smooth surface chromium carbide overlay plate - Caster Metallugical Co.

HZY Smooth Surface Chromium Carbide Overlay plate is a bimetal plate that chromium carbide flux cored wire overlaid on the mild steel base plate using submerged arc welding process(modified). There are no cracks and weld beads *For standard/traditional open arc CCO plates which we also produce, please scroll down.

Based on the submerged arc welding process, we improved the process so that the resulting product has no cracks and no weld beads.

Also with the new process, the chemical composition is more flexible.

We also offer Fabrication Services like countersunk holes, stud welding, for the creation of all kinds of wear liners.

Features & Benefits of smooth CCO plates:

1. Last 6 times longer than quenched and tempered steel.
2. Considering the long lifespan and low down time, our solution is more cost efficient.
3. No weld beads.
4. Because of the smooth surface, materials will move easier, less hang up/carry back
   
5. Further improve smoothness by offering shot-blasting surface finish.

Types of smooth surface weld overlay plate:HZY100 and HZY200

We offer 2 options of our smooth chromium carbide overlay plate: HZY100 and HZY200.

HZY200 added (V+Mo+W+Nb+Ni+B+Mn....)4-10% HZY200's chemical composition is Cr.:18-35% ; C: 3.0-5.0% ; Si: <1.0% ;(V+Mo+W+Nb+Ni+B+Mn....):4-10% . Hardness:54-60 HRC. Operating temperature: 350 degree(Celsius).

You can choose based on your own needs...

smooth CCO plates compared with traditional CCO plates(which we also produce):

Type	Surface	Weld beads	Fusion line	Cracks
HZY smooth surface chromium carbide overlay plate/HZY100 and HZY200	Smooth, low friction. Reduced material buildup	No weld beads. So material directional flow is not required	Low dilution with a uniformed fusion line, consistent hardness and micro structure, consistent wear rates	Minimal cracks. Low residual stress between overlay and base plate. Easy for bending and fabrication
Traditional chromium carbide overlay plate	Rough, uneven, material buildup	weld beads. Directional flow over weld beads matters	High dilution and uneven fusion line. Accelerated wear rates when thickness start to reduce	Lots of cracks. High residual stress between overlay and base plate. Not easy for bending and fabrication.

Smooth Surface Wear Plate:HZY100/HZY200：

We also provide polished version: shot-blasting, or mirror finished(hand polished) smooth chromium carbide overlay plates...

The most distinctive feature of our smooth surface bi-metallic plate is that it has no weld beads. This feature makes the mirror-like smooth surface possible. Also,there are no cracks, so it's suitable for finer material transporting.

When using traditional chromium carbide overlay plate, some material will stick to the uneven surface, causing material build-up. This problem will decrease your productivity and increase your cost. Our smooth surface overlay plate is made to solve this problem. It has the combined benefits of regular-steel's smooth surface and chromium-carbide-overlay-plate's toughness. So if you have any such requirement, please let us know.

The new technique is based on and improved upon submerged welding process, the wear resistant property has increased. with the same chrome percentage, you get higher wear resistant score.

Cutting and Forming

caster chromium carbide plates can be easily cut to dimensions using Plasma cutting or water jet cutting. Our overlay wear plates can be rolled as per drawings, and the minimum bending radius is 20 times of the plate total thickness.
Please kindly note that hardfacing overlay plate cannot be machined or drilled by conventional methods. Both countersunk and square holes must be cut by plasma or water jet cutting.

Installation

Commonly, the welding beads shall be installed perpendicular to the materials flow direction in order to obtain maximum wear life. In our company, we offer overlay plates with two different welding bead, normal straight welding pattern and weave pattern. The weave pattern overlay plate enables it much flexible to install either perpendicular or parallel to the material flow direction, make it more wear resistant than normal pattern wear plate, which increases service time of the overlay plate.
