Precast Shapes From Conventional Castables
Conventional Castables with 45 - 95% Alumina and different purity levels are used in making high grade precast shapes. They have high strength and good resistance to thermal shocks and also withstand high temperatures and abrasion resistance. They are made to any shape or size.
Xtral special shapes are used for applications in all the industries totally replacing shaped blocks in category of firebricks.
