Manner of the aluminum wax attaching which uses the non corrosiveness flux and uses the non corrosiveness flux the aluminum wax attaching reactor

摘要

PURPOSE: To reduce variance of the brazing temperature, to reduce influence of a poisonous gas component and to improve productivity by intercepting direct radiation in protective atmosphere gas and heating works by forced convection. ;CONSTITUTION: The aluminum brazing furnace l which is connected with conveyors 51-56 and can fill up the protective atmosphere gas therein is composed of a preheating chamber 13, a brazing chamber 14 and a slow cooling chamber 15. In the brazing chamber 14, the works are heated by almost forced convection instead of radiant heat by convection of a fan 8 executed by driving heat of a heater 7 by a motor 81 and fitting of a radiant heat intercepting member 9 of a baffle 16. Consequently, the variance of the temperature between respective brazing parts of the works and between the works is reduced and defective brazing is reduced.;COPYRIGHT: (C)1993,JPO&Japio
