Reducing headaches associated with slag on laser .

Slag buildup does occur on copper grating, but it is also removed much more easily than slag that builds up on mild steel slats. When a metal fabricator processes thicker material on the laser cutting machine with copper slats, it can expect to see spatter from the cutting process, but it is far less than it would be if the laser had steel slats.

GENERAL INFORMATION Iron & Steel Slags ... - National Slag

Processed steel slag is strong, hard, durable, dense and roughly cubical particles which make it especially suitable for use in road construction. Not all steel slag is expansive, but water quenching is the first step in weathering of steel slag which may be essential to provide a stable, non-expansive construction material. In the cooling process,
