Explosion-welded bimetal wear plate

Engineered to the drawing.

Not a catalogue: wear plate is a wear allowance, a load path and a bolt pattern before it is a material. We quote the build-up from your duty and your structure, then cut, drill and form to the drawing you send.

Bimetal wear plate cut and counterbored to drawing, racked after inspection
What the plate has to survive

Three numbers decide whether a liner lasts

Not the grade name. The wear allowance, the bond and the hardness you can prove on the plate in front of you.

4+4 to 10+10 mmBuild-up range, wear layer plus backing. Set by duty, not by what is in stock.
500-600 N/mm²Interface shear strength on the bond test, all three grades.
54-64 HRCWear-face hardness, checked on every plate with a Leeb tester.
The series

Three grades, one welding line

BT-CW-B

Standard wear

58-62 HRC wear face, 4-6 mm layer, carbon steel backing from 25 mm. Chutes, hoppers and transfer points under sliding abrasion.

BT-CW-BS

Stainless backing

54-58 HRC wear face, stainless backing from 25 mm. Wet, salty or corrosive material where a carbon backing would rust out first.

BT-CW-BE

Heavy impact

60-64 HRC wear face, 8-10 mm layer, backing from 32 mm. Coarse lumps, mill housings, bearing seats, structures that can carry the weight.

Where a drawing calls for a proprietary grade, send the hardness and case depth written on it. We check the section against those figures before quoting, and say plainly if the section will not hold.

Selection

Pick the build-up by what you are replacing

Two questions settle it: how long the old liner lasted, and how much weight the wall or bucket can carry. Everything else is detail.

Build-upWhere it belongs
4+4 mmLight sliding abrasion, small chutes, low headroom
6+4 mmGeneral chute and hopper linings, moderate impact
8+6 mmCoarse material, longer intervals between stops
10+10 mmHigh wear allowance, large lumps, heavy structures
From enquiry to crate

How an order runs

  1. Drawing and dutyOutline drawing or a photo of the worn plate with its overall size, the material handled, lump size, drop height and whether it runs wet or dry.
  2. Section checkWe check the build-up against the duty and the structure, then quote grade, thickness and weight.
  3. Welding and flatteningExplosion welding, then flattening and stress relief so the plate sits flat on the structure.
  4. Cutting, drilling, formingPlasma or waterjet cutting, drilled and countersunk to the pattern, rolled or pressed where the drawing calls for it.
  5. Inspection and packingHardness checked on the plate, dimensions checked against the drawing, plates marked and crated for sea freight.
Where it goes

Bulk material handling, and the places it eats steel

MiningChute and bin liners, truck bed plates.
CementFeed chutes, clinker transfer points.
SteelSlag paths, mill housings, bearing seats.
CoalBunkers, hoppers, wagon tippler linings.
PortsGrab buckets, hopper walls, conveyor skirts.

Next step

Send the drawing. We will send back a section.

A PDF or a phone photo is enough. We reply within one working day with the build-up, the weight and what we need to confirm.
