Twin-Screw Scraper Conveyor Laser Cladding Repair Processing

As an important material conveying equipment in industries such as coal mining and metallurgy, the Shuanglong scraper conveyor's operational stability and reliability are crucial for the smooth operation of the entire production line. However, due to long-term operation in harsh environments, scraper conveyors often face issues such as wear and corrosion, which not only affect the equipment's operational efficiency but may also lead to safety incidents. Therefore, timely and effective repair and processing of the Shuanglong scraper conveyor are particularly important. In recent years, laser cladding technology has been widely applied in the field of scraper conveyor repair due to its unique advantages. This article will provide a detailed introduction to the laser cladding repair and processing of the Shuanglong scraper conveyor.

I. Overview of Laser Cladding Technology

Laser cladding technology is a technique that uses a high-energy-density laser beam as a heat source to melt alloy powder or wire of a specific composition, forming a metallurgically bonded coating on the substrate surface, thereby achieving surface modification or repair of materials. This technology offers advantages such as fast heating speed, small heat-affected zone, high bonding strength between the coating and the substrate, and dense coating structure, making it particularly suitable for the surface repair and strengthening of high-precision, high-demand components.

II. Laser Cladding Repair Process for Shuanglong Scraper Conveyor

1. Preliminary Preparation for Laser Cladding Repair of Shuanglong Scraper Conveyor

Before performing laser cladding repair processing, a comprehensive inspection and assessment of the Shuanglong scraper conveyor must be conducted to determine the areas and extent of repair required. At the same time, suitable alloy powder or wire should be selected based on repair needs, and the corresponding laser cladding equipment and auxiliary tools should be prepared.

2. Surface Treatment for Laser Cladding of Shuanglong Scraper Conveyor

The surface of the scraper conveyor requiring repair should undergo cleaning, rust removal, and degreasing to ensure a strong metallurgical bond between the cladding layer and the substrate. Additionally, surface roughness treatment is performed to increase the contact area between the cladding layer and the substrate, enhancing bonding strength.

3. Laser Cladding Repair Processing

The prepared alloy powder or wire is fed into the laser beam through a powder feeder or wire feeding mechanism. The high-energy-density laser beam melts the powder or wire, which is then coated onto the surface of the scraper conveyor. During the cladding process, parameters such as laser power, cladding speed, and powder feed rate must be controlled to ensure the quality and performance of the cladding layer.

4. Post-Processing After Laser Cladding Repair of Shuanglong Scraper Conveyor

After cladding is completed, post-processing such as grinding and polishing is performed on the cladding layer to eliminate surface defects and unevenness, improving the surface quality and aesthetics of the cladding layer. Additionally, necessary inspections and tests are conducted on the cladding layer to ensure it meets usage requirements.

III. Advantages of Laser Cladding Repair Processing for Shuanglong Scraper Conveyor

1. Fast Repair Speed: Laser cladding technology has a fast heating speed, enabling repair processing to be completed in a short time, reducing equipment downtime and improving production efficiency.

2. High Repair Quality: The laser cladding layer forms a metallurgical bond with the substrate, resulting in high bonding strength, excellent wear resistance, corrosion resistance, and other properties, effectively extending the service life of the scraper conveyor.

3. Wide Applicability: Laser cladding technology is suitable for the repair processing of scraper conveyors made of various materials and shapes, particularly for the surface repair and strengthening of high-precision, high-demand components.

4. Environmental Friendliness and Energy Efficiency: Laser cladding technology uses a high-energy-density laser beam as a heat source, offering high heating efficiency and low energy consumption, while also reducing environmental pollution and damage.

IV. Conclusion

Laser cladding repair processing technology for the Shuanglong scraper conveyor is an efficient, high-quality, and environmentally friendly surface repair technology with broad application prospects in industries such as coal mining and metallurgy. With the continuous development and refinement of the technology, it is believed that laser cladding technology will play an even more important role in the field of scraper conveyor repair, providing strong support for the production and development of enterprises.
