Abstract

The invention provides a high-temperature viscometer which is characterized in that a crucible support plate is buckled at the top end of a closed flange buckle, the closed flange buckle is connected at the top end of a furnace tube, and the furnace tube extends into a smelting furnace; a vacuum extraction opening is formed in the closed flange buckle; clamping frames are uniformly connected to the bottom end of the crucible support plate at intervals in the circumferential direction of the central shaft, and crucibles are clamped among the multiple clamping frames in a limiting manner; any one of the clamping frames can be turned outwards, and the crucible can be taken and placed through the outward turning of the clamping frame; a lifting module is arranged in the transparent cover, the lifting module is connected with a force sensor, the lower end of the force sensor is connected with a test rod, and the test rod downwards penetrates through the crucible support plate to be connected with a test rotor; in the invention, the test rotor and the crucible are always in a concentric vertical state, and the crucible is high in placement stability, so that the phenomenon that the crucible rotates along with the test rotor to cause a large error of a measurement result is avoided.

Description

technical field

[0001] The invention belongs to the technical field of high temperature viscometers, and particularly relates to a high temperature viscometer. Background technique

[0002] The main application fields of high temperature viscometer include: optical glass, metallic glass, ceramics, metal, slag, mold slag, coal gasification, TFT (thin film transistor) glass substrate and other high temperature melt viscosity measurement. The high temperature viscometer measures the viscosity value by the torque formed by the continuous rotation of the rotor immersed in the test liquid. The torque is proportional to the resistance formed by the viscous drag of the rotor immersed in the sample, so it is also proportional to the viscosity. Using a rotor to measure the viscosity of the melt requires that the instrument should have the characteristics of precise temperature control and accurate viscosity measurement.
