Embodiment 1
[0037] A high-titanium nitride-titanium-silicon alloy cored wire, the cored wire includes a core layer and a steel skin layer wrapped outside the core layer, the core layer is a high-titanium titanium nitride-silicon alloy with a particle size of 3 mm or less Powder, a mesh support layer made of steel or iron is arranged between the core layer and the steel skin layer, and the high-titanium nitride silicon nitride alloy powder is composed of the following elemental components according to mass percentage:
[0038] Al 2.0%
[0039] N 10%
[0040] Mn 4.0%
[0041] Mg 2.0%
[0042] Ti 40%
[0043] P ≤0.1%
[0044] S ≤0.1%
[0045] Si 35%;
[0046] Fe balance.
[0047] The present invention selects sponge iron, sponge titanium, ferrosilicon and ferromanganese to smelt in a vacuum furnace. Under certain process conditions, nitriding is carried out to achieve the best effect of nitriding (specified content), and then cast into ingots. The ingot is broken into a certain part...
