Mining Equipment

GE Patterns; Foundry Induction Hardened Alloy Steel Trackpad Mining Equipment provides the ultimate in wear resistance and toughness that modern mining equipment can at present offer. This is why tracked earth moving & mining equipment that requires long travel life uses this technology almost exclusively. GE Patterns & Foundry also offers Alloy Steel and Manganese trackpad mining equipment that are interchangeable with the OEM. For customers looking for that extra performance, these can be upgraded to induction hardened alloy steel trackpads.

Induction hardening is a type of surface hardening in which a metal part is induction-heated and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly without affecting the properties of the part as a whole.

Induction hardening is a useful method for improving resistance to surface indentation, fatigue and wear that is favoured in comparison with through hardening, which may lack necessary toughness. The process itself involves fast heating by induction with subsequent quenching, creating a martensitic layer at the surface of the workpiece. In the present work, we demonstrate how to simulate the process of induction hardening using a commercial finite element software package with focuses on validation of the electromagnetic and thermal parts, together with evolution of the microstructure. Experiments have been carried out using fifteen workpieces that have been heated using three different heating rates and five different peak temperatures resulting in different microstructures. It is found that the microstructure and hardening depth is affected by the heating rate and peak temperature. The agreement between the experimental and simulated results is good. Also, it is demonstrated that the critical equilibrium temperatures for phase transformation is important for good agreement between the simulated and experimental hardening depth. The developed simulation technique predicts the hardness and microstructure sufficiently well for design and the development of induction hardening processes.

Good Strength and Stretch Resistance
Alloy steel trackpad mining equipment are used as they do not require deformation to increase hardness, The alloy properties have been chosen to ensure minimal deformation in working areas of the trackpad. To improve wear resistance and strength these pads can be induction hardened.

Cost Effective Manganese trackpad mining equipment are now only used by The Best in the industry.
They provide a cost-effective material that gives good toughness and work hardening properties.
GE Patterns & Foundry also offers interchangeable pads in induction hardened alloy steel for
those customers looking for longer life.
