The equipment adopts a large vertical vacuum chamber structure, a bottom-opening lifting loading system, and is equipped with a high-purity graphite heater, multi-layer graphite heat shield, high-vacuum pumping system, and PLC intelligent control system. It can complete various high-temperature heat treatment processes in high vacuum or low-pressure protective atmosphere environments, effectively reducing material oxidation and improving product microstructure uniformity, mechanical properties, and surface finish. The furnace body is designed and manufactured for 1800℃ and can operate stably for extended periods in a 1600℃ vacuum environment, supporting protective atmosphere processes such as nitrogen.
Product Features
- High Vacuum Degree and Excellent Sealing Performance
Ultimate vacuum degree 2×10⁻⁵Pa; the vacuum acquisition system takes less than 40 minutes to decrease from atmospheric pressure to 5×10⁻³Pa (empty furnace). After 24 hours from ultimate vacuum shutdown, the remaining vacuum degree is better than 1Pa, with a pressure rise rate ≤0.5Pa/h. Meets the stringent requirements for annealing high-purity materials.
- High-Temperature Graphite Heater + High-Purity Graphite Felt Thermal Shielding
Utilizing a high-temperature graphite heater and high-purity graphite felt thermal shielding, it can operate under vacuum and protective atmosphere. The insulating ceramic parts are made of high-temperature resistant boron nitride, ensuring insulation and heat resistance. The workpiece stage consists of a high-temperature graphite support and a high-temperature graphite disc, ensuring support strength requirements and a long service life under high temperatures.
- Bottom-Lever Lifting Opening for Convenient Loading and Unloading
The vacuum chamber has an inner diameter ≥Ф1200mm×1800mm and adopts a bottom-lifting opening opening structure for loading. High-quality carbon steel with painted finish, helium mass spectrometry and quadrupole mass spectrometry leak detection, spiral water-cooled jacket, and fluororubber ring seal. An observation window is provided in the vacuum chamber for easy monitoring of the internal condition.
- Dual IGBT Power Supply + Imported Temperature Controller for Precise Temperature Control
The heating and temperature control system is equipped with two IGBT power supplies, each with a power ≥25KW, voltage 50V, and current 500A. Imported temperature controllers are used, enabling multi-segment programmable temperature control with an accuracy of ±1℃. It can be controlled according to a set program to meet the requirements of complex annealing process curves.
- Two Working Gas Paths with Digital Gas Flow Display
The system consists of a charging valve, pipelines, needle valves, mass flow meters, connectors, etc., with two paths (for nitrogen charging after vacuum release and for protective atmosphere charging). The gas flow is digitally displayed. It can be supplied with protective atmospheres such as nitrogen and argon to meet the requirements of different annealing processes.
- Digital vacuum gauge, measuring range 1.0×10⁵Pa～1.0×10⁻⁵Pa
Equipped with a digital vacuum gauge, it has a wide measuring range and displays the vacuum level inside the furnace in real time, making it convenient for operators to monitor and record the process status.
