The invention discloses an atomizer for spray forming of high-melting-point alloy deposit billets, and relates to an atomizer. The invention solves the problem that deposit billets prepared by the atomizer have large grains and low compactness, and cannot be subjected to spray forming to form the high-melting-point alloy deposit billets. A thermal insulating crucible and an atomizing cone are fixedly connected through an atomization plant; the upper part of an upper atomizer is provided with a 35-degree inner taper hole, while the lower part is provided with a step hole communicated with the inner taper hole; the outer wall of the upper atomizer is provided with first external threads; the center of a lower atomizer is provided with first internal threads, a first cylindrical hole and a second cylindrical hole in turn from top to bottom; the side wall of the first cylindrical hole is provided with a second internal threaded hole; the first external threads are screwed in the first internal threads; a cavity is formed between the first cylindrical hole and the outer wall of the step hole; a gap is reserved between the second cylindrical hole and the outer wall of the step hole; andboth the upper atomizer and the lower atomizer are made of graphite. The atomizer is suitable for preparing the high-melting-point alloy deposit billets through spray forming.
