Method for the preparation of high-strength fine wire of high-carbon steel. |
摘要 |
<p>An improved method for the manufacture of a very fine high-carbon steel wire having a diameter of 50 mu m or smaller by repeating a plurality of cycles each consisting of a patenting treatment and a cold-drawing treatment starting from a base steel wire rod, wherein the final drawing treatment is preceded by a heat treatment of the intermediate wire having a diameter of about 100-500 mu m in an atmosphere of a gaseous mixture of 90-98% by volume of nitrogen and 2-10% by volume of hydrogen at 750-900 DEG C for 1-30 seconds so that the final drawing can be safely conducted without breaking the fine wire. <IMAGE></p> |
