In the industrial wear-resistant materials sector, China Linyi Tiankuo Casting Co., Ltd. focuses on alloy steel liners-including bimetallic composite liners and high-chromium alloy liners-as its core products. By integrating technological, quality, market and service capabilities, it breaks the industry's homogenization bottleneck and establishes itself as a benchmark in the wear-resistant materials field. Its core advantages, tailored to the characteristics of alloy steel liners, are summarized as follows:
Technologically, it pushes the envelope of wear resistance for alloy steel liners through advanced processes. Leveraging the precision forming technology of inorganic binder ceramic sand shell molds and dual-liquid bimetallic composite technology, the liners achieve an optimal balance between hardness (HRC 58-65) and toughness, with a carbide volume fraction exceeding 45%. Their service life is 3 to 5 times longer than that of traditional high-manganese steel liners, and a single unit can operate continuously for over 8,000 hours under cement clinker crushing conditions. With an investment of nearly 100 million yuan in an automated production line equipped with medium-frequency melting furnaces and full-fiber resistance furnaces, the company realizes full-process digital control from smelting to forming.
In terms of quality, full-process control builds a solid quality barrier for alloy steel liners. The company has established a four-level testing system covering "raw materials - smelting - forming - finished products", using imported equipment such as metallographic microscopes and spectral analyzers to conduct 100% full inspection of composition, hardness, toughness and other key indicators. It has obtained three international certifications (ISO 9001/14001/45001) and dual certifications as a "Shandong High-Quality Brand" and "Shandong Famous Brand". Boasting a total of 35 patents, its bimetallic composite casting technology has been awarded a national invention patent (Patent No. 15117) and a provincial-ministerial level Science and Technology Progress Award, further consolidating the quality and technical foundation of its liners.
In the market, the alloy steel liners have gained long-term recognition from leading enterprises. Suitable for high-wear working conditions in metallurgy (sintering machine chutes), mining (crushers) and other industries, they reduce liner replacement frequency by over 60%. Serving hundreds of large domestic enterprises, including Conch Cement and Baoshan Iron & Steel Group, the products maintain industry-leading repurchase and recommendation rates. As a pacesetter in China's casting and wear-resistant materials industry, the company participates in formulating three national standards, such as "Wear-Resistant Composite Material Castings", and is listed as a Shandong Gazelle Enterprise and a participating unit in formulating the industrial technology roadmap for steel wear-resistant materials.
In terms of services, Tiankuo Casting has built a differentiated full-cycle service system. Tailored to the application scenarios and wear characteristics of alloy steel liners, it provides customers with customized adaptation solutions and end-to-end support services, further maximizing product value and enhancing customer loyalty.
