The continuous controlled atmosphere aluminum brazing furnace is an industrial heat treatment equipment designed specifically for aluminum workpieces. It utilizes a nitrogen protective atmosphere to achieve non-oxidative melt penetration of the brazing material, forming high-strength joints. It is suitable for large-scale continuous production.

Furnace Introduction

1. The continuous controlled atmosphere aluminum brazing furnace utilizes high-performance refractory materials, ensuring superior thermal insulation and minimal no-load losses. The furnace’s protective atmosphere gas distribution system and airtight protective curtain are meticulously designed and manufactured, minimizing high-purity nitrogen consumption. This reduces energy and gas consumption throughout the entire system, lowering production and operating costs.

2. Carefully planned heating furnace zoning, along with the hardware selection and software parameter adjustment of advanced, high-precision temperature control instruments, ensures extremely high furnace temperature control accuracy (±0.2°C) and a product temperature differential of ≤±3°C within the brazing zone (575°C-610°C).

3 . The continuous controlled atmosphere aluminum brazing furnace utilizes an advanced variable-frequency conveyor control system, enabling infinitely variable workpiece speeds and controlling the workpiece’s travel time in each heating zone, ensuring optimal brazing heating curves.

4 . A high-precision oxygen analyzer provides advanced real-time, accurate measurement of the furnace atmosphere.

5 . The spray system features a simple design and is easy to use. The nozzle ensures sufficient and even flux spraying of the brazing workpieces; the air blower ensures that any excess flux is removed from the workpieces.

6 . The drying furnace boasts a high heating capacity and high internal air velocity, ensuring that the workpieces entering the brazing furnace are free of moisture that could harm brazing quality.

7 . The brazing furnace’s water-cooling zone ensures controllable cooling temperatures during the aluminum brazing process, meeting the process curve requirements and ensuring a fine and dense metallographic structure of the brazed welds.

8 . The air blower in the cooling chamber boasts strong cooling capacity, minimal vibration, and low noise, ensuring a clean and comfortable working environment for operators.

9 . An advanced and comprehensive control system integrates and intelligentizes the production line, providing control, warning, and protection systems to ensure safe and reliable operation.
