A process for the preparation of a high-alloy steel casting material with a fine grain structure of the workpiece.

摘要

A high-alloy, heat-resistant, a chromium-containing cast-steel material should be reliable in terms of processing with an evenly distributed, can be produced by a fine structure.For this purpose, a seeding the steel casting melt with an inoculant, which contains the following elements:Ce and / or samarium and / or another element from the group of the lanthanides: 8,0 - 18,0%.-%Si: 15,0 - 25,0%.-%Cr: 25,0 - 40,0%.-%Fe: at least 90% of the remaining portion.
