Product Name: Alloy Chilled Cast Iron Roll (IC) Model NO.: IC roll Certification: ISO Type: Steel Rolling Equipment Condition: New Customized: Customized Casting Method: Static Cast Barrel Hardness: 60-85 Hsd Core Hardness: 35-45 Hsd Weight: ?20 Tons Size: as Per Drawing Trademark: CAMET Transport Package: Steel Rack Specification: ISO Origin: China Product Description Alloy chilled cast iron rollPropertiesThe mechanical properties are improved due to the presence of chilled surface strcture and the change of pinetree-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 working layer while the core is made of nodular cast iron, increasing as a result, both the wear-resistance and breaking strength.Chemical Analysis Designation of rollsCSiMnPSNiCrMoniCrMo chilled cast iron rolls (I)2.9/3.60.25/0.80.2/1.0≤0.4≤0.080.5/1.00.2/0.60.2/0.6NiCrMo chilled cast iron rolls (II)2.9/3.60.25/0.80.2/1.0≤0.4≤0.081.0/2.00.3/1.20.2/0.6NiCrMo chilled cast iron rolls (III)2.9/3.60.25/0.80.2/1.0≤0.4≤0.082.0/3.00.5/1.50.2/0.6NiCrMo chilled cast iron rolls(IV)2.9/3.60.25/0.80.2/1.0≤0.4≤0.083.0/4.50.5/1.70.2/0.6Physical PropertiesDesignation of rollsBarrel hardness (HSD)Neck hardness (HSD)Tensile strength (MPa)Depth of chilled lager200200/250250/300300NiCrMo chilled cast iron rolls (I)60~7032~50>15012~2515~3017~3520~45NiCrMo chilled cast iron rolls (II)62~7535~52>15012~2515~3017~3520~45NiCrMo chilled cast iron rolls (III)65~8040~55>15012~2515~3017~3520~45NiCrMo chilled cast iron rolls(IV)70~8532~45>15012~2515~3017~3520~45MicrostructureDesignation of rollsMicrostructureNiCrMo chilled cast iron rolls (I)Pearlite + cementite +ledeburiteNiCrMo chilled cast iron rolls (II)Fine pearlite + cementite +ledeburiteNiCrMo chilled cast iron rolls (III)Sorbite + cementite + ledeburiteNiCrMo chilled cast iron rolls(IV)Sorbite + cementite + ledeburiteApplicationDesignation of rollsApplicationNiCrMo chilled cast iron rolls (I)Section mill, bar mill, wire-rod mill narrow strip mill, finishing standNiCrMo chilled cast iron rolls (II)Section mill, bar mill, wire-rod mill narrow strip mill, finishing standNiCrMo chilled cast iron rolls (III)Section mill, bar mill, wire-rod mill narrow strip mill, finishing stand, tube stretch reducing millNiCrMo chilled cast iron rolls(IV)Section mill, bar mill, wire-rod mill narrow strip mill, finishing stand, tube stretch reducing mill
