Lightweight Fan-Shaped Brick
For furnace use, these bricks are made from high quality tabular alumina and mullite, with a sillimanite-based composite matrix. We add rare-earth oxides and other special additives. The mix is pressed under high pressure and fired at high temperatures. The result is good strength, thermal stability, and refractory performance.
Danyang Dingfeng Industrial Furnace Co., Ltd. is one of the most reliable manufacturers and suppliers of lightweight fan-shaped brick in China. If you're going to wholesale durable lightweight fan-shaped brick made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Product Definition
Lightweight fan-shaped bricks are used to build circular furnace linings – think arches, vaults, and curved walls inside industrial furnaces. The fan shape lets the bricks fit tightly around a curve. Not the same as standard partition bricks for building walls. That's a different product.

Working Principle
You install the fan-shaped bricks side by side around a curve. The tapered shape wedges them together tightly. Minimal gaps. The structure stays stable even when hot.
The lightweight fan-shaped brick body is porous but strong. That porosity reduces heat flow through the lining. Heat stays in the furnace. The outside shell stays cooler. Better thermal efficiency, less energy wasted.
Features
Weight savings
These lightweight fan-shaped bricks are lighter than dense firebrick. That means the furnace structure doesn't need to be as heavy. Less steel, less reinforced concrete. One customer saved 15% on his foundation cost just by switching to lightweight fan bricks for the arch.
Space savings
Because the bricks are lighter, you can use a thinner lining for the same insulation value. That gives you more usable inside space. Or a smaller overall footprint.
Easy to install
The fan shape locks them in place. You don't need as much mortar. A skilled mason can lay them fast.
Applications
Industrial furnaces
Heat treatment, annealing, tempering, carburizing. Any furnace with a curved roof or arch benefits from these bricks.
Metallurgical industry
Steel reheating furnaces, holding furnaces, non-ferrous melting. The bricks hold up to thermal cycling.
Ceramic industry
Tunnel kilns, shuttle kilns, roller hearth kilns. The curved arch roofs are standard there.
Petrochemical industry
High temperature reactors and thermal processing equipment.
Power generation
Boiler insulation and waste heat recovery.
