This bi-metallic construction delivers unparalleled performance where extreme abrasion and significant impact loads coexist. They are the preferred solution for safeguarding critical edges and surfaces on heavy machinery operating in harsh environments like mining, quarrying, and bulk material handling, significantly extending component life and reducing costly downtime.
Bi-Metal Synergy:Combines exceptional surface hardness (typically HRc 60+) for abrasion resistance with the ductility and impact strength of a robust steel backing.
Hot Cast Bond:Ensures a metallurgical bond between the wear face and backing steel, eliminating delamination risks and maximizing strength integrity under heavy impact.
Superior Abrasion Resistance:The hardened alloy face provides outstanding protection against severe wear from sand, rock, ore, and other abrasive materials.
High Impact Strength:The tough steel backing absorbs shock and impact forces, preventing cracking or spalling, crucial for applications like loading and dumping.
Optimized Design:Available in various profiles and thicknesses to suit specific equipment models (e.g., loader buckets, excavator buckets, crusher liners, chutes).
Cost-Effective Protection:Dramatically extends the service life of underlying base metal structures, reducing replacement frequency and total operating costs.
Leading edges and lip sections of excavator, loader, and backhoe buckets.
Wear liners and shrouds for crusher chambers, chutes, hoppers, and transfer points in mining and aggregate processing.
Protection for dozer blades, grader moldboards, and ripper shanks.
Wear parts on dredge cutter heads, tunnel boring machines (TBMs), and screening equipment.
Any application requiring high abrasion resistance coupled with impact toughness.
Q: How does the hot-cast process benefit the shroud compared to welding hardfacing?
A: The hot-cast process creates a true metallurgical bond over the entire interface, offering superior strength and eliminating the heat-affected zone (HAZ) cracking risks associated with extensive welding. It also allows for thicker, more consistent wear layers.
Q: Can these shrouds be welded onto my existing equipment?
A: Yes, the steel backing is specifically chosen for its weldability. Standard welding procedures for the backing material can be used for installation.
Q: What is the typical hardness range of the wear face?
A: The wear-resistant alloy face typically achieves a hardness of HRc 60-65 or higher, depending on the specific alloy composition.
Q: Are custom shapes and sizes available?
A: Yes, many manufacturers offer custom fabrication based on customer drawings or worn part samples to ensure perfect fitment.
Q: How do bi-metal shrouds compare to manganese steel?
A: Bi-metal shrouds generally offer significantly higher initial abrasion resistance than austenitic manganese steel and maintain their hardness better under high-impact conditions, leading to longer wear life in severe abrasion/impact scenarios. Manganese steel relies on work-hardening, which can be inconsistent.
