Latest Patents

Koide's latest patents focus on an innovative apparatus and method for aging steel-making slag. The process involves charging normal temperature steel-making slag, which is crushed to a grain diameter of 25 mm or less, into a pressure vessel. This vessel is designed to withstand pressures significantly higher than atmospheric levels. The method includes supplying pressurized steam to heat the vessel and the slag, maintaining a saturated steam condition at pressures of 2 to 10 kg/cm² G for 1 to 5 hours. After the aging process, the pressure is equalized with the atmosphere, allowing for the safe discharge of the slag.
