ABSTRACT:
The invention relates to a high frequency heat-treatment of long continuous metal blanks wherein the long continuous metal blanks are fed in their lengthwise direction by a pushing rod which is insensible to the high frequency to pass through a high frequency heating furnace and to be introduced into a cooling chamber in which a transferring means consisting of a plurality of, for example, chain conveyors is provided to transfer the long continuous metal blanks laterally, i.e. in the direction perpendicular to their lengthwise direction for sufficiently cooling them. According to the invention the apparatus can be installed in a relatively small space and the long continuous metal blanks can be successively subjected to the heat-treatment efficiently.
