Several typical applications of laser cladding processing technology

Views:0     Author:hu     Publish Time: 2021-08-21      Origin:dapeng

The scope of application and application fields of laser cladding processing technology is very wide, covering almost the entire machinery manufacturing industry, including mining machinery, petrochemicals, electric power, railways, automobiles, ships, metallurgy, medical equipment, aviation, machine tools, power generation, printing, Packaging, mold, pharmaceutical and other industries.


1. Manufacturing and remanufacturing of mining equipment and its parts


Coal mining machinery equipment is used in large quantities and wears quickly. Due to its harsh working environment, the parts and components are damaged at a relatively fast speed. The company's main business in laser manufacturing and remanufacturing of coal mining equipment parts include: three machines and one machine


(1) Shearers: main frame, rocker arms, gears, gear shafts, various bushes, articulated frames, cylinders, cylinder seats, guide shoes, sprockets, pin rail wheels, drive wheels, picks, etc.


(2) Roadheader: cylinders, brackets, shafts, various bushes, picks, etc.


(3) Scraper conveyor: middle chute, transition groove, gear box, gear, gear shaft, spiral bevel gear, shaft parts, etc.


(4) Hydraulic supports: hinged holes for cylinders, bases and supports, various bushings, etc.

2. Manufacturing and remanufacturing of power equipment and its parts


Power equipment is distributed in a large amount and runs uninterruptedly, and its parts have a high probability of damage. Steam turbine is the core equipment of thermal power generation. Due to the special working conditions of high temperature and heat, it is necessary to repair damaged unit parts, such as main shaft diameter and moving blades, on a regular basis every year. Gas turbines are often damaged due to their working under high temperature conditions as high as 1300°C. Using laser remanufacturing technology to repair all its defects and restore its performance, the cost is only 1/10 of the price of the new unit.

3. Manufacturing and remanufacturing of petrochemical equipment and its parts


The modern petrochemical industry basically adopts a continuous mass production mode. During the production process, the machine works in a harsh environment for a long time, resulting in damage, corrosion, and abrasion of the components in the equipment. Among them, the parts that often cause problems include valves. , Pumps, impellers, large rotor journals, roulettes, bushings, bushings, etc., and these components are very expensive, and there are many types of parts involved. Most of the shapes are complex and it is difficult to repair, but Because of the emergence of laser cladding technology, these problems are not a problem.

4. Manufacturing and remanufacturing of railway equipment and its parts


With the rapid development of social and economic growth in railway transportation, the demand for new railway vehicles is very large, and the number and performance requirements of main components are also increasing. As a new resource reuse technology, remanufacturing technology can be applied to the remanufacturing of wearable parts of vehicles. Laser surface strengthening is the core technology and process means of remanufacturing, and laser surface cladding technology can be applied to repair and strengthen the surface of remanufactured parts.


5. Remanufacturing of key parts and components of other machinery industry equipment


Remanufacturing of key parts and components in other machinery manufacturing industries, including metallurgy, petrochemical, mining, chemical, aviation, automobiles, ships, machine tools, etc., for the wear and tear of precision equipment, large equipment, and valuable parts in these fields , Eroded and corroded parts, use laser cladding processing technology for repair and performance optimization.
