Centrifugal Casting Rolling Mill Rolls

Centrifugal Casting Roll Rolling Mill Rolls A. Centrifugal Casting Definite Chilled Cast Iron Roll and Ring Properties The 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. Applications For Wire, bar and small section or light-duty material rod mills. B. Centrifugal and Static Casting Spheroidal Graphite (SG) Acicular Structure with Non Continuous Carbide Cast Iron Roll and Ring Properties Improve 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. Applications For Roughing rod/bar mills. C. Centrifugal Casting alloy Indefinite Chill Cast Iron Roll and Ring Properties The 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.

Applications 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. D. Centrifugal Casting Definite Chilled Cast Iron Roll and Ring Properties The 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. Applications For Wire, bar and small section or light-duty material rod mills. E. Centrifugal and Static Casting Steel Base Adamite Iron Roll and Ring Properties The 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.

Applications The Front finishing stands of section mill and hot strip mill, the roughing and intermediate stands of bar and wire mill. F. Centrifugal Casting High Speed Steel Roll and Ring Properties The shell is a high carbon alloy steel containing Cr, Mo, W, V and
