Manufacturer specializing in wear-resistant alloy lining plates
Our wear-resistant alloy lining plates are professional wear protection components specially designed for ball mills, vertical roller mills, crushing chutes, hoppers and material conveying equipment.
All lining plates are produced with advanced resin sand casting technology and made of premium high chromium cast iron.
Compared with traditional high manganese steel lining plates, they feature higher hardness, superior wear resistance and drastically reduced replacement frequency.

What advantages do the wear-resistant alloy lining plates produced by Shata Machinery have?
In-house resin sand production line with fewer defects
Our factory is equipped with an integrated resin sand mixing and molding production line, where the bonding ratio of molding sand is strictly controlled. All molds are repeatedly verified via trial samples before formal production. With self-developed resin sand molding and staged heat treatment processes, the carbide non-uniformity of lining plates is stably controlled within Grade 3, the volume fraction difference of carbides is ≤3%, and the metallographic dispersion is less than 9%. Fine and dispersed carbides form without coarse mesh clusters. The hardness fluctuation across the entire plate is no more than HRC2, delivering highly uniform martensite matrix structure.
Staged heat treatment balancing high hardness and impact resistance
The staged temperature-controlled quenching and tempering process refines the internal grain structure, solving the common drawbacks of ordinary high-chromium liners - easy cracking at high hardness and insufficient wear resistance with high toughness.
High production efficiency
Mold development and customized sampling start immediately upon receiving drawings, cutting the overall lead time by 40%. Special-shaped parts can also be put into mass production rapidly without delaying customers' construction schedules.
Full-process quality inspection for consistent quality
Data is monitored throughout the whole process from mold samples, initial trial batches to mass production. Test records including spectral composition, hardness, impact resistance and ultrasonic flaw detection are filed for every batch.
All-round customization services
We offer adjustments to alloy composition, lining plate shape, mounting structure and wear-resistant patterns. Custom logos and other personalized requirements are also available.
FAQ
Can the lining plates be used in both dry and wet grinding environments?
Standard chromium-series liners are suitable for dry grinding. For wet mineral slurry processing, we can add copper and nickel alloys to improve corrosion resistance.
Can you provide material test reports?
Yes. Spectral composition reports, hardness test certificates and ultrasonic flaw detection documents can be supplied for every shipment.
What is your annual output capacity of high-chromium wear-resistant castings?
Our factory produces over 5000 tons of resin sand cast high-chromium wear spare parts every year, capable of stably undertaking long-term large-volume procurement contracts.
Why do you adopt resin sand casting instead of ordinary green sand casting for lining plates?
Resin sand molds feature higher strength and thermal stability, resulting in smoother finished surfaces, fewer internal defects and uniform hardness distribution, which greatly extends the service life of liners under severe abrasion working conditions.
We also have green sand casting production lines. Green sand casting is an alternative option for orders with cost-effectiveness priorities.
What is the hardness range of finished Wear-Resistant Alloy Lining Plate?
After complete heat treatment, the hardness stably reaches HRC 58–65, meeting the wear resistance requirements for heavy-duty grinding.
