Refractory vermiculite insulation board for steel ladles with high temperature resistant and low thermal conductivity

Description of Vermiculite Brick

BWV Vermiculite board

Bluewind Vermiculite Light-weight insulating brick is made from non-asbestos expanded silver vermiculite and inorganic fillers to

give a uniform and controlled pore structure. The brick is compressed and sintered under high temperature. Bluewind Vermiculite
Insulating Firebrick is widely used as transition refractory lining or back-up insulation in various kinds of industrial furnaces,
helps improve the service life and better insulation performance.

Metallurgy Insulation Layer

Bluewind TRI series aluminum silicate plate, can resist max 1,200 Celsius degree firing, and the thermal conductivity below 0.3 W/m.K. Which in steel melting industry, it has been applied in the liquid ladle and tundish as the insulation layer, for the properties of high temperature resistant and thermal insulation.

Thickness: Commonly applying 10/15/18/32 mm plate as the transition layer or insulation layer.

Performance: Can keep the outside temperature as designed.

Service Life: Expected to serve for 10 months or longer ( the refractory layer requires refurbished regularly)

Shapes: Rectangle or trapezoid

Installation: Past to the inside wall of ladle with refractory clay; then install the permanent layer, and last refractory layer
