Application

The viscosity of melt can be measured during a cooling process or at a constant temperature state while the rotation speed of rotor is also adjustable, which ensures the accuracy and reliability of test results. The data during test is automatically recorded and processed by a computer while print of recorded data and curves is also supported. It can be applied for the determination of comprehensive physical property of blast furnace slag, mold flux, steelmaking slag, etc.

Main features

1.The particular viscometer can ensure the reliability and stability of the test process in long-term, which also ensures the consistency and reproducibility of test results;

2.The crucible temperature is directly measured and applied to represent the temperature of sample, which is accurate and reliable;

3.The mechanism of probe with a two-dimensional motion mode and the digital control of vertical movement are conducive to the precise control of probe position in melt sample;

4.The rotational speed of rotor can be precisely adjusted in a wide range;

5.The level of liquid can be automatically determined during the testing of viscosity, surface tension and density;

6.The viscosity of melt can be measured during a cooling process or at a constant temperature state.

7.Silicon molybdenum heating element can provide high testing temperature with long span.

8.A fully automatic control mode from ambient temperature to high temperature.

9.The data during test can be automatically recorded, processed and analyzed.
