| PLAZARIUM TPS plasma system with industrial plasma torches are designed to create a high-temperature plasma jet of large volume and thermal power based on various plasma-forming gases (steam, air, nitrogen, hydrogen, oxygen, argon, etc.). Industrial plasma torches are applicable in any thermal technological application, including testing and checking the resistance of any materials to any temperature range in the flame contact zone (more than 5000 °C). |
Testing procedure: A plate or cube made of refractory material is exposed to a plasma jet and data are obtained about dependence of the temperature change with time, depending on the distance from the nozzle exit and power in the plasma torch arc in PLAZARIUM TPS industrial plasma system.
Heat removal from the product is carried out by natural convection or forced cooling, depending on the task of the experiments. |
Main goals:
1) Changing of the plate temperature with time depending on the power in the plasma torch arc (N) and the distance (L) from the nozzle exit to the plate
2) Dependence of the maximum temperature (within the experiment) in the thermocouple installation point on the distance to the nozzle exit
3) Visible diameters of heat-affected zones with Gaussian normal distribution parameter
4) Determining the heat transfer coefficient during natural or forced convection outside the item
5) Results of estimating the process of heat exchange between the jet and the item
6) Change of temperature in the contact area of the jet and the item wall |
| Plasma units for accelerated testing of refractory materials using a plasma-thermal load have shown the effectiveness of such a tool for accelerated and long-term high-temperature testing up to the destruction of the refractory with the possibility of obtaining information about the thermophysical properties of the refractory and the parameters of permissible operating modes. |
