Reliable material assessment

Computer-aided modelling of the wear behaviour of heavy plate made from high-strength structural steels

Summary: In industrial machinery and equipment subject to wear, heavy plate is used to provide high resistance against the wear. ThyssenKrupp Steel Europe AG supplies a wide range of wear-resistant XAR steels as heavy plate in thicknesses up to 100 mm. Typical ­applications are equipment for the extraction and processing of resources such as coal, ore, rock, etc. The paper reports on a newly developed mathematical model that can be used for a detailed and realistic estimation of the wear behaviour of the steels. This provides effective support for material selection and application.

1 Introduction

To gauge the reliability of wear-resistant steels in structural applications, knowledge of the wear behaviour and the expected durability in the active operating conditions is of paramount importance. The wear behaviour of heavy plate depends both on the material properties, especially the hardness, the properties of the counter body and the ambient medium as well as design constraints.

Calculation-based estimation of the wear behaviour of structural steels exposed to wear as a function of the material properties, the counter material and the ambient conditions is very important...
