STEEL SHEET FOR PLASMA DISPLAY FIXING PLATE, METHOD FOR PRODUCING STEEL SHEET FOR FIXING PLASMA DISPLAY, AND PLASMA DISPLAY FIXING PLATE

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive plasma display fixing plate having excellent corrosion resistance or heat radiability.;SOLUTION: A slab composed of a continuously cast slab is subjected to hot rolling at a high draft, and is thereafter rapidly cooled, so as to be a hot rolled sheet having a structure where martensite is dispersed into ferrite. Next, the hot rolled sheet is subjected to primary cold rolling, is annealed, is further subjected to secondary cold rolling, and is galvanized, and a chemical conversion treatment layer of improving its corrosion resistance or heat radiability is formed thereon.;COPYRIGHT: (C)2007,JPO&INPIT
