Continuous Atmosphere Copper Brazing Furnace 850 Degree For Heaters Radiators

850 Degree Continuous Atmosphere Copper Brazing Furnace for Heaters Radiators

1. Application

The continuous brazing furnace is mainly used for continuous brazing production of various silver, copper,

and aluminum parts. The surface of the product is bright after being treated by the equipment, without

oxidation and decarburization, and the brazing seam is full.The furnace has the advantages of novel design,

reasonable structure, high energy saving and high heat efficiency, stable production quality, safe and

convenient use. It is easy to operate and has no industrial pollution. Advanced temperature control mode,

using intelligent temperature control instrument, intelligent SCR, Schneider Electric switch.The accuracy

of temperature control is ± 2℃. It is advanced, reliable, practical and economical.

2. Main Technical Parameters

3. Composition

The copper brazing furnace consists of drive system, heating system, cooling system, control system, ammonia

decomposition gas supply system and ammonia purification system.Muffle furnace is made of imported high-temperature

resistant stainless steel. The detachable electric heating elements are installed above and below the muffle tank.

The mesh belt is of frequency conversion and stepless speed regulation, and the mixed gas decomposed from

liquid ammonia (75% hydrogen and 25% nitrogen) enters into the furnace to achieve gas protection effect. The

gas direction adjustment device ensures stable atmosphere. After heat treatment in the furnace, the surface of

the product is bright, no oxidation phenomenon, and the product consistency is good.
