More Information
Summary:The disclosure provides an apparatus for controlling the rate of heat transfer from as-cast railroad wheels after their removal from the mold utilizing a plurality of vertically adjustable caps with a cap positioned over each whee l to control the rate of heat transfer therefrom as it is transported to a successive operation, each cap having a generally symmetrical shape to inhibit or reduce deflection of radiant energy from the wheel, and the disclosure also provides a method for controlling th e rate of heat transfer including a control system to provide the requisite displacement of each cap from the associated wheel to control cooling of the wheel prior to its subsequent operation.
