Application of Laser Heat Treatment Cladding in Metallurgical Iron and Steel Industry

In the iron and steel metallurgical industry, turbine rotating equipment (crew) is the carrier that provides energy and power. Laser processing technology provides safe, reliable, and quality-improved quality assurance for these major key equipment (units).
  For example, the moving and stationary blades of an axial compressor of a steel company, and the moving and stationary blades of a "tow-two" type TRT unit of a blast furnace turbine have been put into production and operated smoothly and reliably. In addition, all moving and stationary blades of the two units restored by the laser cladding profiling technology can increase the service life by *****0% compared with the new blades originally designed and manufactured. Only these two devices can save the company about **0 more. Million yuan for maintenance funds.

The advantages of laser quenching

Heating and cooling speed, quenching effect is good;
The laser is hardened by heat conduction from the surface and inside, no cooling medium, no pollution to the environment.
Self-tempering process, no need to temper, process is simple;
Only heating the surface, the overall performance of the workpiece is not affected;
Heating parts can be precisely controlled and easy to automate production;
Specially designed light guide system can be used for quenching deep holes, inner holes, grooves, blind holes, etc.
In the industrial field, traditional processes such as induction hardening and chemical heat treatment are gradually being replaced.

Device Configuration:
1. High-power *0kW CO2 cross-flow laser and *0,**0 kcal chillers set one by one
2. Five-axis and four-linked laser processing machine, Siemens **2D CNC system
3. It is equipped with an integrating mirror to make the light spot uniform to satisfy the function of laser hardening heat treatment.
4. With powder feeding device to meet the laser cladding function
 

Commen laser cladding materials

At present, the common laser cladding materials are mainly thermal spray welding and thermal spraying materials, including self fluxed alloy materials, carbide dispersion or composite material, ceramic material, etc.
Base material including steel, aluminum alloy, copper alloy, nickel alloy and titanium alloy, etc. As a result of the laser cladding layer dilution rate is low, its performance depends on the general performance of the adopted cladding material.

Laser cladding process
The method of laser cladding in cladding material supply is divided into two kinds, namely the preset laser cladding and synchronization
