Direct Bonded Basic
Fireclay Bricks or fire bricks are the most widely used refractory bricks because of its great features: low thermal conductivity, good thermal insulation performance; High resistance to Thermal shock, abrasion, chemical attack to provide long service life; easy operation and installation; broad usage or applications and low price etc.
High density with low porosity fire clay bricks is our featured product in this category. Due to its low apparent porosity rate, high density with low porosity bricks have great features of strong resistance to erosion, high refractoriness under load, great Cold Crushing strength and high mechanical strength etc.
At KRPL we offer a comprehensive range of Fireclay brick/fire bricks consisting of 20-45% Alumina all of which exhibit excellent strength.
Our bricks are highly useful in the boilers, sugar industry, steel foundry, cement pre-heater cyclone, silicate furnace, boilers incinerators, cement kiln, preheating zone and preheating furnace wall.
