AG-2号颗粒保护渣在我国首次研制成功。颗粒保护渣的成型工艺特点是:工艺设备简单、操作容易、生产过程中不会产生有害气体污染环境和人体。经生产实践证明:颗粒保护渣的性能良好,钢锭的表面质量得到改善,低倍检验合格率是稳定的。AG-2号颗粒保护渣能够较好地解决粉尘污染,如进一步完善它的成型工艺,达到消除粉尘污染是完全可能的。 AG-2 particle protection slag was successfully developed in China for the first time. Molding powder particle molding process features are: process equipment is simple, easy to operate, the production process will not produce harmful gases pollute the environment and the human body. The production proved that: the performance of particle flux good, the ingot surface quality has been improved, low pass test pass rate is stable. AG-2 particle powder can better solve the dust pollution, such as further improve its molding process, to eliminate dust pollution is entirely possible.
