Refractory metals are nickel-based alloys, titanium alloys, tool steel, special stainless steel and other varieties,its deformation resistance is two to three times that of steel, with good fatigue resistance, corrosion resistance and high-temperature performance, are widely used in aerospace, defense, nuclear power, medical and other fields, is the key material necessary for major equipment and high-end manufacturing.
The refractory metals are mainly produced in the mode of multi-fire forging and cross-row rolling; the production batches are small and the quality fluctuates greatly between batches; for the problems of low thermal conductivity and narrow thermal processing range of refractory metals, the near constant temperature rolling process is used to compress the rolling interval and control the temperature field of the deformation process to improve the consistency of the products and ensure the continuous production.
