These high-alumina bricks work really well in steel plants' pellet furnaces because they have five main benefits: they can handle temperature changes of up to 1600°C without breaking, they are very stable chemically in iron ore pelletizing atmospheres, they are stronger mechanically so they can hold up under heavy loads, they don't rust in acidic or basic slag conditions, and they last longer, so they don't need to be maintained as often. The alumina content in these refractory materials ranges from 48 to 85%, which makes them the best choice for pelletizing operations in terms of both thermal properties and cost-effectiveness.
Figuring out how well high-alumina bricks work in pelletizing processes
Pellet furnace refractory systems have to work in tough conditions that call for special materials. Bricks that are heated to high temperatures and have a lot of alumina in them are very resistant to thermal cycling. Modern pelletizing plants use temperatures above 1350°C to process iron ore concentrates, which makes the conditions tough for materials used to line furnaces. The chemicals that make up these refractory materials have a direct effect on how well they work. The grades of alumina used in refractory materials usually range from moderate to ultra-high. Depending on where it is used in the pelletizing furnace system, each grade has its own unique benefits. Steel plants all over the world know how important it is to choose the right refractory lining solutions. The properties of thermal conductivity affect how much energy is used, and wear resistance bricks keep downtime to a minimum. Chemical stability makes sure that campaigns last for a long time, so high density bricks are necessary for long-term operations.
