Products Description
The silicon nitride manganese cored wire for vanadium microalloyed steel nitrogen addition belongs to the refining outside the molten steel furnace, especially the cored wire for vanadium microalloyed steel nitrogen addition. It is composed of a wire core and an outer layer, and its characteristics are that the wire core is a granular silicon nitride manganese alloy with a particle size of 0.20-1.2mm; the outer layer is a low-carbon steel strip with a thickness of 0.32-0.45mm, tightly coated on the wire core; the cored wire is a round strip with a diameter of Ф9-Ф16mm. The cored wire is used in the process of electric furnace-LF furnace-continuous casting steelmaking or in the process of electric furnace-LF furnace-VD furnace-continuous casting steelmaking. The advantages are novel concept, reasonable structure, tight and firm coating; silicon nitride manganese is fed into the deep part of the molten steel, nitrogen loss is reduced, and the nitrogen recovery rate is more than doubled (≥42%); the vanadium microalloyed steel produced has good quality, and its mechanical properties are equivalent to those of adding vanadium nitrogen alloy to increase nitrogen, the steelmaking cost is reduced, and the economic benefits are significant.

Products cooperation picture
1.A new type of processing equipment for spheroidized cored wire used in ductile iron relates to the technical field of cored wire processing equipment. It comprises a mixing barrel and a supporting leg installed on the outer wall of the mixing barrel, a top cover is threadedly connected to the top of the mixing barrel, and a through hole is opened on the top of the top cover, a fixing plate is installed on the outer wall of one end of the top cover, a fixed material feeding structure is installed on the top of the fixing plate, and a mixing and cleaning structure is installed in the mixing barrel, and the fixed material feeding structure is used to quantitatively add cored wire powder and chemical elements into the mixing barrel. The utility model can control the amount of cored wire powder added by setting the fixed material feeding structure, ensure that the amount of powder added each time is uniform, avoid affecting the quality of ductile iron due to insufficient or excessive feeding, and quantitatively add chemical elements into the mixing barrel to ensure that each element is evenly distributed during the mixing process, avoiding the situation of uneven chemical composition in ductile iron due to uneven mixing.
