When the laser cutting machine for cutting sheet metal slag blown out

Laser cutting machine for cutting sheet metal slag blow out reason 1. Plate thickness more than cutting big limit. Due to laser cutting machine processing temperature of the molten slag produced is very high, usually in more than 1700 degrees, and slag boiling, convection will many oxygen into the bottom of reaction area, makes the lower metal has been added to the combustion reaction. However, the farther the lower metal contact with oxygen, the less chance for combustion reaction does not occur at the bottom of the base metal, mainly by the heat generated by the combustion reaction to melt, but also reach the state of the melt completely, so the high air pressure, also blow out with slag.
　　2. Auxiliary air pressure too low. Because of slag adhesion is strong, if when the auxiliary gas pressure can not meet the standard, adhesion slag is difficult to blow off.
