Composite And Casting Railway Brake Blocks High Friction For Braking
HS: 86082 9000
Application:Heavy Duty Truck.Train.Bus,Automobile,petroleum drilling machine.
Material:
1. Cast iron HT200 Refer to standard GB/T 9439-1988
2. Composite material
1) rail way composite Brake shoe Material:
Composite material,high friction composite brake shoe,low friction composite brake shoe
2) Advantage:
-- Composite friction material bearing high energy braking;
-- High coefficient of friction and stability,
-- small heat fade for coefficient of friction,
-- Temperature insensitiveness,
-- Develop according to the samples or drawings
-- Certification:ISO9001-2000
Samples:
We can provide a variety of Locomotive Brake Shoe, all of our products are qualified by ISO with high quality standard.
Locomotive Brake Shoe
The brake is fitting for the locomotive which speed is less than 100km / h
There are three types as following:
1. Grey Cast Iron
2. High Phosphorus Cast Iron
3. Alloy Cast Iron
A. The chemical composition and mechanical properties
Material | Chemical Composition% | Tensile Strength Mpa | Hardness HBW10/3000 | |||
C | Si | Mn | P | |||
Grey Cast Iron | 2.9-3.5 | 1.8-2.2 | 0.6-1.2 | ≤1.0 | ≥150 | 179-255 |
High Phosphorus Cast Iron | 2.8-3.6 | 1.5-2.2 | 0.8-1.2 | 1.3-2.0 | ≥150 | 179-255 |
Alloy Cast Iron | 2.8-3.6 | 1.28-1.8 | 1.2-1.9 | ≤0.15 | 200-320 | 200-260 |
B. Average Friction Coefficient
Braking speed Km/H | Grey Cast Iron | High Phosphorus Cast Iron | Alloy Cast Iron |
100 | 0.1 | 0.13 | 0.1 |
80 | 0.11 | 0.15 | 0.11 |
Similarity
