Self flowing castables/For industrial kilns/Easy installation, good anti-spalling and thermal shock resistance
Product description:
Using high quality bauxite and mullite as the main materials, the ultrafine powder bonded low cement castables for furnace lining are characterized with good flow ability, easy installation, good anti-spalling and thermal shock resistance, low thermal expansion, and good thermal insulation. The products can be widely used at roof, wall and bottom for industrial furnaces.
Self flowing castables
With vibrating-free or lightly vibrating, these castables can degas and densificate by self-gravity.These products can ban installed by pumping,and characterized with high strength and good thermal shock resistance.
Category of Refractory Castable:
Features:
They are characterized with good installation, excellent slag erosion resistance and thermal shock resistance, and gain good performance.
