Import Heat Resistant Casting Alloy Furnace Roller — Buy in Bulk from Supplier in China

The heat resistant casting alloy furnace roller supplied by Hexin Thermoprocess Equipment Co., Ltd. is offered with an outer diameter (OD) range of 50 mm to 1 600 mm and is produced by centrifugal casting of the barrel. The supplier lists a wide selection of alloy grades including 24/24NbTZ, G18/8NiCr, 28Cr/48Ni/5W, 25Cr/20Ni, 24/24NiCrNb (1.4855), 25Cr/35Ni (1.4852), 38Ni/18Cr (1.4865) as well as specialised alloys 2.4633 and 2.4879, all designed for high temperature service. Working temperatures average between 800 °C and 1 200 °C, and the rollers are compatible with forged shafts made from 310 stainless steel, EN8 or EN24.

These rollers combine heat‑resistance, corrosion resistance and wear resistance that are typical requirements for steel‑mill furnace applications. The alloys normally achieve a hardness of HRC 45‑55 and a surface roughness of Ra ≤ 1.6 µm, which aligns with industry expectations for continuous annealing and galvanising lines. Hexin applies strict quality control, performing chemical analysis by spectrometer, mechanical testing at ambient and elevated temperatures, ultrasonic, X‑ray, dye‑penetrant, boroscope, eddy‑current and pressure tests to verify each batch.

Primary users are steel manufacturers operating continuous annealing lines (CAL) or continuous galvanising lines (CGL) that need reliable furnace rollers. Hexin can customise the material grade or shaft dimensions on request, but exact minimum order quantities, lead times and payment terms are not disclosed in the listing and should be confirmed directly with the supplier. Interested importers are encouraged to contact the company for a quotation and to discuss any special certification or packaging requirements.

Hexin Thermoprocess Equipment Co., Ltd. is located in Xinqiao Town, Jingjiang, Jiangsu Province, China.
