Document Type and Number:
WIPO Patent Application WO/2021/117442
Kind Code:
A1
Abstract:
The present disclosure pertains to a mesh-belt-type continuous sintering furnace with which it is possible to manufacture a sintered body having exceptional surface properties and in which a mesh belt has a long service life. The mesh-belt-type continuous sintering furnace according to the present disclosure comprises a furnace body part (2), and a mesh belt (3) that travels inside the furnace body part (2) and transports a material (10) to be heated, wherein: the mesh belt (3) is configured in a reticulate shape from a plurality of stainless steel wires (31); the furnace body part (2) has a preheating part (21) that preheats the material (10) to be heated, a sintering part (22) that sinters the preheated material (10) to be heated, and piping (25) that jets an inert gas; the preheating part (21) has at least one heating device (211) that performs combustion at a mixing ratio in which the proportion of hydrocarbon gas is higher than in a theoretical air-fuel ratio; the sintering part (22) has a heating device (221) by which the atmosphere inside the sintering part (22) can be controlled; and the piping (25) has jetting openings that are opened toward the mesh belt (3) from within a range from beside the mesh belt (3) to below the mesh belt (3), the jetting openings being provided from the furthest-downstream heating device (211) of the preheating part (21) to the upstream side of the sintering part (22).
