Interpretation of the abrasion and corrosion resistance of hydraulic support columns

The pillar is a key component of the hydraulic support. Because there is a lot of corrosive media downhole, and it is easy to be hit by splashing coal gangue, which seriously affects the service life of the piston rod. Post repair has gone through the era of electroplating, but because of the high environmental pollution and serious carcinogenicity of this process, this process is gradually being eliminated. The cleanliness of laser cladding energy and its high performance are gradually being recognized by major coal manufacturers.

What is the remanufacturing of abrasion and corrosion resistance for hydraulic support columns?

The so-called remanufacturing of hydraulic support columns is the production process of recovering discarded or about to be discarded columns, and using professionally developed laser cladding technology and equipment to carry out professional and batch repairs. After remanufacturing, the performance of the middle cylinder and movable column far exceeds the quality and performance of the new product. It is a high-level form of "recycling" of the circular economy.

The new technology for strengthening and repairing the piston rod of the hydraulic support created by Aigang has the advantages of high automation, low cost, excellent abrasion resistance and corrosion resistance, and it has responded well to the national call for energy conservation and emission reduction.

How to remanufacture the abrasion and corrosion resistance of hydraulic support columns?

Laser remanufacturing and repairing process of the cylinder and column of the hydraulic support: workpiece surface cleaning → rough turning to remove fatigue layer → professional cleaning of the surface to be cladding → laser cladding → color inspection → defect repair → fine car cladding surface → fine grinding surface → polishing → Finished product inspection → Packing and delivery.

Why choose Aigang Remanufacturing?

Advantage
