Title
(EN) SINTERING FURNACE
(FR) FOUR À FRITTER
Abstract
(EN)
In an example implementation, a sintering system includes a detection gas line to enable gas to flow into a sintering furnace from an external gas supply. The system includes a detection gas port inside the furnace through which gas from the detection gas line is to flow into the furnace, and a registration feature inside the furnace to enable positioning of a token green object proximate the gas detection port. The system includes a gas flow monitor to detect changes in gas flow through the detection gas line when the token green object shrinks during a sintering process in the furnace.
(FR)
Selon un mode de réalisation cité à titre d'exemple, cette invention concerne un système de frittage, comprenant une ligne de gaz de détection conçue pour permettre à un gaz de s'écouler dans un four à fritter à partir d'une alimentation en gaz externe. Le système comprend un orifice de gaz de détection à l'intérieur du four à travers lequel le gaz provenant de la ligne de gaz de détection doit s'écouler dans le four, et un élément de repérage à l'intérieur du four pour permettre le positionnement d'un objet cru de marquage à proximité de l'orifice de détection de gaz. Le système comprend un dispositif de surveillance d'écoulement de gaz pour détecter des changements d'écoulement de gaz à travers la ligne de gaz de détection lorsque l'objet cru de marquage se rétrécit pendant un processus de frittage dans le four.
