The invention offers the high V super-speed steel complex roller and its producing craft. The roller includes roller heart and roller shell, the roller heart uses low metal alloy steel or middle carbon steel to produce, the shell uses high V super-speed steel, whose main element is : C: 1.8--3.5A%, V: 7--12%, Cr: 4--5%, Mo: 2--4%, Ni: 0.5--1.5%, other is Fe. The producing craft is: melt and cast the heart and shell by responding heat way. The roller in the invention has good whet feature, high rate of feature and price, using safely. Fine roller, high strength of combination, no crush in use; it can reduce the stop times. It efficiently increase the roller tenacity and whet feature, solve the problems in the heart leaving foundry, and solve the problems of complicated craft and high cost.
