Cast Ductile Iron Railway Locomotive Brake Block Train Brake Block
Description
Cast iron brake block has been in use on railway vehicles for more than a century in history.
The main advantages of cast iron brake block are:
1. a small friction coefficient affected by the environment and more stable, so it is "all-weather" operational;
2. good thermal conductivity, low thermal damage to the wheels;
3. The coarsening of the wheel surface can obtain more adhesion, which can reduce the mechanical abrasion of the wheel;
4. Durable, low prices.
But the friction coefficient of ordinary gray cast iron brake shoe is small, and with the increase of friction velocity,
friction coefficient decreased rapidly especially when it is in high-speed running.
So ordinary cast iron brake shoes are generally used for low-speed operation of passenger trains.
For cast iron brake used in high speed train, we can improve the performance by increase the content of phosphorus or add
some alloy element.
In fact, it is the high phosphorus cast iron brake block that is widely used now, to avoid the crack, a backing plate is used to reinforce.
