20th International Forgemasters Meeting - IFM 2017

We reinforced steel plants newly and started the production of the large steel ingot of 100 tons in December, 2016. (The maximum size of the conventional steel ingot was approximately 75 tons.) The larger steel ingots manufactured in the bottom casting, and the larger ingots were forged in the 8000 tons press machine. The method to produce the high quality of steel ingot was studied by using the simulation software CPRO (Casting Professional), and we tested the simulation result with the steel ingot. As the results of the simulation, the distribution of carbon concentration in the 100 tons ingot was similar that in the 70 tons ingot.
