自有气体强度渗氮以来,始终摆脱不了长时间保温渗氮的局面,生产效率甚低。为提高渗氮速率,延长设备使用周期,我们在自制渗氮罐时,在罐内壁涂覆一层耐高温物质,在渗氮温度不变,没有任何催渗剂的情况下,每小时渗层可达0.1mm左右,同原来渗氮工艺相比,其优点是大大提高了渗氮速率,缩短了渗氮周期,减少了变形,提高了工效,节约了能源,降低了
Nitriding since the strength of its own gas, and always can not get rid of a long time insulation nitriding situation, the production efficiency is very low. In order to improve the nitriding rate and extend the service life of the equipment, when we make a nitriding tank, we apply a layer of refractory on the inner wall of the tank. At the same nitriding temperature and without any catalyst, Up to about 0.1mm, compared with the original nitriding process, which has the advantage of greatly improving the nitriding rate, shorten the nitriding cycle, reduce deformation, improve work efficiency, save energy and reduce the
