Abstract
PURPOSE: To rationalize the operation and process of brazing and gas soft-nitriding and enhance the job efficiency and productivity, by brazing ferriferous member in furnace, and then adding NH3 gas into the brazing atmosphere gas in the temperature lowering process to perform gas soft-nitriding treatment continuously.
CONSTITUTION: The ferriferous work W having the brazing filler metal set in the junction part is charged from a charge port 3 into a treating furnace 1 of which furnace body 2 is formed with heat resistant members. Next, the work W is carried inward on a conveyor 5, and is heated and brazed in a heating zone 6 held in the brazing atmosphere, and is then sent into a slow cooling zone 7 on the conveyor 5. After being cooled to a specified temperture in this zone 7, the work W is carried into a constant-temperture zone 8, where gas soft-nitriding is carried out by adding NH3 gas. After this gas soft-nitriding process, the work W is taken out from a take- out port 4 provided in the uppermost part of the furnace body 2.
