Abstract

A continuous heating or pusher-type furnace for the heat treatment of small arts, by which in a closed furnace chamber glide tracks are provided for the intermittent feeding of basket cars in a row between a loading station and a discharge station which is connected gas-tight to the furnace chamber, in the vicinity of which stations there is arranged respectively a reversing device for the translation of the individual baskets from one glide track to the other glide track, whereby the filled baskets automatically can be inserted into the discharge station, and can be emptied by a tipping device with a connecting gravity chute into a quenching bath. The glide tracks with the loading station and the discharging station lie on one plane and at least two glide tracks are provided for the transportation of the filled baskets, the two glide tracks being symmetrically arranged relative to a glide track provided for the return transportation of the emptied baskets.
