通过实验论证，研究了高强度钢板采用电阻加热进行热冲压和压力淬火的可行性。在实验中，高强度钢板，SPFC 980 Y，1.2毫米厚，20毫米宽，130毫米长的矩形坯料，它是电阻加热与一对平行的电极放置在彼此相距120毫米，使用具有输入能量控制功能的交流电源。研究了输入能量与加热温度的关系，并对热冲压和压淬性能进行了测试。在热帽形弯曲试验中进行了加压淬火试验，研究了加热温度对回弹和硬度性能的影响。实验结果表明，热冲压和压力淬火使用电阻加热是非常可行的。
The feasibility of hot stamping and press quenching of ultrahigh strength steel sheet using resistance heating was investigated by demonstrating experiments. In the experiments, a rectangular blank of high strength steel sheet, SPFC980Y, 1.2mm thick, 20mm wide and 130mm long was used and it was resistance-heated with a pair of parallel electrodes placed 120mm away from each other, using an AC power supply with a function of input energy control. The relationship between input energy and heating temperature was examined and then hot stamping and press quenching performances were examined. The press quenching was also experimented in hot hat-shaped bending, and the influences of the heating temperature on spring-back and hardness property were investigated. The results of the experiments revealed that hot stamping and press quenching using resistance heating are highly feasible.
