AI Technical Summary

Problems solved by technology

[0004] In the process of producing nano-nickel powder by plasma arc evaporation method, it is particularly important to grasp the temperature of the crucible. The prior art smelting and evaporating device has an observation tube, and multi-layer high-temperature-resistant transparent glass is arranged in the observation tube. Operators observe with human eyes. Observe the situation inside the crucible in the melting and evaporating device through the multi-layer high-temperature-resistant transparent glass on the top of the cylinder, and feed the material according to the observed melting state of the raw materials in the crucible and the distance between the mouth of the crucible and the solution surface; and the melting and evaporating device needs to be stopped when feeding , the production efficiency is very low; and because the temperature of smelting evaporation is very high, the sensor for measuring the smelting evaporation temperature is often easily broken and the measurement is inaccurate, resulting in inaccurate control of the temperature of the smelting evaporation device, so that the produced nano-nickel powder particles are uneven , causing the problem of poor quality of nano-nickel powder; for this reason, it is very meaningful to develop efficient and stable production methods and equipment for nano-nickel powder
