Railway grinding key equipment development status quo-1
2025-05-19
At present, the railway system is the most widely used, the market share of relatively large grinding method for active grinding technology, high-speed passive grinding technology and milling and grinding composite grinding technology. The following three typical rail grinding equipment development status is summarised.
The Self-adaptive Grinding Behaviours of High-speed Rail Grinding under the Sliding-rolling Composite Motions
2025-01-07
The self-adaptive grinding behaviors of high-speed rail under sliding-rolling composite motions focused on optimizing grinding performance and surface quality. High-speed railways, characterized by high operational speeds and light axle loads, often suffer...

Oxidation behavior of rails during grinding process
2024-12-25
During the interaction between abrasives and rails, the plastic deformation of the rails generates heat, and the friction between abrasives and rail materials also generates grinding heat.
Outlook on Grinding Stone Technology for Rail Grinding
2024-12-23
Rail grinding technology can effectively remove rail disease, extend the service life of rails, and improve the comfort, safety and stability of train operation.

The structure design of grinding stone
2024-12-04
One of the main drawbacks of domestically produced grinding stones at present is the tendency to burn steel rails [1]. During the process of rail grinding, the grinding effect of abrasives (sliding, plowing, cutting) and the friction between the binder and rai...

The abrasives of grinding stone
2024-11-25
Grinding stone commonly used abrasives for corundum class abrasives (zirconium corundum, brown corundum, white corundum, etc., such as Figure 11)[1,2] , some super-hard abrasives (CBN)[3] and SiC, WC, etc. Because diamond and transition metal element Fe has st...
