发明名称 Heat-treating methods and systems
摘要 Methods and systems for heat-treating a workpiece are disclosed. A first method involves increasing a temperature of the workpiece over a first time period to an intermediate temperature, and heating a surface of the workpiece to a desired temperature greater than the intermediate temperature, the heating commencing within less time following the first time period than the first time period. A second method involves pre-heating the workpiece from an initial temperature to an intermediate temperature, and heating a surface of the workpiece to a desired temperature greater than the intermediate temperature by an amount less than or equal to about one-fifth of a difference between the intermediate and initial temperatures. A third method involves irradiating a first side of the workpiece to pre-heat the workpiece to an intermediate temperature, and irradiating a second side of the workpiece to heat the second side to a desired temperature greater than the intermediate temperature.
