What is a straight fire brick?

It is the most widely used piece for building and lining furnaces, boilers and industrial equipment. The standard rectangular shape makes laying easy and gives firm, well-aligned walls and floors.

Being a dense brick, it works in direct contact with flame and hot gases, resisting impact, abrasion and heating and cooling cycles.

Key features

  • High heat resistance. From 1,200 °C to 1,600 °C.
  • High density. Robust, with a long service life.
  • Mechanical strength. Withstands impact and load in continuous operation.
  • Durable. Keeps its properties after heating and cooling cycles.
  • Chemical stability. Resists gases and substances released in combustion.
  • Cost-effective. Fewer replacements and maintenance stops.

Applications

Industrial furnacesCeramics, steel, metallurgy and food production.
BoilersLining of boilers in plants and industrial heating systems.
FoundriesIntense heat and contact with molten metal.
Grills and pizza ovensFrom home grills to pizzeria and bakery ovens: a robust structure for constant use.
