A vacuum-purging, semi-continuous controlled-atmosphere brazing (CAB) furnace was delivered to a North American automotive aftermarket manufacturer. Seco/Warwick, which supplied the unit, says it is the first of its kind.

Diffusion bonding has been utilized to join high strength and refractory metals — those that are either difficult or impossible to weld by other means — for many years.

A North American manufacturer of punches and dies ordered a dual-chamber, fiber-lined furnace to process small parts in wire baskets and parts wrapped in foil during hardening. The upper chamber heats to 2200°F (1205°C), and the lower draw chamber heats to 1600°F (870°C) with 23 kW of power.

Box-type chamber furnaces are suited for use in nearly all types of thermal processing and heat treating applications.

While the approach of limiting hazardous emissions is for the benefit of the environment and society, the method used to define the limitation can significantly alter its outcome (e.g., if it does not account for the full extent of influencing factors). 

A report from NFPA looks at recent oven, furnace and dryer explosions — in particular, explosions in curing ovens, electric arc furnaces and grain dryers.
