Title:
METHOD AND APPARATUS FOR HEAT TREATMENT
Document Type and Number:
Japanese Patent JPS62112717
Kind Code:
A
Abstract:

PURPOSE: To perform heat treatment of treating materials having different quality without generating loss of time by discretely conveying materials of different quality to be heat-treated in parallel into a heat treatment furnace by respective conveying elements and varying the conveying speeds from each other.

CONSTITUTION: The materials 21a, 21b, 21c of different quality to be heat-treated are respectively fed from a charging table 12 to the discrete conveying elements 15a, 15c, 15c and are charged through a front chamber 11 into the heat treatment furnace 1. Driving devices 20a, 20b, 20c for the conveying elements 15a, 15b, 15c are respectively independently operated to vary the conveying speeds from each other in such a manner that the respective materials 21a, 21b, 21c can be heat-treated with respective heat curves. The need for making an empty space in the furnace is thereby eliminated and the generation of the loss of time is prevented. The heat treatment of the materials 21a, 21b, 21c of different quality is thus made possible.
