Mining, Quarries/ Earthmoving
Part: Buckets
Base material: Un/low alloy steel
Problem:
Wear on bucket and bucket teeth due to abrasion
,friction and impact by coal, sand, stone etc.
Equipment looses efficiency, causing increase in
operating costs.
Solution:
Protect bucket lips, sides and other wear areas by
applying a wear resistant high alloy Chromium
Carbide material.
Welding process: SMAW (Stick electrodes)
Welding material: A) ARCWEL 600, B) ARCWEL 630
Use ARCWEL 630 for severe abrasion
JAW CRUSHERS –CRUSHER JAW PLATE
Used to crush (reduce) hard materials such as coal, stone etc.
Crushers are normally made form a wear resistant Manganese steel.
Problem:
The high impact and compression causes the Jaw
plates to wear out and the crusher looses crushing efficiency.
Solution:
Weld repair
Welding process: SMAW (stick electrodes)
Welding material: A) ARCWEL 355 –SMAW
HAMMER MILL CRUSHER (COAL PACTORS )
widely used crusher system Made from austenitic manganese steel or low alloy cast steel
Problem:
The Hammers crushing the raw materials
are subject to extreme impact/pressure
and abrasion and tend to suffer wear and
tear
Solution:
Rebuild worn hammers by using one
of the following Welding materials.
ARCWEL 355 for restoring dimension
and thereafter apply 2 layers of ARCWEL
630 or 655 for maximum protection
Wear on Crusher Housing (Bearing)
Repair welding : ARCWEL 350/355
Machinable weld deposit
Machine: EXCAVATOR
Part: Track pads
Base material: Low alloy cast steel
Problem:
Wear on truck pads due to friction and pressure.
Equipment looses efficiency, causing increase in operating costs.
USE ARCWEL 300 or 355 FOR REPAIR
Wear protection of coal mining buckets with
ARCWEL 630
Coal cutter Bit hardfacing
ARCWEL 630/655
Coal mining machine protection
ARCWEL 630/655
