The Knowledge You Should Learn About the Alloy Chilled Cast Iron Roll

Alloy Chilled Cast Iron Roll is one of most popular iron rolls with highly Competitive market. Now, we introduce the basic knowledge about the alloy chilled cast iron roll

Alloy Chilled Cast Iron Roll

Alloy Chilled Cast Iron Rolls are mainly used in intermediate roll stand and finishing stand of the sheet, wire rod, section steel, pipe. Their body hardness HSD55-85, roll neck tensile strength 150-220Mpa.The iron rolls are made according to standard ISO, GB, ASTM, DIN, JIS. There is no free graphite in the working layer of alloy chill cast iron roll, it is featured as high hardness, good wear-resistance, the micro metallographic microstructure is fine pearlite and carbides.

Application

The finishing mill for section steel, wire rod, strip, thin plate, and bar;

The pre-finishing stands of high-speed wire;

The roll ring of stretch reducing mill for seamless steel tube.

High-Cr Composite Spin-Cast Iron Roll

The high-chromium composite cast iron roll is made of wear-resistant high-chromium white cast iron as the outer layer material of the roll body. The ductile iron is generally used as the material of roll core and the roll neck. The high alloy composite cast iron roll produced by the centrifugal

Due to the presence of lath-shaped M7c3, eutectic carbide, chrysanthemum M2c eutectic carbide and granular M23C6 secondary carbide in the matrix, the high chromium composite cast iron roll has excellent wear resistance and high Resilience and impact resistance, thus it is widely used as the rough rolling and finishing rolling work rolls in the hot strip rolling mill, the wide and medium plate rolling mill. as well as the finishing rolling work rolls in the small section steel and sheet rolling mill.

Alloy Indefinite Chilled Cast Iron Roll

The Alloy Indefinite Chilled Cast Iron Roll is a kind of centrifugal composite spin-cast iron roll, it has a double chemical, the outside has high tensile strength and the inside is a lower one, the hardness drop is lower. It is usually used as work roll for the finishing mill to roll the angles, bars, flats and so on.

The indefinite chilled cast iron roll is a roll between chilled cast iron and grey cast iron with a carbon content of 2.5-3.5% and a silicon content of 0.7-1.6%. The structure of the roller body changes uniformly in the outward direction, and the chilled structure gradually transitions to the gray mouth structure, and the chill layer does not change significantly.

Application

work roll of bar & wire rod mill, hot strip mill, cold strip mill, PC mill, section mill, plate rolling mill, non-ferrous mill, etc.

High NiCr Indefinite Chilled Composite Spin-Cast Roll

High NiCr indefinite chilled composite spin-cast roll is a high nickel-chromium infinite chilled cast iron roll, which is produced by full flushing (overflow method) or centrifugal composite casting process. Its material contains high chromium, nickel and molybdenum alloy elements.

High NiCr indefinite chilled composite spin-cast roll has double chemical, the outside has high tensile strength and the inside is a lower one, the hardness drop is lower, so it has high wear resistance. It is usually used for the finishing mill to roll the final material, to roll the angles, bars, flats and so on.
