Introduction
The BR-RYL-10 Vacuum Hot Press Furnace is a high-precision system specifically engineered for universities and scientific research institutions. It is designed for the hot press sintering of advanced materials—including inorganic materials, cemented carbides, functional ceramics, and powder metallurgy—under controlled high-temperature and vacuum conditions.
The equipment is ideal for performing sintering performance tests on small samples. By combining thermal energy with mechanical pressure, it significantly enhances material density. Furthermore, the system offers the flexibility to operate under vacuum or controlled atmosphere (inert gas) protection to meet diverse experimental requirements.
Structural Composition
The system features a robust, integrated design optimized for laboratory environments:
Vacuum Chamber: A double-walled, water-cooled stainless steel vessel that ensures high vacuum integrity and keeps the outer shell safe to touch.
Heating System: Configurable heating elements (Resistance or Graphite) tailored to specific process temperatures.
Precision Pressing Unit: A top-mounted hydraulic system coupled with high-stability pillars for uniform pressure application.
Intelligent Control Cabinet: A standalone unit housing the PLC, HMI touch screen, and high-current power supply components.
Dual-Pyrometry System: Features an automated retractable thermocouple and an infrared sensor for seamless temperature monitoring across all ranges.
Key Features
Customization of Heating Elements
The heating configuration is selected based on the target temperature and vacuum requirements. Resistance modules provide stable performance for applications below 1200℃, while high-purity graphite heaters are utilized for processes exceeding 1200℃.
Optimized for Research Efficiency
The pressing range is finely adjustable below 5 tons, making it specifically suitable for small sample sintering. This prevents the resource waste often associated with oversized industrial equipment while maintaining industrial-grade precision.
High-Precision Displacement MonitoringEquipped with a high-accuracy grating ruler, the system monitors sample deformation and shrinkage in real-time with a resolution of 0.02mm. This is critical for studying the densification kinetics of new materials.
Advanced PLC + Touch Screen Control
The system utilizes a closed-loop control architecture integrating the PLC, voltage regulator, and high-current transformer.
Automation: All mechanical and thermal actions are synchronized by the PLC.
Monitoring: The HMI displays vacuum levels, temperature, and displacement data in real-time.
Data Integrity: All process parameters are recorded, can be viewed as trend curves, and are available for download for post-experimental analysis.
Innovative Dual-Sensor Temperature Management
To ensure accuracy and longevity, the furnace employs a hybrid sensing strategy. A W-Re (Tungsten-Rhenium) thermocouple handles the low-temperature phase and automatically retracts as the furnace reaches high temperatures to prevent sensor degradation. An infrared pyrometer then takes over for non-contact, high-precision measurement at elevated temperatures.
