Plasma melting is a melting technology based on electric industry and gas chemistry. It is a novel high energy density technology developed by human in order to resolve the problem of low energy efficiency of traditional melting technologies. It is widely used for smelting and alloying materials such as refractory metal and non-metallic minerals.Plasma melting has the following advantages.
First, the plasma melting has a higher energy efficiency. The electric energy is easily converted into Thermal energy to melt the materials. Compared to electric arc melting, the plasma melting has greatly improved the energy efficiency. This means that in order to melting the same amount of material, the plasma melting requires much less energy. This helps to reduce the cost of melting, and also prolongs the service life of equipment.
Second, plasma melting has a wide variety of applications. For example, it can be used to smelt and alloy refractory metal and non-metallic minerals. It can also be used to melt the metal matrix composites and even the ceramic materials. The plasma melting is also good at providing the exact composition required in alloy smelting. This way, accurate alloy compositions can be obtained with relatively low energy consumption.
Third, the plasma melting has low pollution level. Since the plasma is generated by a non-polluting, high-temperature plasma process, it does not produce any polluting emissions. This means that the plasma melting does not have the same level of environmental concern as the other smelting processes. This means that there is less chance of causing any pollution-causing emissions from the melting.
Fourth, the plasma melting has good controlability. The precise control of the temperature and atmosphere in the melting process is possible. This helps to ensure precise alloy composition and precise melting temperature can be achieved. Moreover, plasma melting also has good repeatability. This means that the same melting conditions can be obtained in multiple melting processes. This helps to ensure that good quality and uniform materials can be produced with each melting process.
Fifth, plasma melting has a higher safety level. Unlike other smelting processes, the melting process of plasma is controlled by advanced computer system. This helps to reduce the risk of fire and explosion during use. Moreover, since the plasma generates high temperature and pressure, the materials can be melted very quickly. This means that any potential hazard can be eliminated very quickly.
In conclusion, plasma melting has numerous advantages compared to traditional smelting processes. It has higher energy efficiency, a wide variety of applications, low pollution level, good controlability and a higher safety level. Therefore, it is a safe and reliable process for smelting and alloying refractory metal and non-metallic materials.
