One Of High Level Metals Alloys Cored Wire

A kind of magnesium-silicon-calcium alloy cored wire and preparation method thereof, a composite wire with a set length composed of a core and an outer skin, the mass percentage of the core material component of the cored wire is as follows: Mg is 18~30%, Si is 30~45%, Ca is 515%, H2O≤0.5%, Fe allowance, particle size distribution: 0.53mm 10%; 0.61mm 20%; 0.82mm 70%, which is made of magnesium-calcium silicon alloy as raw material, through magnesium-calcium silicon alloy die-casting into appropriate particle size and particle size according to the composition needs of the production of magnesium-silicon-calcium alloy cored wire, the alloy cored wire has strong deoxidation, desulfurization ability, through the wire feeder to add the cored wire to the bottom of the ladle, so that the molten steel is more pure.

1.The utility model relates to the technical field of silicon-calcium alloy cored wire, specifically a rewinding device for the production of silicon-calcium alloy cored wire, comprises a frame body, the frame body comprises a winding frame, the inner side of the winding frame is provided with a wire spool, one side of the winding frame is provided with a frame, and the inner side of the frame is provided with a wire body. The utility model discloses by setting the sponge on the surface of the connecting roller, when the line body is rewinded, the line body is in contact with the sponge first, the sponge can remove the dust attached to the surface of the line body during contact, the dust can be avoided to be wound together with the wire body and remain on the winding spool, the cleanliness of the winding spool surface is guaranteed, so that the quality of the line body rewinding will not be affected, because the spring has a resilient quality, when the line body is relaxed, the telescopic column drives the connecting roller to rise under the rebound effect of the spring, It can maintain close contact between the surface of the thread and the sponge, which can not only achieve cleanliness but also ensure the tension of the thread.
