PRODUCTION OF CASTING PIG IRON

PRODUCTION OF CASTING PIG IRON

PURPOSE:To prevent the generation of bad shaped appearance of a mold pig iron by using steam having the specific value or lower of droplet diameter, cooling with atomized water spreading and making the specific temp. or lower of super heat at near surface layer of molten pig iron in the mold before...

description PURPOSE:To prevent the generation of bad shaped appearance of a mold pig iron by using steam having the specific value or lower of droplet diameter, cooling with atomized water spreading and making the specific temp. or lower of super heat at near surface layer of molten pig iron in the mold before cooling with much water spraying. CONSTITUTION:In this invention, the super heat at near the surface layer of molten pig iron in the mold before cooling with water spreading is made to be >=50 deg.C. In the case of the general casting pig iron, this can apply the well- known cooling method, but in the case of high Si pig iron having >=2.0% Si, as this solidifying temp. is low, the case, which can not cool to the prescribed temp., is developed. In this case, in this invention, by colliding atomized water particles having very fine, such as
