CARBON DIOXIDE SNOW HANDGUN FOR METALLURGY

摘要

Dry ice lance intended, in particular, for inerting a molten metal. It comprises a supply line for pressurized liquid carbon dioxide intended to be connected to a supply source for pressurized liquid carbon dioxide, a T-shaped part, one end of which is connected to said pipe and both of which other ends are connected respectively to at least one liquid carbon dioxide transport line and to a controlled valve, the outlet openings of the controlled valves being connected together by a V-shaped connecting piece which opens into a pipe d evacuation of snow.
