Class Information
Number: 266/239
Name: Metallurgical apparatus > Means for melting or vaporizing metal or treating liquefied metal > With means to discharge molten material > By changing ambient pressure on material surface, e.g., suction
Description: Device wherein the means for discharging material from the treating vessel includes means for varying gas pressure at a selected location on the exterior of the molten mass to create a gas pressure gradient across the exterior which is effective to deliver material from the vessel.
