Abstract

PURPOSE: To improve the crack resistance through precipitation of graphite with addition if inoculant to melted material in casting an adamite roll material with a specified composition.
CONSTITUTION: Melted material for adamite roll containing 1.5-2.3% C, 0.4-0.7% Si, 0.6-0.9% Mn, 4.0% > Ni, 1-3% Cr, 0.9% > Mo and Fe for th rest is cast into a roll. Here, a Si affiliated inoculant such as Fe-si, Ca-Si and Zr-Si agents and metal Si is added to the melted material at a rate of 0.2 to 0.5% in terms of pure Si. A part of metal carbide contained in the adamite roll material is decomposed and percipitated in the form of graphite. The graphite thus percipitated absorbs cracks to check the transmission thereof, thus improving the crack resistance.
