  • DRY REFRACTORY COMPOSITIONS WITH REDUCED LEVELS OF RESPIRABLE CRYSTALLINE SILICA
    Publication number: 20210331982
    Abstract: A silica-based dry refractory composition (“DRC”) comprising, by weight, about 95% to about 99.9% silica, and about 0.1 to about 5% binder, wherein the silica comprises about 40% to about 80% quartz and about 20% to about 60% fused silica, and the DRC has less than about 5% crystalline silica having a size less than 10 ?m. A method of forming a refractory lining is also provided.

  • Refractory binder system
    Patent number: 10464848
    Abstract: A refractory formulation containing an anhydrous solvent, an oleophilic rheology modifier and a refractory aggregate exhibits non-thermoplastic behavior, and remains plastic and formable at temperatures in the range of 10 degrees Celsius to 180 degrees Celsius. The oleophilic rheology modifier may effectively bind with the solvent to create a gel-like structure with organic solvents with moderate to high polarity. A phyllosilicate clay that has been treated with a quaternary fatty acid amine may be used as the oleophilic rheology modifier.
    Type: Grant

  • Refractory lining repair material
    Patent number: 10295261
    Abstract: A formulation containing polymer, resin and cement combined with aggregate can be used as a gunnable mix that is applied to a surface by being conveyed pneumatically in dry form to a nozzle, where water is added. Polymer in the gunnable mix enables it to adhere and bond to a surface, such as carbon brick, of a lining of a vessel used for the containment of molten metals. The formulation may be used, for example, to repair and protect blast furnace hearth linings.
