Nitrogen Steels

The experiments of high nitrogen steels refining have been researched with high pressure and bottom-blown nitrogen in laboratory. We can gain high nitrogen nickel-free stainless steels that its content is more than 0.9%. The research indicates that the temperature influences nitrogen content greatly in the processes of smelting and concreting. The results are shown that saturated nitrogen content in steel increased slightly. When the temperature is as high as 1913K, the nitrogen content can reach 1.191%.

Zone Segregation

Segregation and liberation occur easily in high nitrogen stainless steels, which can result in the formation of pores and the discarding of the steels. So it is very important to investigate the segregation and liberation theory during the solidification process of high nitrogen stainless steels. In the manuscript, the pouring and solidification progress of high nitrogen steels ingots were simulated through Pro Engineer and PROCAST software. The dynamic variation of temperature field and pressure field were obtained. With the results of PROCAST, the macrosegregation of 20kg weight ingot and 1.7 tons weight ingot were predicted using mathematical model of zone segregation. The predicted results show that 20kg weight ingot has no obvious macrosegregation and 1.7 tons weight ingot has obvious macrosegregation, which is consistent with measuring results. It shows that the accuracy of simulation and calculation to segregation of high nitrogen steels solidification process based on PROCAST software is high.
