The disclosure provides methods to avoid over-developed aluminized coatings during hot stamping line stoppages'. The method of treating a blank is provided. The method includes moving a blank througha first section of a furnace at an inter-critical temperature and through a second section of the furnace at a critical temperature greater than the inter-critical temperature before hot stamping theblank. Movement of the blank from the first section to the second section of the furnace is delayed during a hot stamping line stoppage. The blank is in the first section of the furnace for a first time period and in the second section of the furnace a second time period less than the first time period. Also, the first section of the furnace may have a first length and the second section of the furnace may have a second length that is less than the first length. 本公开提供了"在热冲压线停止期间避免过厚的镀铝涂层的方法"。提供了一种处理坯料的方法。所述方法包括：在对所述坯料进行热冲压之前，使坯料在临界间温度下移动穿过加热炉的第一部分并且在大于所述临界间温度的临界温度下移动穿过所述加热炉的第二部分。在热冲压线停止期间，所述坯料从所述加热炉的所述第一部分到所述第二部分的移动被延迟
