Erosion three air valve mainly bear high speed airfiow carrying dust erosion and the "base", the three air valve preform good integrity.convenient installation and repair replacement. Pre production, on-site installation, can fully guarantee the quality of construction.Recommend the use of corundum mullite high-strength wear-resistant preform.
1.the use of materials: silicon carbide,corundum, mullite;
2.age:1.5-3 years;
3.product characteristics: the main characteristics of the preform is body mold and heat-resistant steel and refractory castable close bond, form a whole, and after the pre baking, therefore has better integrity. Lining with corundum, fused mullite, high grade bauxite aggregate and special wear-resistant materials, and add a special additive proportion numbor,ramming vibration molding, so the product with high strength, wear resistance, corrosion rosistance, impact resistance and good thermal shock resistance，excellent,excellent spaling rosistance and crack resistance，long service life,and convenient construction, safe and reliable, greatly shorten the construction period.
