摘要： A body of a process furnace for reforming, steam boilers and heating up starting materials is made of steel and comprises an internal lining inside the body and an outer coating outside the body. The outer coating is discrete, structurally heterogeneous and presents a mixture of water (from 60 to 30 vol. %) and polymers with fillers (from 40 to 70 vol. %). Used as the fillers are expanded perlite or microspheres. The thickness of the outer coating is from 0.4 to 2.0 mm. Technical results of the structure is lowering heat loss from the body.

摘要： To improve the stability of spray application of a monolithic refractory in which a water injector is disposed in a material carrier pipe extending from a material supply device to a distal spray nozzle, and application water is injected from the water injector into a spray material that is being carried through the material carrier pipe, a ratio of a flow volume of an application water carrier gas for carrying the application water to be introduced into the water injector to a flow volume of a spray material carrier gas for carrying the spray material is set to 0.07 to 2, and a compressibility index of the spray material is set to 32% or less. Alternatively, a ratio of a flow volume of an application water carrier gas for carrying the application water to be introduced into the water injector to an application water volume is set to 100 to 1,000.

摘要： A system and method for repairing a coke oven having an oven chamber formed from ceramic bricks. A representative system includes a insulated enclosure insertable into the oven chamber and includes removable insulated panels that define an interior area for workers to work in. The insulated enclosure is movable between an expanded configuration and a compact configuration and moving the enclosure to the expanded configuration will decrease the distance between the insulated enclosure and the walls of the oven chamber. Removing the panels exposes the ceramic bricks and allows workers within the interior area to access and the bricks and repair the oven chamber while the oven chamber is still hot. A loading apparatus lifts and inserts the insulated enclosure into the oven chamber. The insulated enclosure can be coupled to additional insulated enclosures to form an elongated interior area.

摘要： A metallurgical system for producing metals and metal alloys includes a fluid cooled mixing cold hearth having a melting cavity configured to hold a raw material for melting into a molten metal, and a mechanical drive configured to mount and move the mixing cold hearth for mixing the raw material. The system also includes a heat source configured to heat the raw material in the melting cavity, and a heat removal system configured to provide adjustable insulation for the molten metal. The mixing cold hearth can be configured as a removal element of an assembly of interchangeable mixing cold hearths, with each mixing cold hearth of the assembly configured for melting a specific category of raw materials. A process includes the steps of providing the mixing cold hearth, feeding the raw material into the melting cavity, heating the raw material, and moving the mixing cold hearth during the heating step.

摘要： 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.
