What is heavy slag?
Heavy slag, also called metal dross, are heavy burrs that appear during plasma, oxygen and other flame cutting processes. They usually accumulate on the edges of metal and holes. Large pieces of metal slag will cause uneven metal surfaces, so they must be removed.When facing slag from thermal cutting, choose slag hammer machinery from Bonray Grinding.Our Heavy Slag Removal Machines Will Improve Your Production Lines.
Advantage:
Increased safety for employees and machines:
Slag can be sharp and cause injuries during material handling if not removed. In addition, slag can also fall off the parts during other fabrication processes done the line, which in return can cause damage to those machines. For example, a precision leveler or a press brake.
Improved welding results:
Slag along the cutting edges of heavy plate and metal parts impairs the quality of the weld seams. Removing the slag makes the surface cleaner and improves the weld seam quality.
Corrosion protection:
Slag can absorb moisture which can lead to corrosion. Removing the slag protects the surface against environmental influences like rust along the edges.
Aesthetics:
Slag affects the appearance of heavy plate and metal parts. By removing the slag, the surface along the cutting edges becomes smooth, resulting in a more attractive appearance of the metal parts.
Overview
- Slag usually forms on heavy plate and metal parts that are plasma or flame cut (oxyfuel).
- Grinding slag off is not economical.
- Slag is best removed by chipping it off with metal pins (slag hammers).
- The slag hammers make contact with the sides of the slag at high speed and breaks them off the cutting edges.
- Various tool designs for the pins are available. More stiff for tougher adhering slag for example.
