Furnace

In a furnace comprising a furnace chamber surrounded by fireproof walls formed with a work inlet and a work outlet and having heating means such as a burner provided toward the inside of the furnace chamber, a work mounting turntable rotatably provided within said furnace chamber, and a circulating fan provided coaxially with said turntable, said turntable having a plurality of work mount portions formed at the outer circumferential positions thereof separately at regular angular intervals and a plurality of diffusing blades formed at inner circumferential positions inside said work mount portions coaxially with said turntable so as to face said circulating fan, whereby a gas within said furnace chamber heated by said heating means is uniformly circulated toward said work mount portions from said circulating fan through said diffusing blades;

• the improvement comprising:
• work carry-in means for carrying a work into said furnace chamber through said work inlet while mounting said work on said work carry-in work means so as to to transfer said work onto a selected one of said work mount portions;
• and
• work carry-out means for carrying out a work mounted on a specific one of said work mount portions through said work outlet while mounting said work on said work carry-out means,
• each of said work mount portions being provided with a plurality of strip members with their respective one ends supported at the outer circumferential positions of said turntable, said strip members being separated at regular intervals, each of said work carry-in means and said work carry-out means being arranged to have its forward end constituted by a plurality of strip members separated at regular intervals so that said strip members of any one of said work mount portions can enter the respective intervals of any one of said work carry-in and work carry-out means.
