Abstract: A foamed lightweight monolithic refractory castable is provided. The castable includes one or more refractory aggregates as a main constituent, one or more foaming additives in a range of 0.1 wt% to 3.0 wt%, one or more cellulosic powder air-entraining additives in a range of 0.005 wt% to 2.0 wt%, one or more binders in a range of 1 wt% to 40 wt%, and one or more superplasticizers in a range of 0.05 wt% to 0.5 wt%. The refractory aggregates include at least one of alumina and silica. The foaming additives include at least one of alkylbenzene sulfonates, alkene sulfonates, and hydroxylalkane sulfates. The superplasticizers include at least one of sodium polyacrylates, naphthalene sulfonates, polyethylene glycols, polycarboxylates, polyacrylates, and polycarboxylate ethers.

Abstract: Mounting hardware for mounting an insulation module on a furnace wall. The hardware comprises a mounting bracket embedded within the module. The bracket has a plurality of flexible tabs, each tab having a fixed end and a free end. The free ends of the tabs are arranged about a central point and are movable (flexible) relative to the fixed ends. A mounting stud is provided having a fixed end attachable to an inner surface of a furnace wall and a free end. The stud extends from the inner surface, and the stud has an annular groove adjacent the fixed end. The stud is dimensioned to extend through the mounting bracket between the free ends of the tabs and to cause the tabs to flex as the bracket moves along the stud from the free end towards the fixed end, wherein the tabs snap and lock into the annular groove when the bracket reaches the annular groove.

Abstract: A measurement system is provided for predicting a future status of a refractory lining that is lined over an inner surface of an outer wall of a manufacturing vessel and exposed to an operational cycle during which the refractory lining is exposed to a high-temperature environment for producing a non-metal and the produced non-metal. The system includes one or more laser scanners and a processor. The laser scanners are configured to conduct one or more pre-operational laser scans of the refractory lining prior to the operational cycle to collect data related to pre-operational cycle structural conditions, and one or more post-operational laser scans of the refractory lining after the operational cycle to collect data related to post-operational cycle structural conditions of the refractory lining. The processor is configured to predict future status of the refractory lining after subsequent operational cycles based on the determined exposure impact of the operational cycle.

Abstract: A measurement system is provided for predicting a future status of a refractory lining that is lined over an inner surface of an outer wall of a metallurgical vessel and exposed to a heat during which the refractory lining is exposed to molten metal. The system includes one or more laser scanners and a processor. The laser scanners are configured to conduct a plurality of laser scans of the refractory lining when the metallurgical vessel is empty. At least one of the laser scanners is configured to laser scan the refractory lining prior to the heat to collect data related to pre-heat structural conditions of the refractory lining. At least one of the laser scanners is configured to laser scan the refractory lining after the heat to collect data related to post-heat structural conditions of the refractory lining. The processor is configured to predict the future status of the lining.
