Abstract: Introduced in the paper are the experiments concerning and application of the Russian type dies for steel tube cold-drawing process conducted by No. 3 I & S Works, Hefei I & S Corp. The said experiments show that with the tube-drawing process featuring a combination of Russian type dies and Chinese type dies, the die consumption can be considerably reduced, and tube-drawing quality improved. Furthermore, the employment of the inner die surface strengthening process with multi-metalization will greatly increase the service life of the inner dies.
