Refractory Bricks – No.1 Fire Brick Manufacturers In India

Refractory bricks or fire bricks are bricks used for kilns, ovens, and furnaces as they are able to withstand high temperatures. They are commonly made from ceramic, by adding a few other materials. They are used in a wide variety of industries, from mining and cement manufacturing to steel and aluminum production. They are also used in building and construction, as they are able to withstand extreme temperatures, such as those found in a furnace.

These bricks generally have high composition of silica and alumina, giving them high heat resistance. Most fire brick manufacturers in India incorporate more alumina into the mixture as it offers higher heat resistance. These days, they are also made from a variety of other materials, such as clay, limestone, and concrete. They are often coated with a refractory material, such as ceramic, to increase their heat resistance. Some refractory bricks are made completely from ceramics, which are more expensive than other materials, but are much better at resisting heat.

How Are Refractory Bricks Made?

Refractory bricks are made by first preparing a mixture of clay and other materials, such as limestone, which are heated to form a paste. This is then shaped into a brick and dried. The bricks are then fired at high temperatures, which causes the material inside the brick to change, making it much better at resisting heat. The bricks are then cooled and polished. Devi Lakshmi Bricks Works are the leading fire brick manufacturers in India, with a high-end manufacturing facility, making quality firebricks for every use.

Not only should the fire bricks be heat-resistant, but so should the mortar. As a result, they typically use a specialized aggregate such as vermiculite and refractory clay. Like the bricks, they can also include alumina (Al2O3), mullite-zirconia, and other materials.

Differences Between Fire Bricks & Regular Bricks

Basic Composition

Fire bricks are generally made from a higher-compressive clay, which allows them to withstand high temperatures. They are also much denser than regular bricks, which makes them better at resisting heat. They are often coated with a refractory material such as clay or ceramic, to increase their heat resistance.

Regular bricks are made from normal clay, with the addition of a few composites for strength. They are fired in a kiln too, but at lower temperatures. Their density and heat resistance is much lower than that of fire bricks.

Color, Size & Shape

Fire bricks are typically white or yellowish-white. They can be stained to form different colors as needed. Commonly found in 9 inches by 4.5 inches by 3 inches dimension. It is mostly found in rectangular shape, though all these specifications are customizable.

Regular bricks are pretty much similar to fire bricks in shape and size, but they are generally found in deep red or orange color.
