Tip castings and sectors
At the outlet, tip castings protect the end of the shell and hold the nose-ring refractory against clinker at well over 1,000 °C and hot secondary air. When they burn back, the shell overheats and the kiln has to stop.
- Works in
- The kiln inlet and outlet: nose-ring tip castings, outlet sectors and inlet segments.
- Industries
- Cement
- Materials
- Heat-resistant steel
- Size
- Single pieces from 3 kg to 7 tonnes, to drawing
- Supplied
- As cast, or machined to drawing
- Inspection
- Chemistry and hardness on every heat; UT, MPI or DPT and a dimensional report as specified
- From a worn part
- Yes. Send the part or photographs with key dimensions and we will reverse-engineer it
01
How it fails and what we do about it
- 01Burn-back and loss of the tip profileA higher-nickel grade for the hottest positions.
- 02Cracking from thermal cyclingSections and ribs designed to let the casting expand.
- 03Loss of refractory holdAnchoring features cast to drawing.
02
Choosing the grade
Typical values from the governing standards. A metallurgist confirms the grade for your duty with every quotation.
03
What we control
- Chemistry firstChromium and nickel verified on the spectrometer for every heat and recorded against the casting.
- Designed to stay straightRibs and sections arranged so the part can expand without warping.
- Fit-up checkedSegments, hangers and interlocks checked so sets assemble on site without rework.
- Traceable to the heatEvery casting carries its heat number, with the chemistry report to match.
04
For a quotation, send any of these
- Equipment make and model, or the OEM part number
- Drawing, or the worn part or photographs with key dimensions
- The grade used today and the life it gives
- Quantity per set and sets per year
