Silicon calcium alloy cored wire (Silicon calcium alloy cored wire) Silicon calcium alloy cored wire is suitable for deoxygenation and desulfurization in steelmaking, which can improve the performance of steel, increase its plasticity, impact toughness, and fluidity of steel liquid. It also has the characteristics of direct dissolution into molten steel and uniform distribution. With the development of the steelmaking industry, the significant increase in high-quality alloy steel and variety steel, the gradual improvement of continuous casting rate, and the continuous improvement of outside furnace refining technology have contributed to the successful development of wire feeding technology. The use of wire feeding technology has greater advantages than powder spraying and direct addition of alloy blocks.
Silicon calcium cored wire is made by processing silicon calcium alloy into powder, wrapping it with steel strip, and then machining it with cored wire. It not only retains the original deoxygenation effect of silicon calcium full alloy, but also increases the depth of calcium reflection, thereby improving the yield of calcium. It is a good deoxygenation product for steelmaking!It is beneficial for adjusting and controlling the content of easily oxidizable elements and trace elements, greatly improving alloy yield, reducing smelting costs, shortening smelting time, and accurately controlling composition. It can play a role in purifying steel and partially changing the properties and morphology of inclusions, improving the quality of molten steel and improving the casting state. The cored wire can be divided into two types: internal withdrawal type and external release type. The mechanical equipment required for wire feeding is simple and reliable, with a small footprint.
Core wire packaging quality: The packaging shoes are firm, without powder leakage, seams, creases, virtual packages, or empty packages. The powder core density is uniform, and the surface is smooth and free of oil stains.
