PROBLEM TO BE SOLVED: To inhibit generation of edge-cracking on an edge part of a material to be rolled, improve production efficiency, and further improve an yield of products, when hot-rolling a continuously-cast slab of high-Ni alloy steel containing≥20 and≤85 mass% Ni. SOLUTION: In a method for hot rolling a continuously-cast slab of high-Ni alloy steel, the rolling is conducted by using only edger rolls for at least one pass including the 1st pass of rolling, in a rolling mill provided with at least one set of edger rolls and one set of horizontal rolls.
