It outlines the chemical composition, mechanical properties, and tolerances for hot-rolled steel bars and sections used in construction, including the rails.
In addition to these standards, Australian rail manufacturers must also adhere to various regulations, such as the Australian Rail Track Corporation’s Network Rules and Procedures. These regulations cover various aspects of rail safety, including track inspection, maintenance, and operation.
Types of Australian Standards Rails
There are several types of Australian Standards Rails available, each designed for specific applications and environments. The four most commonly used types of rails are AS60, AS68, AS86, and AS108.
AS60 rails are typically used in light-duty applications such as industrial sidings, temporary tracks, and mining operations. They have a minimum weight of 60 kg/m and are 60mm high, making them suitable for areas with lower traffic loads.
AS68 rails are heavier than AS60 rails and have a minimum weight of 68 kg/m. They are 68mm high and are typically used in applications such as mainline tracks and heavy industrial areas.
AS86 rails are even heavier than AS68 rails, with a minimum weight of 86 kg/m. They are 86mm high and are used in high-traffic areas such as ports, intermodal terminals, and heavy haul railway lines.
AS108 rails are the heaviest of the four types, with a minimum weight of 108 kg/m. They are 108mm high and are used in high-speed railway lines and heavy haul applications.
Each type of rail has its unique set of pros and cons. For example, AS60 rails are lightweight and easy to install, making them ideal for temporary tracks and mining operations. However, they are not suitable for high-traffic areas due to their lower weight and smaller size.
On the other hand, AS108 rails are incredibly durable and can withstand heavy traffic loads, making them ideal for high-speed and heavy haul applications. However, they are also the most expensive and challenging to install due to their weight and size.
AS68 and AS86 rails fall somewhere in between, with a balance of weight and size suitable for a variety of applications. AS68 rails are an excellent choice for mainline tracks and heavy industrial areas, while AS86 rails are ideal for high-traffic areas such as ports and intermodal terminals.
Manufacturing Processes for Australian Standards Rails
Manufacturing Australian Standards Rails involves several steps and quality control measures to ensure their compliance with AS 1085 and other relevant standards. The rails are typically manufactured using either hot-rolled or cold-worked processes.
Hot-rolled rails are made by heating a steel billet and then rolling it through a series of rollers to create the desired shape and size. This process results in rails with a slightly curved profile and a rougher surface texture. Hot-rolled rails are typically used for heavy-duty applications such as mainline tracks and heavy industrial areas.
Cold-worked rails, on the other hand, are made by cold-forming steel billets into rails using a series of rollers. This process results in rails with a more precise profile and a smoother surface texture. Cold-worked rails are typically used for light-duty applications such as temporary tracks and mining operations.
During the manufacturing process, strict quality control measures are in place to ensure the rails meet the required standards. These measures include testing the steel composition, inspecting the rail dimensions and surface quality, and performing destructive and non-destructive testing to ensure the rails meet the required strength and durability requirements.
The quality control measures for Australian Standards Rails also include inspections at various stages of the manufacturing process, including inspections of the raw materials, inspections during the rolling process, and final inspections of the finished rails.
Furthermore, Australian Standards Rails must undergo extensive testing to ensure they comply with AS 1085 and other relevant standards. This includes testing for straightness, surface quality, rail profile, rail wear, and rail hardness.
