Application of Hardfacing Wear Plates in Ports
In port operations, hardfacing wear plates are widely applied to diverse handling equipment and yards, especially within bulk cargo handling systems for iron ore, coal and other commodities. Typical components include grabs, hoppers, distributing chutes, coal drop pipes, feed pipes and stacker-reclaimers, which are constantly subjected to heavy impact, abrasion and friction. Lining vulnerable sections with hardfacing composite wear plates effectively extends component service life and cuts downtime for handling equipment maintenance.

Analysis on Failure Causes and Countermeasures of Blast Furnace Distributing Chute
Main failure factors of blast furnace distributing chute are as follows:
- Impact damage from high-fall material flow;
- Sliding abrasion of liner plates by burden materials;
- Shell burnout and cavitation erosion;
- Weld cracking, bolt shearing and substrate tearing caused by thermal stress.
To prevent chute failure and improve its reliability & service life, improvement focuses on two aspects: internal structural design and material selection.
