinite chilled cast iron roll is developed basing on the traditional ICDP. By adding the element of V, W, Ti, Nb, the wear resistance of the En-IDCP is improved. By the graphite formed inside the material, En-ICDP gets a better performance to prevent the thermal crack and the performance of anti thermal fatigue is improved.
