ABSTRACT:
A furnace for preheating and homogenizing aluminum ingots prior to hot rolling same wherein the heating efficiency is improved thus reducing the time required to heat the ingots to the homogenizing temperature. The furnace comprises an elongated housing having a ceiling, a floor and a pair of side walls extending from the floor to the ceiling for defining a chamber which is divided into an upper fan section and a lower ingot heating section. A plurality of fans are disposed in the upper fan section for circulating hot gases to the ingot heating section of the chamber. Baffles are associated with the side walls of the furnace for directing the hot gases toward the lower portion of the ingot heating section so as to cause the hot gases to flow between the ingots to be heated so as to contact the entire side wall surfaces thereof improving heating efficiency.
