Someof themost important decisions that the heat treater willmake are related to the selection of
furnaces and ancillary equipment. These decisions involve selection of the energy source, gas or
electricity, which is vital to the overall profitability of the heat treatment process. Another is the
selection of the furnace transfer mode, batch or continuous, and the particular furnace type. If a
furnace is rebuilt, the proper choice and installation of the refractory material are vital.
