Hot screen plates are primarily used for the high-temperature screening of sintered ore, requiring long-term operation under conditions involving thermal shock, ore impact, and severe abrasive wear. As high-temperature sinter passes over the screen surface, the edges of the apertures, the feed end, and the support areas are prone to wear, deformation, and cracking, leading to reduced screening efficiency and frequent downtime for replacements.
\nReinforcing the screen surface through the use of heat- and wear-resistant plates, high-temperature castings, and hard-facing overlays can enhance resistance to high-temperature wear and thermal fatigue, maintain stable aperture dimensions, and reduce aperture clogging and mis-screening. Data indicates that hot screens, cold screens, feed chutes, and conveyor transfer points are typical areas of wear in the sintering process.<\/p>\n
