Import Centrifugal Casting Rolls — Buy in Bulk from Supplier in China

Sinya International Trade Co., Ltd supplies centrifugal casting rolls from its facility in Tangshan, Hebei, China. The rolls can be fabricated from alloy steel, alloy iron or ductile iron according to the client’s engineering drawing. All products are manufactured to GB, AISI, SAE and ASTM/ASME standards and the hardness as well as chemical composition are adjusted to the buyer’s specifications. Inspection is carried out by ultrasonic testing and micro‑structure analysis, and the finished rolls are packed in a steel frame for shipment.

Typical alloy‑steel rolls are offered in grades such as 4140 or 4340, with a hardness range of 250‑350 HB and a dimensional tolerance of ±0.5 mm. Ductile iron rolls commonly meet EN‑1563 class 35‑45, providing good wear resistance for continuous casting lines. In the casting industry, roll diameter and surface finish are critical for product consistency, and suppliers usually provide a surface roughness of Ra ≤ 1.6 µm as a standard. Suppliers often apply a heat‑treatment process such as carburising or nitriding to achieve the required surface hardness.

These rolls are typically purchased by steel foundries, automotive component manufacturers and heavy‑equipment makers that require precise thickness control.
