| description | The invention discloses a steel guide band decarbonizing technological method. The method comprises the following steps that 1) a workpiece to be processed is placed into a vacuum furnace and heated to 1000 DEG C-1200 DEG C; 2) heat preservation is carried out for 2 hours; 3) the workpiece is slowly cooled to room temperature along with the furnace and is taken out of the furnace; 4) the workpieceis placed into a decarbonization furnace and heated to 800 DEG C for decarbonization; 5) heat preservation is carried out for 5 hours; and 6) the workpiece is slowly cooled to room temperature alongwith the furnace. After the steel guide band decarbonizing technology is adopted for decarbonization, the three indexes, namely the carbon content, the hardness and the low-temperature impact, of thesteel guide band meet the technical requirements at the same time, so that the problems that one or two of the indexes are frequently unqualified, and even the three indexes are unqualified are solved, and the percent of pass r |
