Title: Method for producing low nitrogen chromium-containing steel
Inventor: MORI SHOWA
IPC: C21C5/28
Filed: 2003-03-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for producing low nitrogen and chromium-containing steel with which the nitrogen concentration can economically be reduced.  <P>SOLUTION: When the chromium-containing steel containing chromium in the preset product chromium concentration range is produced, in a decarburizing process applied in a converter, the chromium concentration before charging into the converter, is made to be in the concentration range of lower by 1.0-5.0 mass% than the product chromium concentration. The nitrogen concentration is reduced in the decarburizing process. During decarburizing or after decarburizing, when the component adjustment is performed by adding the shortage concentration of the chromium, in the case of charging a large quantity of chromium alloy, since the nitrogen concentration is increased by developing the pickup of the nitrogen from the atmosphere, the chromium concentration range for decarburizing is held in the lower range by 5.0 mass% from the concentration range for product.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
