FIRE BRICKS

Fire Bricks

MHD / HHD Bricks :(30 - 32% / 38 - 40% Alumina )


These are general - purpose firebricks made from selected grades of raw and calcined fire clay and fired to suit the customer's application.

Superduty Bricks :(43 - 45% Alumina)

Superduty bricks are made from a combination of superior grades of calcined clays and calcined kyanite. Very pure, low porosity bricks with exceptional hot strength suggested for glass regenerator and steel making applications.

Bauxite Based Bricks: (45-80% Alumina)

Mani, factured from calcined indigenous / imported bauxite. These bricks are the most economical solution in their alumina class. Especially noteworthy are the 70% to 80% Alumina class which has proven their nerve in steel ladles and cement rotary kilns.

Sillimanite : (58-60% Alumina)

This is by far the most versatile range of high alumina refractory shapes & straigth Vindyawasini Refractories portfolio. Extra pure dense grades with very high mullite Content are ideal solutions for Glass plant, Blast furnace Stove and stack and other demanding applications a where as Dutta Co - SILL is the economical low iron alternative for applications up to 1700°C.
