Ce2O3微粒对低碳钢夹杂和晶粒度的影响
Effect of Ce2O3 Particle on Crystal Grain Size and Inclusion of Low Carbon Steel
摘要
Abstract
The effect of Ce2O3 particle on inclusion and crystal grain size of steel product was studied by adding Ce2O3 particle into steel. The result shows the content of inclusion in steel will not increase when the particle size of Ce2O3 is lower than 1.13 |xm, but the content of inclusion will obviously increase when the size is higher than 2.34 μm. The Ce2O3 particle can combine with sulfide inclusion and deoxided product, which has the same function as adding rare earth alloy into steel partially. The Ce2O3 particle can reduce the size of crystal grain of cast structure. The average size of crystal grain is reduced from 180 μm to 90~75 μm. And it can also reduce the size of crystal grain of rolled structure. The degree is reduced from level 6.5 to level 11. The best economic and technical norms can be got when the size of Ce2O3 particle is 1.13 μm and the adding content is 0.5% of the content of metal.关键词
