Title:
SINTER CAKE SUPPORT STAND, OVERLAY WELDING WIRE AND OVERLAY WELDING METAL
Document Type and Number:
WIPO Patent Application WO/2011/115307
Kind Code:
A1
Abstract:
Disclosed is a sinter cake support stand which, in high-temperature environments having sintered ore heating temperatures of 1200-1400C, has excellent abrasion resistance and breaking resistance, and corrosion resistance to a high-temperature oxidizing / sulfidizing atmosphere. For that reason, the disclosed sinter cake support stand (10), which is arranged on a sintering pallet of a downward suction sintering machine which produces sintered ore, has a pedestal (11) mounted on the aforementioned sintering pallet and a blade unit (15) extending upward from the pedestal (11); at least at the top edge of the blade unit (15) an overlay welding section (18) is provided, wherein the overlay welding metal constituting said overlay welding section (18) contains C: 3.0-5.0 mass%, Si: 0.8-2.0 mass%, Cr: 10-15 mass%, Mo: 7-10 mass%, and the remaining portion comprising a composition of Fe and unavoidable impurities.
