ABSTRACT:
Apparatus for heating and pouring metal and metal alloys. A metal melting and pouring apparatus suitable for graining the molten material is described. A graphite crucible having at least one exit orifice in its lower, tapered portion, a graphite barrier plate or disk having a plurality of orifices located within the crucible on the tapered portion thereof, and an element for heating the apparatus to temperatures sufficient to melt the metal, have been found to produce a steady stream of consistent droplet-size molten metal, while maintaining a choosen level of liquid metal in the crucible to prevent less dense impurity materials from passing through the exit orifice(s) of the crucible, and to improve the efficiency of melting additional metal subsequently introduced into the crucible.
