Zusammenfassung:The invention discloses a production method for a B-containing steel. The production method comprises the steps that a plate blank of the B-containing steel is obtained; the obtained plate blank of the B-containing steel is rolled, the coiling temperature in rolling is controlled as 660-700 DEG C, the slow cooling time inside a slow cooling pit is controlled as 24-30 hours, and the temperature iscontrolled as 250-300 DEG C when slow cooling is finished; and the plate blank of the B-containing steel after the rolling is molded by hot stamping. By means of adoption of the production method forthe B-containing steel, in the hot stamping working procedure, an oxidized iron sheet is firmly bound to a base body and is not prone to falling off, and the working environment of workers is improved. 本发明公开了一种含B钢的生产方法,所述方法包括,获得含B钢的板坯;将获得的含B钢的板坯轧制,轧制时的卷取温度控制为660~700℃,在缓冷坑内的缓冷时间控制为24~30小时,缓冷结束时温度控制为250~300℃;将轧制后的所述含B钢的板坯热冲压成型。采用本发明的一种含B钢的生产方法,在热冲压工序中,氧化铁皮与基体结合牢固,氧化铁皮不易脱落,工人工作环境改善。
