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.
Features
High crushing strength Excellent thermal shock resistance Low thermal conductivity Low heat storage Long service life
Corrosion resistant
Non-combustible
Environmental friendly
Lower emission
Accurate and customized dimension
Foundry Ladle
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
