In the wear-resistant field of industrial production, it is often difficult to balance the “hardness” and “toughness” of materials—extremely hard materials tend to be brittle and prone to cracking, while materials with good toughness lack wear resistance. However, the composite material of high manganese steel inlaid with titanium carbide (TiC) perfectly integrates the ultra-high hardness of TiC with the excellent toughness of high manganese steel, successfully addressing this long-standing pain point in the industry.
Taking molten high manganese steel as the matrix, this composite material firmly embeds titanium carbide alloy rods or particles into the working surface via the insert casting process, forming a metallurgical bond. It not only retains the impact resistance and deformation resistance of high manganese steel, but also boasts the ultra-high wear resistance of TiC (up to HV3200 hardness level), making it a “wear-resistant powerhouse” under severe abrasive working conditions. Its application scenarios are mainly concentrated in industries with stringent requirements for wear-resistant components, such as mining, cement building materials, and metallurgy, which can be specifically categorized into the following core scenarios:
I. Mining: The “Hardcore Workhorse” for Crushing Hard Ores
The mining industry is the primary application field of high manganese steel inlaid with titanium carbide. Whether in open-pit mines or underground mines, the wear-resistant components of ore-crushing equipment are constantly subjected to dual challenges of high-intensity impact and severe abrasive wear. Traditional high manganese steel components usually have a very short service life; frequent replacements not only increase costs but also severely disrupt production efficiency. In contrast, the composite wear-resistant components inlaid with titanium carbide are perfectly suited to such harsh working conditions.
This composite material is most widely used in the core components of crushers. Typical applications include jaw plates and tooth plates of jaw crushers, concave and mantle of cone crushers, hammers of hammer crushers, and blow bars of impact crushers. For example, when crushing high-hardness ores such as granite and basalt, the service life of titanium carbide-inlaid hammers is 3–8 times longer than that of ordinary high manganese steel hammers, while the service life of jaw plates and concave/mantle can be extended by more than 2–5 times.
Jiangxi Copper Corporation once adopted this technology to develop wear-resistant liners for waste rock belt discharge hoppers and tooth plates for jaw crushers, all of which saw their service life doubled, significantly reducing operation and maintenance costs. In a certain iron ore application case, the utilization rate of the cone crusher unit equipped with titanium carbide composite liners reached 90.3%, saving 410,000 yuan in annual maintenance costs and remarkably improving the overall equipment efficiency. In addition, this composite material also delivers excellent wear-resistant performance in mining components such as liners for semi-autogenous mill feed trolleys and wear plates for apron feeders.
II. Cement & Building Materials: The “Wear-Resistant Mainstay” in Grinding and Crushing Processes
Throughout the cement production process—from limestone mining and raw material crushing to clinker grinding—wear-resistant components play an indispensable role. In particular, raw materials like limestone and quartzite have high hardness, causing severe wear to equipment. Thanks to its outstanding wear resistance, high manganese steel inlaid with titanium carbide has become an ideal choice for the cement industry.
In the raw material crushing stage, blow bars of impact crushers and hammers of hammer crushers are generally made of this composite material, which can effectively handle the impact crushing requirements of large limestone blocks and reduce the hassle of frequent component replacements. In the grinding stage, the grinding rollers and mill disc liners of vertical mills are core wear-resistant components that bear long-term material extrusion and grinding. After adopting the high manganese steel inlaid with titanium carbide material, not only is the wear resistance greatly enhanced, but also the grinding efficiency and product quality stability are improved.
The high manganese steel inlaid rod sleeves produced by Zhejiang Yurong Industrial Co., Ltd., which embed titanium carbide alloy rods into a high manganese steel matrix, are suitable for grinding various materials and feature excellent wear resistance, strong material handling capacity, and low maintenance costs. In addition, this composite material can also effectively extend the service life of equipment in scenarios such as sand and gravel crushing equipment at concrete mixing stations and wear-resistant liners in dry-mix mortar production.
III. Metallurgical Industry: The “Wear-Resistant Expert” for Handling Harsh Materials
The material handling working conditions in the metallurgical industry are equally harsh. Both the beneficiation and crushing of metal ores and the treatment of metallurgical slag impose high requirements on the wear resistance and impact resistance of wear-resistant components. The application of high manganese steel inlaid with titanium carbide in this field is mainly concentrated in the ore pretreatment stage before smelting and the slag treatment stage after smelting.
In the crushing process of metal ores such as copper, iron, and gold, components like jaw plates of jaw crushers and concave of cone crushers made of this composite material can effectively resist severe ore wear, ensuring the continuous and stable operation of the crushing process. The successful application of this material in the jaw crusher tooth plates at Guixi Smelter of Jiangxi Copper Corporation serves as a typical case in the metallurgical industry. In addition, in the crushing and recycling stage of metallurgical slag, hammers and liners of double-rotor crushers made of this composite material can withstand the high hardness and high abrasiveness of slag, extending component service life and reducing environmental protection treatment costs.
IV. Other Special Wear-Resistant Scenarios: Niche yet Critical Supplementary Applications
Beyond the above three core industries, high manganese steel inlaid with titanium carbide also plays a role in some niche but critical wear-resistant scenarios. For instance, in the flue gas desulfurization systems of power plants, the liners of limestone slurry transportation and grinding equipment are subjected to long-term dual erosion from corrosive media and abrasives. This composite material not only resists wear but also has a certain degree of corrosion resistance, effectively extending equipment service life. In the quartz sand production industry, after adopting this composite material for the roll rings of roll crushers, the quartz sand crushing efficiency and product quality are improved, while the wear rate and replacement frequency of roll rings are reduced.
Summary: Adapting to Core Working Conditions of “High Impact & High Wear”
Essentially, the application scenarios of high manganese steel inlaid with titanium carbide all revolve around the core working conditions of “high impact and high wear”. Whether it is the crushing of hard ores in mining, the raw material grinding in the cement industry, or the material handling in the metallurgical industry, wherever severe abrasive wear and impact loads exist, this composite material can leverage its dual advantages of “hardness + toughness” to replace traditional high manganese steel components, achieving the goals of extending service life, reducing maintenance costs, and improving production efficiency. With the continuous optimization of composite casting technology, its application scenarios are further expanding, and it is expected to play an important role in more wear-resistant fields in the future.
