Steel wear solutions
Raw Material Handling System Wear Solutions
Wear protection for abrasive raw material handling operations.
Raw Material Handling system
Zone Introduction
Raw Material Handling System (RMHS) is the first stage of steel production. It continuously supplies essential raw materials like iron ore, coke, coal, and limestone to Sinter Plant, Coke Oven and Blast Furnace.
If RMHS stops → Entire steel plant stops.
High reliability is crucial for uninterrupted steel production.
How wear happens
Process Description
Raw materials coming from railway wagons, trucks, or mines are unloaded into hoppers and transferred through feeders, conveyor belts, and chutes across long distances.
These materials arrive in different sizes — from large boulders to sharp fines. They are highly abrasive in nature and often contain hard minerals like silica.
Even thick steel plates wear thin, bend or crack. Since RMHS runs 24/7, any stoppage directly impacts entire production.
- Large pieces fall from a height High impact force
- Fine particles slide continuously Intense abrasion
- Moisture converts dust into slurry Abrasion + Corrosion
- Irregular shapes cause Gouging of liners
- Vibration and loading cycles Fatigue cracks
