    摘要: 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 wheel 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 the 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.

    摘要: A wheel has both wear resistance and heat-crack resistance sufficient for use in a high-speed railway vehicle. The chemical composition of a base steel comprises 0.4 to 0.75 % C, 0.4 to 0.95% Si, 0.6 to 1.2% Mn and less than 0.2% Cr. The wheel has a pearlitic microstructure in a region of at least 50 mm in depth from the tread surface of the wheel. When the tread of the wheel is quenched, a particular cooling process is applied in order to obtain the pearlitic structure.

    摘要: A steel for high-strength solid wheels and tires for railroad traction vehicles and cars that is more tenacious at the strengths typical of existing steels, and that is less likely to fracture even at constant braking. The steel has a specific ratio between major, alloying and companion elements, so that the steel is of high purity and uniformity. The heat treatment ensures a structure of excellent tenacity at high strength and of special endurance.

    摘要: A vehicle wheel formed of a heat treatable aluminum alloy and including an axially center area and opposite axially end areas is subjected to a solution heat treatment and then is cooled in a controlled manner to improve the dynamic strength of the wheel. Specifically, cooling is achieved by cooling the center area faster than the end areas. More particularly, a cooling medium first is sprayed on the center area and then is sprayed on the end areas.
