Small flake liner
The small-flake liner is a protective liner on a flake-type chain grate. It fits between the small-flake chain and the grate frame and separates the two while taking the wear.
Where it fits and what it does
The liner is laid along the direction of chain travel on the fixed frame, separating the moving chain from the frame and reducing direct wear between them. Once grooves have worn into its surface, the chain tends to run off line, so the liner is one of the items checked during maintenance. It is fixed to the original hole positions during assembly and kept on the same centre line as the chain and the front and rear wheels.
Material and temperature resistance
The liner can be supplied in grades between HT200 and RTCr16 according to the working conditions, with temperature resistance from 480℃ to 900℃.
| Material | Temperature resistance | Characteristics |
|---|---|---|
| HT200 | 480℃ | Simple process, low cost |
| HT250 | 520℃ | High strength, wear- and heat-resistant |
| RTCr5 | 700℃ | Good oxidation and corrosion resistance |
| RTCr16 | 900℃ | Good oxidation and corrosion resistance |
Supply and matching parts
The partner factory handles dispatch, and we can supply the small-flake liner plus chains, pins, clamping clips and other parts from the same series, and can make dimensions and material to drawings. For selection, just give us the grate model and the dimensions of the old part, and we can help check how the parts match.
