 High Phosphorus Railway Brake Shoe Cast Iron HT200 Plain / Color Rail Parts
 
Product Name: cast iron brake block
 
HS: 86082 9000
 
Brief introduction
Our cast iron brake block enjoys many advantages including hardness, impact strength and so on. It consists of two parts, the cast iron and the steel support. Both the surface and core of the cast iron have the hardness within the range of 197< HB< 255.
When facing subsequent impacts to the brake block or brake shoe, the steel support must remain intact and attached to the iron places. The connection bridge may possibly become detached but should not show any soundness defects. Separated from the brake shoe, the support must be able to withstand the bend test with cracking or breaking.

Theory
 
The brake shoe are located on the wheel tread.
when braking, two pieces of brake block clamp the wheel to make it stop.
 
 
Process: Casting
 

 
Test procedure

 Vernier caliper or other methods are used to test the dimension of the brake block. Laboratory test
