SINTERING FURNACE
Document Type and Number:
WIPO Patent Application WO/2021/130845
Kind Code:
A1
Abstract:
The present invention includes: a furnace chamber (12) that is formed so as to penetrate from the inlet (12a) to the outlet (12b) of a sintering furnace (10); a roller (13) that conveys an object to be sintered from the inlet (12a) to the outlet (12b) through the furnace chamber (12); and a plurality of radiant tube burners (15) that are arranged in the furnace chamber (12) so as to heat the conveyed object to be sintered. The radiant tube burners (15) are arranged in parallel in such a manner that adjacent radiant tubes (15) extend from the base to the leading end in opposite directions. The furnace chamber (12) is formed by a furnace wall (11) surrounding the roller (13), and the radiant tube burners (13) may be arranged along the floor (12c) and ceiling (12d) of the furnace chamber (12) so that the longitudinal direction from the bases to the leading ends of the radiant tube burners (13) is substantially orthogonal to the direction in which the object to be sintered is conveyed.
