Roller Surface Hardfacing Machine Getting Wear Resistant Surface , Metallurgical Steel Plant
1. Brief introduction
This set of equipment is mainly used in different kinds of casting roller, hot roller, cold roller, non-ferrous metal roller, whose surface can be protected to maintain a certain degree of hardness. As to the welding type, we often use submerged arc welding (SAW) or open arc welding. The work piece is held by 500 chuck clamping and overturning continues. The passive end is provided with a rotary top position. The operator can operate the machine easily.
2. The main parameters

| 2 | Workpiece axle diameter (mm) | Φ250-500 | 9 | The transverse walk speed (mm/min) | 2-100 |
| 3 | Application of workpiece weight (Tons) | 5 | 10 | The welding head up/down distance by motor (mm) | 350 |
| 4 | Application of workpiece length (mm) | 100-4000 | 11 | Left/Right distance by hand (mm) | 100 |
| 5 | Jaw chuck | 500 | 12 | Front/Back distance by hand (mm) | 100 |
| 6 | Main Rolling motor (KW) | 2.2 | 13 | Power supply (may be customized) | 3P 380V 50Hz |
| 7 | Spindle speed (rmp) | 0.05-1 | 14 | Welding type | SAW or Open arc welding |
3. Main advantages:
1. Realizing hardfacing process and heat preservation process synchronously, guaranteeing digital control between the surfacing layer temperatures in the process of hardfacing.
2. Realizing welding of automatic recovery and avoiding the dust pollution, improving the working environment.
3. Wire stability, wire torque in process of surfacing, which can realize high speed surfacing and swinging overlays, increased melting and depth of molten pool apply efficiency.
4. Strengthen the arc of molten pool of electromagnetic and mechanical agitation role in the process of the swinging hardfacing, making the weld microstructure becomes more reasonable and uniform.
5. It can achieve automation control for all the welding process parameters including the current, voltage, wire feeding speed, walk line speed, walk line distance, weld bead width, weld bead pendulum wide, welding time, etc.
Roll surfacing welding machine is a special kind of welding equipment; it is combined by head and tail welding positioner, submerged arc welding power, wheel frame etc. Welding machines’ basic classifications are according to the size of the loading, also with reference to length of the workpiece, and the workpiece parameters.
Product Application:
widely used in each kind of hot roller, beam steel roller, color metals roller, and grind coal roller, etc various works pieces to prepare to protect and repair the work.
Product Advantage:
- Combo unitized hardfacing and machining
- high quality
- Reasonable price
- good service
