PRO 6000 Earth Moving Equipment
UltraClad PRO6000 is perfectly suitable for hard facing applications which requires impact resistance, high abrasion resistance and ability to withstand higher temperatures.
The temperature rating is up to 750°C. UltraClad range includes HTCC which is manufactured with a mix of Tungsten, Chromium Carbides and Boron Carbides in a Nickel and Silicon matrix.
The REXLINE™ Bucket loader wear plates (CCO) will outlast quenched and tempered steels by up to 12 times and white iron by up to 4 times.
The wear plates maintains the efficiency of chutes, bins, hoppers, buckets and other material handling equipment because it is quickly polished by abrading materials.

Case Study
- The client, was in dire need for a high wear resistant material for the sizing crusher. The drum inside the crusher wears out quickly hence resulting in breakdowns and high maintenance intervals. Considering these equipment’s are highly performance driven and tonnage achieved is of importance, a breakdown is last thing needed.
- REXLINE™ has developed its Chromium Carbide Steel Liner over years of reengineering and tests conducted over its chemical composition based on client requirements. REXLINE™ engineers suggested this product based on similar past applications.
- Considering the Shape and manufacturability, these liners were welded on submerged arc welding station and were curved to suit the drum profile. As part of its services, REXLINE™ conducted QA/QC and Dimensional Checks to ensure the product is top quality and can be installed on the crusher with ease and each liner can be interchanged

Ni HARD BILLETS – Liners – Buttons- Bars
REXLINE™ – Laminated Wear Blocks are unique wear resistant materials in that they combine very high wear resistant qualities of white iron (ASTM A532 15/3CrMo, 700BHN – 63HRc) with a weldable & high impact toughness mild steel through a metallurgical bond to create a product that has a exceptional resistance to impact and abrasion.
Ni-Hard material also comes in Hard skirt format with different shapes and sizes depending on the application. The additional chromium content enables the skirts to withstand extended and continuous abrasion in the application.

Project Detail
For this project, we help our client to increase the service life of one of their chutes. A chute is an equipment which is normally used conveying goods in the mining industry to transfer and channel from one conveyor system to another.
The wall of the chute wears out fast during this process because of the ores colliding and hitting against the it. We recommend them to use the REXLINE™ Ni-Hard liners for protection which can resist that high amount of abrasion and impact.
The side skirts on the equipment was 20 mm long and the client used to get flex and bows in the skirts due to the long length. After discussing with USH engineering team, the best solution to prevent this problem from happening again is by implementing reinforce steel strips in the casting to hold the shape of the skirts and prevent them from bowing and bending.
