Recently, the reporter learned from Taishan Xinrong Metal Products Co., LTD., a leading manufacturer of wear-resistant materials in the industry, that the company has made a series of important progress in the research and development and production process of low alloy wear-resistant cast steel parts. Through the optimization of material formulas and the innovation of casting processes, its new generation of products not only maintain excellent wear resistance but also significantly reduce production costs and energy consumption, providing more competitive key component solutions for the "strengthening and improving" of heavy equipment such as mining machinery, cement and building materials, and construction machinery in China.

The exquisite balance between performance and cost

Low alloy wear-resistant cast steel, due to its optimal balance among wear resistance, toughness and economy, has always been an important material choice in wear conditions. However, traditional techniques often encounter challenges such as reduced toughness or rising alloy costs when enhancing hardness and wear resistance.

After long-term research and development, the technical team of Taishan Xinrong Metal has successfully developed an innovative technology system based on multi-element microalloying and precise heat treatment. This technology, by precisely controlling the addition and interaction of trace alloying elements such as vanadium, niobium and titanium, combined with a unique graded quenching and tempering process, forms fine, uniform and tough carbides and matrix structures inside the castings.

Our goal is not to pursue extremely high hardness alone, but to achieve the optimal combination of hardness, toughness, processability and cost. The company's technical director introduced, "The surface hardness of the new generation of low-alloy wear-resistant cast steel parts can stably reach HRC 45-55, and the impact toughness is more than 20% higher than that of conventional products. Meanwhile, by reducing the reliance on precious metal elements, the material cost has been effectively controlled."

Innovative processes drive green manufacturing

In addition to the breakthroughs in materials themselves, Taishan Xinrong Metal has also implemented the concepts of innovation and green development throughout the entire casting process. The 10-ton-per-hour resin sand regeneration treatment system put into use by the company has achieved efficient recycling of molding sand and significantly reduced the discharge of solid waste. By integrating advanced smelting and control technologies, the energy consumption and material loss in the production process have been further reduced.

From new material design to waste recycling, we are building a more environmentally friendly and efficient closed-loop production model. The company's production director stated, "This not only responds to the national call for green manufacturing, but also brings a more stable supply chain and more environmentally friendly product options to downstream customers."

The market application prospects are broad

With its outstanding cost performance and reliability, the low alloy wear-resistant cast steel parts of Taishan Xinrong Metal have been widely used in various vulnerable components such as jaw crusher tooth plates, hammer crusher hammer heads, excavator bucket teeth, liners, and grinding rollers. Several long-term cooperative equipment manufacturers have reported that after using this series of products, the continuous operation time of the equipment under harsh working conditions has been significantly extended, the frequency of maintenance shutdowns has decreased, and the overall operating costs have effectively dropped.

The general manager of the company stated, "As a national high-tech enterprise recognized, we have always regarded technological innovation as the core driving force." At present, the company holds 16 valid utility model patents, most of which focus on the performance improvement and process optimization of wear-resistant materials. In the future, we will continue to focus on the cutting-edge research and development of high-performance wear-resistant materials, closely cooperate with partners in the industrial chain, and jointly promote the advancement of China's heavy equipment manufacturing industry towards greater efficiency, durability and sustainability.

Industry insiders analyze that as the country continues to promote infrastructure construction and efficient resource utilization, the market demand for high-performance wear-resistant parts will continue to grow. Wear-resistant material enterprises represented by Taishan Xinrong Metal, through continuous technological iteration and process innovation, are contributing indispensable "hardcore" forces to enhancing the overall lifespan and reliability of Chinese equipment and reducing the logistics and resource development costs of the entire society.
