Company Profile

Benxi Jingtang Rolls Co., Ltd. Plant

Benxi Jingtang Rolls Co., Ltd. is located in the scenic Benxi Manchu Autonomous County, Liaoning Province. Benxi County enjoys a superior geographical position and convenient transportation: the Shendan Expressway and Benhuan Highway run through the region, placing it within the one-hour economic circle of Shenyang. The county seat is 100 km from Shenyang, the provincial capital, 85 km from Taoxian International Airport, 160 km from Dandong Port and 230 km from Yingkou Port. The company is only one kilometer from Tianshifu Railway Station, the terminus of the Xitian Railway line, with ample railway transport capacity that greatly reduces long-distance freight costs. Benxi County is also rich in mineral resources; its iron ore is naturally low in phosphorus and sulfur, and the pig iron produced is of excellent quality with sulfur and phosphorus contents both controlled below 0.03%, renowned as "Ginseng Iron".

Relying on the "Ginseng Iron" production base, the company adopts a short-process approach by directly introducing molten iron at high temperature into the roll production workshop, where it is heated and alloyed in medium-frequency furnaces before pouring. This achieves energy savings and environmental protection while producing premium rolls with excellent comprehensive mechanical properties, thermal fatigue resistance and accident resistance.

The company is equipped with a complete set of casting, heat treatment, machining and inspection facilities. The foundry uses electromagnetic suction feeding, electronic scale metering, automatic temperature measurement and medium-frequency induction furnace melting, ensuring precise molten steel (or iron) composition with sufficient overheating and uniform temperature. Heat treatment uses bogie-type resistance furnaces with automatic temperature curve control and uniform furnace temperature. The machining workshop is equipped with various machine tools including large 180 lathes and 125 CNC lathes, covering turning, milling, planing, grinding, drilling, slotting and wire cutting, ensuring the tolerance and surface finish requirements of all parts of high-precision rolls. The company also has comprehensive inspection means, covering dimensional inspection, chemical composition inspection, hardness inspection, ultrasonic flaw detection and metallographic inspection.

The company is a professional roll manufacturer with an annual output of 20,000 tons. Its product range covers chilled cast iron, indefinite chilled cast iron, pearlite nodular iron, bainite nodular iron, high chromium cast iron, high-speed steel, alloy cast steel, alloy semi-steel, Cr3-Cr5 backup rolls and other hot-rolling mill roll materials.

The company has unique technologies for many products, and its products have won recognition and praise from numerous domestic hot-rolling enterprises, with sales covering more than 20 provinces across China. 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 with mill characteristics.

Jingtang attaches great importance to the research, development and promotion of new products, cooperating with many domestic materials research institutes and closely tracking the latest scientific and technological achievements in the field of metal materials science, promptly applying technological means beneficial to roll performance improvement to production practice.

Jingtang pursues perfection in every process detail and excellence in production management. With the advantage of premium Benxi "Ginseng Iron" raw materials and the efforts of all Jingtang people, the company is committed to building China's fine roll production base and providing customers with the highest quality rolls.
