| Abstract: | The article introduces the working principle and the main instrument of the plasma system. By analyzing the consumption of energy medium and electricity, as well as effect on tundish refractory, we finally find out the best matching of plasma power with the gap between the spear head and level of melten steel. Some special steel grade can be cast at constant low temperature, and crystal structure of slab become thinner and more homogeneous. |
