This product uses the oscillating cup method to measure the viscosity of high-temperature melts, providing a non-contact, high-resolution measurement. The sample is sealed within a crucible, effectively preventing oxidation during testing and addressing the issue of strong corrosivity in the sample.
Test Method | Oscillating Cup Method |
Maximum Operating Temperature | 2000℃ |
Operating Atmosphere | Protective Gas |
Vacuum Level | ＜20Pa |
Test Range | 0.1-10cP |
Test Accuracy | ±3% |
Temperature Field for High-Temperature Melt Viscosity Measurement
The tester provides a controlled temperature field for measuring the viscosity of high-temperature melts. The furnace body features a flanged connection at the top and bottom ports. The lower flange secures the furnace opening, welded into a cylindrical structure, and includes water inlet and outlet for cooling. The upper flange secures the cavity of the suspension system, with the flange sealed using an O-ring made from silicone rubber and locked in place with a locking ring.
Suspension System for Measurement
The suspension system includes components such as the inertia disk, mirror cavity, and filament cavity. The inertia disk is connected to the motor via a suspension wire, and is further connected to the sample crucible by a molybdenum rod. The suspension system, from top to bottom, consists of the motor, suspension wire, mirror, inertia disk, molybdenum rod, and crucible. During operation, the motor drives the suspension system to rotate left and right, after which the system relies on inertia to undergo free oscillation.
Electrical Control System
The electrical control system includes a control cabinet, contactors, transformers, silicon-controlled modules, temperature controllers, PLCs, and other components. The system uses major brands such as Chint or equivalent, with the temperature controller being an Eurotherm brand programmable intelligent temperature regulating instrument. The temperature control precision is ±1°C and includes features like PID adjustment, over-temperature alarms, thermocouple disconnection indicators, and temperature compensation.
