Applied Research of Smelting High Nitrogen Steels by Bottom-Blowing Nitrogen

Abstract:

The method of smelting High nitrogen steels by blowing nitrogen from the device bottom is a promising way of increasing nitrogen with gas. Introduced the device and technical development of smelting High nitrogen steels in domestic and foreign countries, expounded the method and character of dissolving nitrogen into liquid steel at high temperature and high pressure, and analyzed the advantage of increasing nitrogen by bottom-blowing nitrogen. The domestic research is at the developing period of experimental research. The High nitrogen steels which content is more than 1.0% was produced with bottom-blowing nitrogen method at high pressure. The velocity of dissolving nitrogen with bottom-blowing was increased and the smelting time was shortened. The technical effect was very good.
