[0002] Due to the characteristics of high melting point, high hardness and good chemical stability of refractory metals, their application fields are constantly expanding. In application fields with high-temperature or corrosive medium working environments, such as thermocouple protective sleeves of high-temperature furnace components, tubular electrodes, flow guide pipes in the glass industry or gas flow guide pipes in high-temperature furnaces, etc., higher requirements for thin walls and small diameters are put forward for the pipes. Therefore, it is very difficult to achieve simply by using the pipe rolling technology, and the drawing process needs to be adopted to prepare small-diameter refractory metal pipes.
