Basic Information

Centrifugal Casting Roll Rolling Mill Rolls PropertiesApplicationsCentrifugal Casting Definite Chilled Cast Iron Roll and RingThe mechanical properties are improved due to pressure of chilled surface structure and the change of pine tree-like structure. The hardness and type of matrix of roll depend on the conditions of application. The roll produced with centrifugal method basically eliminates the presence of graphite in its work layer while the core is made of nodular cast iron, increasing as a result, both the wear-resistant and breaking strength.For wire, bar and small section or light-duty material rod mills.Centrifugal and Static Casting Spheroidal Graphite (SG) Acicular Structure with Non Continuous Carbide Cast Iron Roll and RingImprove in wear-resistance and thermal fatigue resistance. High fracture toughness reduces the degree of fire cracking and helps to extend the campaign time. The high strength spheroidal graphite core overcomes the high loads.For roughing rod/bar mills.Centrifugal Casting alloy Indefinite Chill Cast Iron Roll and RingThe shell has a remarkable mechanical performance. With virtually no fall off in hardness due to the quantity of the quality if graphite remains basically unchanged throughout the working layer. The hardness of roll depends mainly on the type of matrix, namely sorbite, bainite or martensite.For the finishing stands of continuous rolling mill of strip and bar, the pre-finishing stands of high speed wire, the intermediate and the front of finishing stands if small section, also utilized in thin plate and straightening roll.Centrifugal Casting Definite Chilled Cast Iron Roll and RingThe mechanical properties are improved due to pressure of chilled surface structure and the change of pine tree-like structure. The hardness and type of matrix of roll depend on the conditions of application. The roll produced with centrifugal method basically eliminates the presence of graphite in its work layer while the core is made of nodular cast iron, increasing as a result, both the wear-resistant and breaking strength.For wire, bar and small section or light-duty material rod mills.Centrifugal and Static Casting Steel Base Adamite Iron Roll and RingThe microstructure consists of matrix and carbide with carbon content of 1.3-2.3%, depending on content of alloy and heat treatment process. The matrix consists of Pearlite or Bainite. With the addition of Cr, Mo and Ni for higher stability of carbide, enhanced high temperature resistance and strengthened matrix. The centrifugal roll has virtually no fall off in the hardness throughout the shell as well as highly wear and high temperature resistance and high load resistance etc.The front finishing stands of section mill and hot strip mill, the roughing and intermediate stands of bar and wire mill.Centrifugal Casting High Speed Steel Roll and RingThe shell is a high carbon alloy steel containing Cr, Mo, W, V and Nb. The microstructure consists of complex carbides embedded in a tempered martensitic matrix. Control of the carbon and a complex heat treatment allows the optimization of wear-resistance, thermal fatigue resistance and oxide film formation, whilst maintaining low residual stress values.Widely used as the F5 and F6 work roll for hot strip mills, the pre-finishing stands of high-speed wire mills and the finishing stands of bar mills.Centrifugal Casting Easy-cut High Speed Steel Roll and RingThe hardness is very uniformity in truly no fall off at the working depth with best wear resistance and machining performace. Its shell has W, Mo, V, Cr and Ti with high content as well as especially heat treatment get carbide +sorbite +bainite structure.Widely used at the intermediate stands of bar mill.Centrifugal Casting High Chrome Cast Iron RollThanks to its high content of M7C3 type carbide in the range of 20-30% and discontinuous network distribution of carbide, the roll offers a high wear-resistance performance. The matrix consist of tempered martensitic and sorbite with finely-dispersed secondary carbides (M7C3, M23C6 and M3C types), increasing therefore the wear-resistance of roll, the Cr2O3 enriched oxide film on the roll surfaces is highly resistant to oxidization and plastic strain, making the roll extremely suitable for steel hot rolling process.Mainly used for the front 3 and 4 finishing stands and the later roughing stands of continuous strip mill.
