Beschreibungen/Notizen

• By means of metallographic observation, scanning electron microscopy and electron probe micro analysis, the quantity, particle size, distribution, morphology and composition of inclusions in the slab were discussed in detail. Which can provide a reference for the process optimization of IF steel and the production of pure steel slabs. The results show that the content of C, N and O in the IF steel continuous casting slab produced by this plant is controlled at about 20 ppm, and the content of P and S is lower and the steel is relatively pure. Most of the inclusions are below 2 μm. Most of the inclusions are pure Al2O3, a small part contains a small amount of microscopic MnS.
