◆ Technical features:

The high-temperature furnace of the RTW-2010 metallurgical melt physical property testing device is a water-cooled stainless steel shell molybdenum disilicide resistance furnace.

The long-term operating temperature of the heating furnace is 1600 ℃, with a maximum heating temperature of 1700 ℃.

The molybdenum probe and measuring rod are coated with an anti-oxidation layer, and the inner and outer graphite crucibles are reusable, greatly reducing the cost of a single test;

The lifting mechanism is driven by servo motors, with large-diameter guide columns, graphite guide sleeves, and screw drive, ensuring smooth lifting and lowering of the heating furnace. Stepless speed regulation, high control accuracy, and accurate positioning.

Adopting electric horizontal rotation support, the device for testing melt viscosity automatically switches between testing melt density, surface tension, and conductivity, ensuring smooth and reliable operation.

The rotational speed (1-32) of the melt viscosity probe can be set, and there are multiple types of probes with large range and high accuracy.

Adopting high-precision electronic balance with an accuracy of 0.001g.

Using branded computers and Siemens PLC automatic control, the system runs stably with a low failure rate.

The viscosity of the melt can be measured continuously with temperature control and cooling, or at a fixed point with constant temperature.

The viscosity, surface tension, conductivity, and density of high-temperature melt are all measured under computer and PLC control, automatically searching for the liquid level, controlling the insertion depth of the probe, automatically delaying, and completing the testing work automatically.

The experimental data is automatically collected and processed by the computer, and the experimental data and curves are output by the printer.

◆ Equipment Usage:

Metallurgical melts include metal melts and slag. In the smelting and casting process of pyrometallurgy, many physical and chemical reactions are closely related to the physical and chemical properties of the metal melt and slag. It is also related to the viscosity, surface tension, and diffusion of various elements in the molten steel. Therefore, studying their physical and chemical properties is crucial for metallurgical processes. The RTW-2010 metallurgical melt physical property testing device can test the viscosity, surface tension (optional), density (optional), and conductivity (optional) of metallurgical melts.
