STANDARD DENSE CASTABLES & GUNNING MIXES
VITCAST 1550 STD & GUN MIX
VITCAST 1600STD & GUN MIX
Bauxite based, dense, hydraulically bonded castable which has a high strength and abrasion resistance for temperatures up to 1550 O C. Examples of Applications: Used in a range of applications in iron and steel, foundries and boilers in vulnerable areas such as doors, sills and lintels, where strength and abrasion resistance is important.
Chamotte based castable refractory with low iron content for use at temperatures up to 1600 O C in direct contact with flame in oxidising or reducing atmospheres. Examples of Applications: Used in burner quarls, for lining repairs as a patch material and for making panels in incinerators.
