ABSTRACT:
A method and apparatus for heat-treating a material at high temperatures wherein the material from which the bottom of a furnace chamber is made forms a eutectic with the material to be heat-treated, and does so at a temperature lower than the heat treatment temperature. A part of the furnace chamber bottom, which part can include the whole or a portion of the furnace chamber bottom, and on which the material to be heat-treated rests is formed at least in part of a material that has the same chemical composition as, or a chemical composition similar to, the chemical composition of the material to be heat-treated. The furnace bottom part on which the material to be heat-treated rests is positioned so that it has no physical contact with the remaining furnace bottom material within the furnace chamber. The furnace bottom part is positioned such that the contact location between the bottom part and the furnace lining material at which the bottom part is arranged, will assume during the heat-treatment process a temperature that is lower than the temperature at which a molten phase will be formed between the materials that are in contact with one another at the contact location.
