HEAT TREATING APPARATUS AND METHOD FOR MANUFACTURING MATERIAL TO BE HEAT TREATED

摘要

PROBLEM TO BE SOLVED: To solve the problem that in a multi-chamber type heat treating furnace, a partition wall is heated mainly by a heat by means of its radiation, the heat is transferred in the partition wall by means of a heat conduction or the heat is transferred on the surface by means of its radiation and its adjacent chamber is heated from the partition wall by means of the radiation. SOLUTION: A heat treating apparatus comprises a heat insulation partition wall 2 in the heat treating furnace of a vertical plate structure in which plate- like heat insulators 17 are aligned at a predetermined interval. Thus, since a thermal conductivity in conveying direction is reduced, a heat transfer due to the conduction can be decreased.
