“Adamite Rolls” is an industrial product used in metal processing and rolling, especially in the steel manufacturing process.

Material composition

Adamite Rolls are made of alloy cast iron, which contains a high proportion of alloying elements such as chromium (Cr), molybdenum (Mo), and nickel (Ni), making it highly hard and wear-resistant.

The table of adamite rolls chemical composition as follows

Alloy Materials	C	Si	Mn	P	S	Ni	Cr	Mo
ZuB140CrNiMo	1.30~1.50	0.30~0.60	0.70~1.10	≤0.035	≤0.030	0.20~0.80	0.80~1.20	0.20~0.60
ZuB160CrNiMo	1.50~1.70	0.30~0.60	0.70~1.10	≤0.035	≤0.030	0.20~1.00	0.80~1.20	0.20~0.60
ZuB180CrNiMo	1.70~1.90	0.30~1.00	0.70~1.20	≤0.035	≤0.030	0.60~1.50	1.00~1.50	0.20~0.80
ZuB200CrNiMo	1.90~2.10	0.30~1.00	0.70~1.20	≤0.035	≤0.030	1.00~2.00	1.20~2.00	0.20~0.80

Features

High hardness and wear resistance: Due to its special alloy composition, Adamite Rolls can achieve a high level of hardness and excellent wear resistance, making it suitable for long-term, high-intensity rolling processes.
Toughness and strength: Compared with ordinary cast iron rolls, Adamite Rolls have higher toughness and strength, can withstand greater pressure and impact, and reduce the risk of breakage.
Thermal stability: Adamite Rolls exhibit excellent thermal stability in high temperature environments and are not prone to deformation, ensuring dimensional accuracy during rolling.

Applications

Adamite Rolls are widely used in various metal rolling processes, including:

Hot-rolled and cold-rolled steel plates: used for rolling steel plates and strips of various thicknesses.
Rebar and wire rolling: suitable for the production of rebar and wire for construction.
Rolling of non-ferrous metals such as copper and aluminum: It can also be used for rolling of non-ferrous metals to meet their high precision and high finish requirements.

Advantages

Long service life: Due to its high hardness and wear resistance, Adamite Rolls have a long service life, which reduces the frequency of replacement and reduces production costs.
High processing accuracy: It can maintain high precision during the rolling process, effectively improving the quality of the finished product.
Low repair and maintenance costs: Due to its good toughness and durability, Adamite Rolls have a low probability of damage, and the cost of repair and maintenance is relatively low.

Manufacturing process

The manufacturing of Adamite Rolls requires a strict process flow, including smelting, casting, heat treatment and machining steps to ensure that the performance of its final product meets the expected standards and requirements.
