Claims

[Scope of utility model registration request]

In a sealing device on the outlet side of a belt furnace for unreduced metal powder in which metal powder is reduced and decarburized on a steel belt in a reducing atmosphere, the cake is communicated with the reducing atmosphere to crush the fixed cake that has been reduced and decarburized. a first sealing chamber having an automatic opening/closing damper for discharging the crushed cake and a seal roll of the steel belt; and one or more chambers provided at the lower part of the first sealing chamber and having an automatic opening/closing damper for discharging the crushed cake. An inert gas supply that supplies inert gas to the sealing chamber, which is comprised of a subsequent sealing chamber, a belt sealing chamber connected to the sealing roll, a pressure detector, a differential pressure transmitter, an inert gas piping, an automatic supply valve, etc. a discharge device comprising an exhaust gas pipe, a three-way switching valve, an exhaust valve, and an oxy-heloxide concentration meter for discharging the inert gas in the subsequent seal chamber into the belt seal chamber or into the atmosphere; 1. An outlet side sealing device for a belt furnace for unreduced metal powder, comprising: an ink-pal timer that controls the automatic opening/closing damper and valve according to the speed of the belt.
