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.
Chemical compositions of cast iron:

| Phosphorus: | 1.3-1.5% Â |
| Silicon: | 1.5-2.0% Â |
| Sulphur: | 0.1-0.15% Â |
| Manganese: | 0.5-0.8% Â |
Chemical compositions of steel support:

A hydraulic separator is a device used in heating and cooling systems to separate the primary circuit from the secondary circuit. It is typically used in systems that have multiple heat sources or multiple heating zones.
The primary circuit is the part of the system that contains the heat source, such as a boiler or heat pump. The secondary circuit is the part of the system that distributes the heat to different zones, such as radiators or underfloor heating.
The hydraulic separator helps to prevent the mixing of water between the primary and secondary circuits. It creates a buffer between the two circuits, allowing for efficient heat transfer and preventing any potential damage to the heat source.
The hydraulic separator typically consists of a vessel with multiple ports. The primary circuit is connected to one side of the separator, while the secondary circuit is connected to the other side. Inside the separator, there are baffles or other devices that help to create a hydraulic barrier between the two circuits.
By using a hydraulic separator, the flow rate and pressure in each circuit can be independently controlled, allowing for optimal performance and energy efficiency. It also helps to eliminate the need for additional pumps or valves, as the separator itself provides the necessary hydraulic separation.
Overall, a hydraulic separator is an important component in heating and cooling systems, helping to ensure efficient and reliable operation.
