A process and apparatus for drying or heating a particulate material by means of heat transfer media which is brought into direct contact with the particulate material within a continuously rotating cylindrical drum. The particulate material flows in one general overall direction through the drum and the heat transfer media flows in a generally opposite direction through the drum. The particulate material is subjected to heat treatment by repeatedly coming into direct and immediate physical contact with the heat transfer media in the course of flowing through the drum while it is subsequently separated from the heat transfer media per revolution of the drum.

A method for heating a riser of a molten refractory material in which after a heat molten refractory material is poured into a mold, a melt of the molten refractory material at an upper portion of the mold is directly subjected to induction heating by conducting an electric current by application of an AC voltage at a frequency of from 50 to 1,000 KHz to an induction coil with at least 2 windings around the riser portion containing said melt without induction heating the upper portion of the mold.
