Latest Patents

Rancoule’s patents address refractory compositions for slide gate valves, which control the flow of molten material in industrial processes.

“Refractory Zirconia Mortar” describes an erosion-resistant mortar for bonding a zirconia insert into an alumina-graphite plate. Its composition includes zirconia and alumina, with optional chromium oxide, phosphoric acid, and a binder. Water is added to achieve the plasticity needed for use.

“Zirconia Graphite Slide Gate Plates” covers a corrosion- and erosion-resistant refractory composition intended for slide gate valve plates or inserts. The mixture combines partially stabilized zirconia with silicon metal, alumina, graphite, and a carbonaceous binder. It is pressed into shape and fired in a reducing atmosphere to produce a carbon-bonded component. The patent also describes using high-purity magnesia and yttria-stabilized zirconia to improve hot-strength properties.
