Vertical Vacuum Brazing FurnaceVertical Vacuum Brazing Furnace

Vertical Vacuum Brazing Furnace

Structural Advantage: Features a vertical single-chamber, horizontal bottom-loading structure, which not only facilitates the stable placement and removal of large workpieces but also ensures exceptional temperature field uniformity inside the furnace chamber. Core Performance: Typical operating temperature of 1320°C, with an ultimate vacuum reaching 5.0×10??Pa. Equipped with molybdenum-lanthanum alloy heating elements, it achieves oxidation-free, high-quality brazing. Intelligent Integration: Fully automatic control system with comprehensive fault self-diagnosis and process management functions. Supports inert gas charging adjustment from 0.5Bar to 10Bar absolute pressure, meeting stringent process requirements.

Introduction

Vertical Vacuum Brazing Furnace is a precision welding equipment developed by Yuanhang Industrial Furnace specifically for materials such as superalloys, stainless steel, and titanium alloys. This equipment is widely used for vacuum brazing of aero-engine blades, precision heat exchangers, and gas turbine components. Its vertical structure, combined with the molybdenum-lanthanum alloy heating system, maintains excellent structural stability and temperature control accuracy at high temperatures, ensuring that the welded products are oxidation-free, have minimal deformation, and exhibit excellent strength.
