Title:
COMBINED CONDUCTION/CONVECTION FURNACE
Document Type and Number:
Japanese Patent JP2008151500
Kind Code:
A
Abstract:

To provide a single furnace system combining and integrating a plurality of distinct heating environments.

The single furnace system 10 integrates a combination of two or more distinct heating environments (including a conduction heating environment 23 and a convection heating environment 24 in a preferred embodiment). As a result, the plurality of environments specify a continuous heating chamber 14 through which a moving workpiece 50 (such as a casting) is shifted from one heating environment to the other heating environment without being exposed to the atmosphere. In accordance with a preferred method, the transition of the casting from the one environment to the other environment is achieved with no meaningful change in temperature.
