Self-developed formula, achieving outstanding performance
This brand name is the formula independently developed by our company. The content of molybdenum (Mo), vanadium (V), and chromium (Cr) is all higher than the data you listed. Adding these precious alloy elements helps extend the service life of the rolling mill and achieve the best performance. For the advantages brought by each chemical element to the rolling mill, please refer to the attached document “HSS Rolling Mill Composition Characteristics”.
The overall service life of our HSS working rolls can reach 4 times that of cast iron rolls, and the tonnage passed per pass is 3.5 to 5 times that of cast iron rolls. We have been committed to the research and development of HSS rolling mill products for a long time, and the market share of HSS rolling mill products in China alone reaches 70%, while the market share of HSS roll rings is as high as 90%. Therefore, the price we offer you is undoubtedly a highly competitive offer.
Industry-leading, strength testifies
CYKC Group has an annual comprehensive production capacity of 15,000 tons of high-speed steel rolls and roll rings, being the enterprise with the highest market share in the domestic high-speed steel rolls and roll rings market. It is precisely the persistent pursuit of the production process and material research of high-speed steel rolls and roll rings that enables CYKC Group’s high-speed steel rolls and roll ring series to continuously iterate and update, always remaining at the leading level of the industry.
Continuous innovation in materials and processes ensures that CYKC Group’s products have a performance improvement of more than 30% compared to similar products from abroad, with a product usage rate of over 95%, significantly improving the operation rate of steel enterprises, reducing the tonnage of rolls per ton of steel, and reducing energy consumption and worker labor intensity, helping customers reduce costs and increase efficiency.
Professionalism, constantly surpassing
Professionalism is the persistence in upgrading technology and equipment, the pursuit of continuous improvement in product quality, and the implementation of process control in quality management.
To enhance quality, CYKC Grouphas successively invested heavily in introducing advanced production and testing equipment. We have now built 2 casting production lines, 2 heat treatment lines, 2 rolling mill processing lines, and 2 roll ring processing lines. The physical testing center established by the company always adheres to the standards of “the most complete equipment, the optimal function, the highest precision, and the highest personnel quality”, equipped with advanced testing equipment such as direct reading spectrometers, carbon-sulfur automatic analyzers, mobile spectrometers, metallographic microscopes, ultrasonic flaw detectors, universal testing machines, etc., fully ensuring the precise inspection of all physical components of the produced products and purchased raw materials, precise control of product performance, and the ability to customize according to different customer needs.
Centrifugal casting process: Outer layer tough, core strong and resilient
CYKC Group adopts the centrifugal casting process. The outer working layer is HSS. The core is ductile iron. The outer HSS layer provides excellent wear resistance. It also provides excellent thermal hardness. The ductile iron core provides good toughness. This toughness resists impact loads. It also prevents roll breakage.
Based on CYKC Group’s practical experience, for this size of HSS rolls, a 45 mm radial working layer is sufficient. Increasing the working layer thickness will not significantly improve service life. Instead, it will lead to unnecessary cost increases. This judgment is based on a large amount of actual application data from CYKC Group. It reflects our responsibility to customers. It also helps reduce costs and increase efficiency for them.
Quality builds a brand, integrity creates the future

FAQ
Q1: Why are the rolls of CYKC Group more durable than those of other manufacturers?
A: They are made with a self-developed formula, containing higher levels of Mo, V, and Cr. The process uses centrifugal casting. The outer layer is HSS. It is wear-resistant and heat-resistant. The core is ductile iron. It is shock-resistant. The lifespan is four times that of cast iron rolls.
Q2: Is a thicker working layer always better?
A: No. Through practical verification, the 45mm diameter rolls of this size are already sufficient. Thicker does not significantly increase the lifespan; instead, it significantly increases the cost.
Q3: How is the supply capacity?
A: We produce 15,000 tons per year. We have 8 production lines including casting, heat treatment, roll processing, and roll ring processing, ensuring stable supply.
Q4: Is there a price advantage?
A: HSS rolls have a 70% market share in China and roll rings have a 90% market share. Our scale advantage brings highly competitive quotations.
Q5: Can it be customized?
A: Yes. The company can achieve customized production according to different customer needs.
