Latest Patents
Sonobe's latest patents include a method for improving the characteristics of fused slag material. This innovative method enhances the resistance of fused slag against pulverization during the cooling process and prevents the generation of yellowish turbid water when slag lumps come into contact with rainwater. The method involves forming a slag treatment material by rough crushing a substantially dehydrated heat-treated material containing boron and adding this material to molten slag. Another significant patent is related to modified steel slag and the method of manufacturing it. This patent describes a steel or iron slag, which is a by-product of metallurgy, characterized by containing at least 0.15 wt % of boron in the form of B₂O₃. This slag exhibits resistance against degradation during the cooling-down process and against the generation of yellowish turbid water upon contact with rainwater.
