The invention relates to an alloy core-spun yarn, in particular to a rare earth, niobium, vanadium and boron-contained titanium silicon nitride alloy core-spun yarn. The core-spun yarn comprises a core layer, and a steel skin layer wrapped at the external of the core layer; the core layer is rare earth, niobium, vanadium and boron-contained titanium silicon nitride alloy powder with a particle size of below 3 mm; a netty support layer manufactured by steel or iron is arranged between the core layer and the steel skin layer; and the rare earth, niobium, vanadium and boron-contained titanium silicon nitride alloy powder consists of the following element components in percentage by mass: 1.0-2.5% of Al, 10-25% of N, 2.5-5.0% of Mn, 1.0-2.5% of Mg, 25-40% of Ti, 25-35% of Si, 0.5-1.0% of Nb, 0.5-1.0% of V, 0.5-1.0% of B, 1.0-2.0% of rare earth element, P not more than 0.1%, S not more than 0.1%, and the balance of Fe. The alloy powder is added in microalloyed steel by a core-spun yarn method, so that the problem
