Embodiment 1
[0055] Embodiment one rapid heating + air cooling heat treatment process
[0056] 1) Select ordinary low-carbon aluminum-killed steel series (DC51, DC01, electroplated tin plate and steel strip) as the steel type for rapid heat treatment; prepare the sample, the length of the sample is 260mm, the width is 300mm, and the thickness of the sample is 0.5mm. The sample material is hard rolled plate after cold rolling;
[0057] 2) Put the sample into the heat treatment chamber, clamp it with heating clamps, and heat the sample through the intermediate frequency induction current resistance heater. According to the requirements of the sample annealing process, adjust the output power of the intermediate frequency induction current resistance heater (20% ~95%), the heating temperature is up to 800°C, and the heating rate is up to 500°C / s. Two kinds of gas mixed or N2 mixed with H2, CO, He two gases) for cooling, the cooling rate is 300 ℃ / s, cooled to room temperature; when the samp...
