Cone Crusher Liner

Titanium Carbide (TiC) Alloy Solid Solution Strengthening (Core Patent)

Reinforcement Phase: TiC titanium carbide (hardness Hv 3200, melting point 3140°C) integrated with matrix via proprietary cast-inlay metallurgical bonding process

Alloy System: 30+ elements including rare earth (Ce, La), niobium (Nb), molybdenum (Mo), vanadium (V), nickel (Ni), chromium (Cr) added to optimize interface chemistry

Microstructure: Dispersion-strengthened solid solution phase with TiC particles (5-50μm) uniformly distributed in austenitic matrix, creating composite strengthening effect

Performance: Wear resistance is 2 times that of TM52 market standard products. The TiC phase provides hard particle protection while the tough matrix absorbs impact energy

Intellectual Property: Original core technology patented by Shandong Hengtai Intelligent Manufacturing

High Manganese Steel Matrix Solid Solution Strengthening

Purification Technology: Multiple rare earth elements added during molten steel smelting (EBT-LF-VD process), achieving sulfur (S) and phosphorus (P) content at only half of industry average—significantly improving cleanliness and toughness

Chromium Enhancement: Cr content increased by adding stainless steel scrap to base melt:
• Mn18Cr2: C 1.0-1.4%, Mn 17-19%, Cr 1.5-2.5%, Ni 0.3-0.8%
• Mn22Cr2: C 1.0-1.4%, Mn 21-23%, Cr 2.0-3.0%, Ni 0.5-1.0%

Bonding Improvement: The optimized matrix composition increases metallurgical bonding strength between high manganese steel and TiC alloy by 6 times vs conventional cast-inlay methods

Fracture Prevention: Effectively eliminates TiC alloy:
• Shedding (interface debonding)
• Brittle fracture (stress concentration cracking)

ROI Calculation Example: For a 300 t/h aggregate plant processing granite, switching from ordinary Mn18Cr2 (2000 hrs life) to Hengtai TiC-Mn18Cr2 (4000 hrs life) saves approximately 6 liner changes per year. At 8 hours downtime per change and $500/hour lost production value, annual savings exceed $24,000—paying back the 30% price premium within 3 months.

Q1: What is a dual-solid solution strengthened cone crusher liner?

It is a high-end wear-resistant liner compounded by two core technologies: titanium carbide (TiC) alloy solid solution strengthening and high manganese steel matrix solid solution strengthening. The TiC phase (hardness Hv 3200) is metallurgically bonded with Mn18Cr2/Mn22Cr2 matrix containing 30+ alloy elements (rare earth, niobium, molybdenum, vanadium, nickel, chromium). This creates a dispersion-strengthened composite that is significantly superior to traditional liners in wear resistance, impact resistance and service life.

Q2: What is the core advantage of dual-solid solution strengthening technology?

While maintaining the excellent toughness of high manganese steel (ak >150 J/cm²), the technology introduces the super wear resistance of titanium carbide alloy (TiC). The dual-solid solution structure achieves: (1) 2x wear resistance vs TM52 market standard; (2) 6x stronger bonding strength between TiC and matrix vs conventional cast-inlay; (3) Complete elimination of TiC shedding and brittle fracture problems; (4) 20%+ longer comprehensive service life vs ordinary cone crusher liners.

Q3: How much is the service life improved compared with ordinary Mn18Cr2 cone liners?

Under identical working conditions (granite crushing, 150-200 MPa compressive strength): Cast-inlay TiC Mn18Cr2 Cone Liner achieves approximately 2.0 times the service life of ordinary Mn18Cr2 liners (typically 4000-6000 hours vs 2000-3000 hours). Cast-inlay TiC Mn22Cr2 Cone Liner achieves approximately 2.2 times the service life of ordinary Mn22Cr2 liners (typically 5000-7000 hours vs 2500-3500 hours). Actual life depends on feed size, CSS setting, and material abrasiveness.

Q4: Is the TiC alloy layer prone to shedding or brittle fracture?

No. Through our proprietary high manganese steel solid solution strengthening process, the metallurgical bonding strength between TiC and the matrix is increased by approximately 6 times compared to conventional mechanical embedding. The 30+ alloy elements (including rare earth, Nb, Mo) create a gradual transition zone at the TiC-matrix interface, eliminating stress concentration. Our liners maintain complete structural integrity under long-term high-impact working conditions (crushing forces >300 MPa) without any shedding or brittle fracture.

Q5: What types of cone crushers is it suitable for?

Our cone crusher liners are suitable for all types: single-cylinder hydraulic cone crushers (GP/HP series), multi-cylinder hydraulic cone crushers (HPM series), compound cone crushers (Symons 2FT-7FT), spring cone crushers, and gyratory crushers. We support OEM customization for domestic Chinese brands and international brands including Metso (Nordberg), Sandvik, Terex, Telsmith, and others. Send us your crusher model or original part number for precise matching.

Q6: What materials are suitable for crushing with this liner?

Our TiC-insert cone crusher liners are especially suitable for medium and high hardness, high-abrasive materials including: granite (compressive strength 150-250 MPa), basalt (200-350 MPa), iron ore (magnetite/hematite, 250-400 MPa), quartzite (200-300 MPa), diabase, andesite, copper ore, gold ore, and other metal ores. Also ideal for continuous crushing operations under high-impact, high-wear conditions where ordinary Mn18Cr2 liners fail prematurely.

Q7: How does it compare with common TM52 wear-resistant cone liners on the market?

Under identical working conditions, our dual-solid solution strengthened cone liner demonstrates approximately 2 times the wear resistance of TM52 products. Key differentiators: (1) TM52 uses simple mechanical embedding of wear blocks, while our TiC forms true metallurgical bonding; (2) Our 30+ alloy element system provides superior matrix strengthening vs TM52's basic composition; (3) Our S/P content is only half of TM52, ensuring higher purity and toughness; (4) Lower fracture risk due to optimized stress distribution at reinforcement-matrix interface.

Q8: What is the price difference vs ordinary cone crusher liners?

Our TiC-insert cone crusher liner price is approximately 1.3 times that of corresponding base material (Mn18Cr2/Mn22Cr2) liners. However, the service life is more than 2 times longer, resulting in: (1) 35% lower unit crushing cost per ton; (2) 50%+ reduction in downtime for liner changes; (3) Lower labor and maintenance costs; (4) Improved overall line operation efficiency. The total cost of ownership (TCO) is typically 30-40% lower than using ordinary liners over a 2-year period.

Q9: Is it suitable for high-intensity continuous operation?

Very suitable. Our liners are specifically engineered for high-wear, high-impact, 24/7 continuous operation conditions. The dual-solid solution structure maintains performance stability at elevated temperatures (up to 150°C surface temp) and under cyclic loading. Typical applications: large-scale mining operations (copper, iron, gold), high-capacity aggregate plants (300-1000 t/h), and construction material production requiring minimal shutdown. The extended service life significantly reduces replacement frequency from monthly to bi-monthly or quarterly.

Q10: Does it support customization and export projects?

Yes, full customization is supported. We manufacture according to: (1) Equipment drawings and models; (2) Original OEM part numbers; (3) Physical samples for reverse engineering; (4) Specific working conditions and material characteristics. Our liners have been exported to mining operations and aggregate plants in Chile, Peru, Brazil, Turkey, UAE, Saudi Arabia, Indonesia, Philippines, South Africa, and other countries. Typical delivery: 20-35 days for standard models, 35-50 days for custom designs. Minimum order: 1 set (mantle + bowl liner) for trial orders.
