Fire Clay Bricks

Fireclay brick manufacturers

Fire Clay Bricks, valued for their ability to withstand heat, have long been an vital component in industrial and building settings. Fire Clay Bricks are essential for protecting buildings from extremely high or low temperatures, whether they are used in kilns, fires, furnaces, or stoves. However, what precisely makes them so important? From their composition to its numerous uses, this article examines the many facets of fire clay bricks.

  • Tremendous resistance to corrosion and wear
  • Outstanding thermal shock resistance
  • Strong resistance to spalling
  • High mechanical strength
  • Stable volume even at high temperatures
  • Superior thermal performance and resistance to acids

Brief Introduction

Fire clay brick is manufactured from clinker clay through a process of mixing, shaping, drying, and sintering. It is known for its excellent resistance to corrosion and wear, strong thermal shock resistance, good spalling resistance, high mechanical strength, and stable volume at high temperatures.

Application

  • Construction: Fire clay bricks are commonly used in fireplaces, ovens, and chimneys in homes and commercial buildings.
  • Steel and Iron Industries: The steelmaking industry depend on on fire clay bricks for furnace linings due to their ability to endure extreme heat and slag corrosion.
  • Glass and Ceramics: Kilns used in glass and ceramics production require high temperatures for long periods.
  • Power Plants: In power plants, fire clay bricks are used to line boilers and other high-temperature environments, ensuring the safety and longevity of equipment.
  • Chemical Plants: The chemical industry often exposes materials to corrosive substances, but fire clay bricks are highly resistant to chemical attacks, making them a reliable choice for these environments.
Alumina Bricks

Classification

Fireclay bricks, with an alumina content ranging from approximately 28% to 45%, are categorised into four categories: Low Duty Fireclay Bricks, Medium Duty Fireclay Bricks, High Duty Fireclay Bricks, and Super Duty Fireclay Bricks. Detailed information on each type is provided below.

  • Low Duty Fire Clay Bricks:

Content: Low duty fire clay bricks typically have an alumina content of around 28% to 30%.

Working Temperature: These bricks can withstand working temperatures up to approximately 1,100°C to 1,200°C (2,012°F to 2,192°F).

Application: Mainly used for fireplace, chimneys, and also used as back up bricks.

  • Medium Duty Fireclay Bricks:

Content: Medium duty fireclay bricks contain around 30% to 35% alumina.

Working Temperature: These bricks can endure working temperatures between 1,200°C to 1,400°C (2,192°F to 2,552°F).

Application: Mainly used as backup linings, and also for lower-temperature ceramic kilns and chimneys.

  • High Duty Fireclay Bricks:

Content: High duty fireclay bricks from Horizon Refractories typically have an alumina content ranging from 35% to 40%.

Working Temperature: These bricks can withstand working temperatures of up to 1,400°C to 1,500°C (2,552°F to 2,732°F).

Application: Widely used for boilers, ceramic kilns, chimneys and back-up linings.

  • Super Duty Fireclay Bricks:

Content: Super duty fireclay bricks contain a high alumina content, typically between 40% and 45%.

Working Temperature: These bricks can withstand extremely high temperatures, up to 1,500°C to 1,600°C (2,732°F to 2,912°F).

Property: good strength, refractoriness, volume stability at high temperatures, superior resistance to cracking or spalling during rapid changes of temperature.
