    • A method of preserving cooked food. Food is cooked in a cooking appliance to provide pre-cooked food and placed in a holding compartment of a food warming apparatus for a duration of holding time. The pre-cooked food is heated in the holding compartment for at least a portion of the duration of holding time by delivering in a pre-programmed manner an amount of radiant heat to the pre-cooked food from a radiant heat source positioned above the pre-cooked food. The amount of radiant heat delivered to the pre-cooked food is varied to maintain the food at a selected holding temperature by delivering radiant heat to the pre-cooked food at a first level during a first phase of the duration of holding time and delivering radiant heat to the pre-cooked food at a second level during a second phase of the duration of holding time.

    • A lining element for heat treatment furnaces comprises lining material consisting of insulating material, an elongate supporting element for transversely piercing the lining material, and elongate fastening members for attachment of the element to the interior furnace wall provided at both ends of the supporting element. The free ends of the fastening members are provided with projections extending transversely to the longitudinal direction of the fastening members at the height of a planar interior surface of the element, which surface will be closest to the interior furnace wall.

    • A spray cooling system for cooling a furnace for the melting or treatment of molten metal, and particularly the roof and/or sidewall of electric-arc, plasma-arc and ladle furnaces. Other types of metal treating furnaces and accessory equipment may also be cooled with the system of the invention. In the invention, spray headers and pipes (14, 16, 18) supply coolant to spray nozzles (70) distributed within a coolant space in a roof structure (10) to spray coolant against the working plates (22) of the roof. The spray pipes and headers also comprise part of the framework for the roof, resulting in a simple, lightweight, one-piece structure. A pump (56) is connected to evacuate the coolant from the coolant space, and thermocouples (58) are embedded in the working plates to monitor their temperature and operate controls to adjust the flow rate so that only the amount of coolant necessary to maintain a desired temperature is supplied to the roof. The sprays of coolant produce many small droplets which provide a large surface area for more effective cooling, and at least a substantial portion of the droplets are vaporized during cooling whereby the latent heat of vaporization of the coolant is utilized to provide a significantly increased cooling rate. Similar arrangements may be used to cool the delta and/or sidewall of the furnace.The method of cooling a furnace by directing sprays of coolant against the working plates is also disclosed.
