为了加速生产进度、提高生产效率、节省电能,我们改革了常规的退火工艺制度,现已在生产实践中获得成功。简单介绍如下:一、改革后的退火方法我们将退火的高合金工具钢Cr 12 Mov毛坯钢料,在860±10℃的退火炉中恒温透烧之后,立即将事先装好铁箱的低合金工具钢CrWMn和T10A毛坯钢料,分别送入炉中进行退火处理,并将炉温控制在800±10℃的温度进行恒温透烧,然后将炉温降至680±10℃等温透烧之后即可关闭电门,待
In order to speed up the production process, increase production efficiency and save energy, we have reformed the conventional annealing process and have succeeded in production. A brief introduction is as follows: First, the annealing method after the reform We will anneal the high alloy tool steel Cr 12 Mov rough steel, 860 ± 10 ℃ in the annealing furnace at constant temperature after burning, immediately prior to loading the low alloy iron box Tool steel CrWMn and T10A rough steel, were sent to the furnace for annealing treatment, and the furnace temperature controlled at 800 ± 10 ℃ temperature constant firing, and then the furnace temperature dropped to 680 ± 10 ℃ isothermal after burning Can turn off the door, stay
