Dulbert Hard Rock Cutting Wear-Resistant Pick

In the field of mining and tunnel excavation, as a core consumable, the performance of cutting picks directly affects operational efficiency and costs. The Duerbote U135 roadheader cutting pick stands out in the market and has won repeated purchases from numerous customers. What is the secret behind this?

1. Excellent Materials Lay a Solid Foundation

The Duerbote U135 roadheader cutting pick is extremely stringent in material selection. The pick body is made of high-quality 42CrMo alloy steel, which offers high strength, good hardenability, excellent toughness, minimal quenching deformation, and maintains high creep and persistent strength even in high-temperature environments. In complex and harsh excavation conditions, it can effectively resist external impacts, preventing issues such as breakage and bending of the pick body, thereby solidifying the overall reliability of the cutting pick.

The cutting head is made of high-strength tungsten-cobalt alloy, with the wear-resistant layer upgraded to a cemented carbide metallurgical composite material. Tungsten-cobalt alloy itself has high hardness and strong wear resistance, and the addition of the cemented carbide metallurgical composite wear-resistant layer further enhances the cutting head's anti-wear capability. This significantly slows down the wear rate when facing frequent friction from high-hardness rocks, markedly extending the service life of the cutting pick.

2. Mature Craftsmanship Ensures Superior Quality

Duerbote possesses mature production processes. Its cutting pick production equipment uses domestically advanced fully automatic brazing and quenching integrated production lines, with strict control over every step of the process. From the screening of raw materials to the precision control of dimensions during processing, and finally to the quality inspection of the finished product, every step adheres to high standards. This ensures that the quality of the Duerbote U135 cutting pick meets or even exceeds industry production standards, satisfying the stringent demands of customers.

In terms of alloy brazing and quenching technology, Duerbote stands out uniquely. By precisely controlling temperature and time and using high-quality brazing materials, the alloy and pick body achieve a tight bond. In high-temperature environments, the brazing material evenly penetrates the tiny gaps between the alloy and the pick body, forming a strong metallurgical bonding layer that significantly enhances the bonding strength between the two. This not only improves the hardness and wear resistance of the alloy itself but also significantly increases the bonding interface strength between the alloy and the pick body. In practical operations, when facing high-intensity impacts and friction, the alloy part of the Duerbote U135 cutting pick remains firmly embedded in the pick body, reducing the likelihood of cracking or detachment.

3. Adaptive Design Enhances Operational Efficiency

The U135 cutting pick is designed with full consideration of the needs of different working conditions. It features a standard body and a wide flange shoulder design, which provides excellent protection for the pick holder, effectively extending its service life. Additionally, the cutting pick is made of spark-free material, eliminating spark generation during cutting, greatly enhancing the safety of construction operations. This makes it particularly suitable for working environments with high requirements for fire and explosion prevention.

The tooth design is precisely calculated and optimized to adapt to various excavation needs. The rational tooth shape reduces resistance during cutting, improves cutting efficiency, lowers energy consumption, and makes excavation operations more efficient and economical. Whether in coal mine tunnel excavation or engineering tunnel digging, it delivers outstanding performance.

4. Significant Practical Application Results

Numerous practical cases fully demonstrate the strong capabilities of the Duerbote U135 cutting pick. In a coal mine project in Bijie, Guizhou, facing rock layers with a hardness of F7, the customer had previously used cutting picks from multiple brands with unsatisfactory results, as the rock caused severe wear on the picks. However, after switching to the Duerbote U135 cutting pick, its excellent hardness and toughness, achieved through high-quality alloy steel materials and special heat treatment processes, became evident. In practical application, this model of cutting pick demonstrated an ultra-long service life and stable drilling performance, significantly improving excavation speed and reducing replacement frequency. Customer feedback indicated that under the same working conditions, the service life of the Duerbote U135 cutting pick was extended by over 30% compared to other brands.

In a coal mine in Sichuan, where a well-known domestic brand of cutting pick was previously used for sandstone excavation, frequent alloy breakage occurred, severely affecting excavation progress and costs. After the Duerbote U135 alloy bean cutting pick was put into use, the problem of alloy breakage was completely resolved. Its specially proportioned cemented carbide cutting head and high-strength alloy steel pick body, treated with mature heat treatment processes, are tightly bonded and perform excellently when facing high-intensity impacts and friction from sandstone. According to statistics from the coal mine, after using Duerbote cutting picks, excavation efficiency increased by approximately 30%, equipment downtime was significantly reduced, and overall costs decreased by about 25%.

5. Comprehensive Service Provides Assurance

Duerbote not only provides customers with high-quality cutting pick products but also offers a comprehensive service system. The company has a professional technical team capable of providing full technical support and customized solutions based on different working conditions, ensuring that customers receive timely and effective assistance during use.
