Silica fume for converter refractory materials
Product description
Silica fume for ceramics has excellent flow characteristics and very high activity, which can fill the voids and defects in refractory materials and improve the compactness and hardness of the materials. At the same time, the silica fume reacts to form a high-strength silicate phase, which greatly enhances the compressive strength and abrasion resistance of the material. Reducing the rate of burnout
Silica fume, as an important refractory additive, has strong resistance to high temperatures and corrosion, and is able to reduce the burnout rate of refractory materials at high temperatures and under extreme conditions. At the same time, silica fume participates in the hardening and consolidation reaction of the refractory material, improving its integrity and resistance to spalling and increasing its service life. Enhanced hardness and compressive strength
Improvement of thermal insulation properties
Silica fume has a very low radiation effect and heat conduction coefficient, so it can effectively improve the heat insulation performance of refractory materials. In high temperature working conditions, the silica fume can achieve the thermal insulation of refractory materials, avoiding the problems of cracking and burning caused by the rapid increase in the temperature of refractory materials.
