三、平均吸收脉冲热功率密度q_F、熔潭下辊面温升分别与q_F、及物性参量之间关系要导出非晶带厚的普遍联系规律,必须引出这三个方程,但碍篇幅限制,导出过程将于另文论述。根据热力学第一定律,结合非晶带形成过程的特点,可导出熔潭对其下转动辊面形成的脉冲热流平均吸收热功率密度q_F方程为:
Third, the average absorption pulse thermal power density q_F, melt pool surface temperature rise and q_F, respectively, and the relationship between physical parameters to be derived from the general rules of contact with amorphous thick, must lead to these three equations, The export process will be discussed elsewhere. According to the first law of thermodynamics and the characteristics of the formation process of the amorphous zone, the average absorbed heat power density q_F of the impulse heat flux formed by the molten pool on its lower rotating roll surface is:
