A meta-surface water load includes a waveguide section, a water load section and two meta-surface plates; the water load section is arranged at a rear end of the waveguide section; the two meta-surface plates are arranged opposite on inner walls of two narrow sides of the waveguide section; the water load section includes a metal casing, a ceramic partition, a water inlet and a water outlet; the metal casing is mounted at the rear end of the waveguide section; cooling liquid flows in the metal casing, entering from the water inlet and leaving from the water outlet; the ceramic partition is for separating interior of the waveguide section and interior of the metal casing; a relative permittivity of materials from front to rear of each meta-surface plate is progressively increased, so that microwave in the waveguide section is propagated to the water load section in one direction.

Pure calcium cored wire for steelmaking
The invention discloses a pure calcium cored wire for steelmaking, belonging to the cored wire. The pure calcium cored wire for steelmaking comprises an outer coating layer and a coated core. The coated core is coated in the coating layer; the surface of the outer coating layer is provided with a stand edge which is perpendicular to the tangent of the circular cross section of the outer coating layer; and the outer coating layer has a thickness of 0.75-2.0mm. Compared with the prior art, the capacity of penetrating the steel slag of the pure calcium cored wire for steelmaking is improved greatly, thus the deformation of the pure calcium cored wire due to penetration can be reduced, the pure calcium cored wire can reach the bottom of the steel ladle better, the time of absorbing the calcium strips by the molten steel can be shortened, the formation of the calcium bubbles can be reduced, the splashing of the calcium on the surface of the molten steel can be reduced significantly, and the yield of the calcium can be improved hereby. The pure calcium cored wire for steelmaking has good popularization and application value.
