Precise argon blowing stopper rod and preparation method thereof
The stopper rod comprises a body, a breathable core and a rod head, a first blowing hole is formed in the center of the body, the breathable core is fixedly arranged at the front end of the first blowing hole, the front end of the breathable core extends into the rod head, the bottom of the rod head is fixedly connected with the front end of the body, a second blowing hole is formed in the center of the rod head, and the front end of the breathable core is inserted into the second blowing hole. The breathable core is communicated with the first blow hole and the second blow hole, and the outer wall of the rod head is coated with a high-temperature-resistant material. According to the stopper rod capable of blowing argon accurately, it is guaranteed that the breathable core is installed in place, the quality of molten steel is improved, and the blowing flow and the back pressure are stable.
本发明公开了精确吹氩的塞棒，包括：本体、透气芯和棒头，本体中心设置第一吹气孔，第一吹气孔的前端固定设置透气芯，透气芯的前端伸入棒头，棒头的底部与本体的前端固定连接，棒头的中心设有第二吹气孔，透气芯的前端插入第二吹气孔，透气芯连通第一吹气孔和第二吹气孔，棒头外壁涂覆耐高温材料。本发明的目的在于提供了一种保证透气芯安装到位、提高钢水质量、吹气流量与背压稳定的精确吹氩的塞棒的精确吹氩的塞棒。
