ス浸炭焼入炉。[Scope of claim for utility model registration] In the process of sequentially transporting carburized and quenched parts,
A separate quenching type continuous gas carburizing and quenching furnace, which has a continuous gas carburizing furnace section that performs preheating, carburizing, and diffusion processes, and a quenching chamber as a separate chamber, and the quenching chamber is divided into a quenching zone and a soaking zone by a partition door. The furnace is divided into a quenching zone, and the set temperature in the furnace is set slightly lower than the quenching temperature range to rapidly cool the carburized and quenched parts. a quenching zone in which a cold non-oxidizing gas fed from an installed inlet pipe is blown onto the carburized and quenched member by a stirring fan disposed in the quenching zone to quench the carburized and quenched member; The quenching zone includes a soaking and quenching zone in which the carburized and quenched member that has been quenched in the quenching zone is soaked to a proper quenching temperature range and then charged into a quenching tank filled with a quenching medium. Features a separate chamber quenching type continuous gas carburizing and quenching furnace.
