Benxi Liaoye Roll Co., Ltd. is located in Benxi Manchu Autonomous County, Liaoning Province, enjoying outstanding location and resource advantages. It is a leading manufacturer in the professional roll production industry. Benxi County has a superior geographical position and a well-developed transportation network. The Shendan Expressway and Benhuan Highway run through the region, placing it within the one-hour economic circle of Shenyang. It is 100 km from the provincial capital Shenyang, 85 km from Taoxian International Airport, 160 km from Dandong Port, and 230 km from Yingkou Port, enabling efficient domestic and international connectivity. The company is adjacent to Tianshifu Railway Station, the terminal of the Xitian Railway line, only one kilometer away, with ample railway transport capacity that significantly reduces long-distance freight costs and provides solid logistics support. Moreover, Benxi County is rich in mineral resources. Its iron ore is naturally low in phosphorus and sulfur, and the locally produced "Ginseng Iron" is renowned in the industry—the sulfur and phosphorus content in the pig iron is controlled below 0.03%, providing an excellent raw material foundation for roll production.
The company recognizes the importance of advanced equipment to product quality. Recently, it invested more than 10 million RMB in a plant expansion project to strengthen production hardware, optimize production layout, and expand production scale, providing ample room for future capacity enhancement and product structure upgrading. The introduction of the core 84160 CNC grinding machine has significantly improved roll grinding accuracy and efficiency, better meeting the processing requirements for high-precision rolls. In addition, the company is equipped with a complete set of advanced casting, heat treatment, machining, and inspection equipment. The foundry uses electromagnetic suction feeding, electronic scale metering, automatic temperature measurement, and medium-frequency induction furnace melting to precisely control molten steel (or iron) composition, ensuring sufficient overheating and uniform temperature. The heat treatment process uses bogie-type resistance furnaces with automatic temperature curve control to ensure uniform and stable furnace temperature. The machining workshop has large 2.5-meter 180 lathes, 2-meter 125 CNC lathes, and various other precision machine tools, covering turning, milling, planing, grinding, drilling, slotting, and wire cutting, strictly controlling the tolerances and surface finish of all parts of high-precision rolls. At the same time, the company has comprehensive inspection means, covering dimensional inspection, chemical composition inspection, hardness inspection, ultrasonic flaw detection, and metallographic inspection, providing layered quality control.
As a professional roll manufacturer, the company has an annual roll output of 20,000 tons and an extremely rich product range, covering chilled cast iron, indefinite chilled cast iron, martensitic, pearlite nodular iron, bainite nodular iron, high-chromium cast iron, high-speed steel, high-boron cast iron, high-chromium cast steel, alloy cast steel, alloy semi-steel, Cr3–Cr5 backup rolls, and other materials, meeting diverse needs in different scenarios. With unique technologies for many products, the company's products have won high recognition and praise from numerous domestic hot rolling enterprises, with sales covering more than 20 provinces across China. It is worth noting that the company pays close attention to the individual characteristics and requirements of each rolling mill, customizing roll process design for the operating conditions of each stand to ensure perfect matching between products and mill characteristics.
Innovation drives enterprise development. The company is a technology-based SME. In March 2025, it was officially recognized as a high-tech enterprise (Certificate No.: GR202421002625), and in 2026 it was rated as a specialized, refined, distinctive, and innovative enterprise, with a total of 15 authorized patents. The company actively cooperates with domestic materials research institutes, tracks cutting-edge achievements in metal materials technology, promotes the implementation of new technologies and processes in production, and continuously improves product performance and core competitiveness.
The company attaches great importance to the research, development, and promotion of new products, actively carrying out in-depth cooperation with many domestic materials research institutes, closely tracking the latest scientific and technological achievements in the field of metal materials science, promptly applying technological means beneficial to improving roll performance to production practice, and continuously enhancing core competitiveness. The company always takes continuously improving product quality as its purpose, serving customers as its core philosophy, and building a Chinese boutique roll production base as its mission.
All Liaoye people pursue excellence, striving for perfection in every process detail. Relying on the raw material advantage of Benxi "Ginseng Iron", we are committed to providing our customers with the highest quality roll products and services.

Full-Process Inspection for Chemical Composition, Hardness, Internal Defects, and Metallographic Structure
An atomic emission spectrometer that rapidly and accurately analyzes the chemical composition of metallic materials, providing a reliable basis for smelting composition control.
A hardness testing instrument that measures a material's resistance to indentation by a hard object. It is one of the important performance indicators of metallic materials; generally, higher hardness means better wear resistance.
A portable industrial non-destructive testing instrument capable of rapidly, conveniently, non-destructively, and accurately detecting, locating, evaluating, and diagnosing various internal defects (cracks, porosity, blowholes, inclusions, etc.) in workpieces.
Perfectly combines optical microscopy, photoelectric conversion, and computer image processing technologies, enabling metallographic image observation on a computer, as well as analysis, grading, output, and printing of metallographic images.
