1.high temperature strength 2.anti-erosion and anti-spalling 3.Synchronization good 4.widely used in the converter lining,etc
Magnesia carbon brick series produced in SUNAI adopt fused magnesia and natural flake graphite as the main raw material and Phenolic resin as binder. According to products use and customer requirements on product quality and performance, we respectively use 630t, 1000t and 1250t vacuum brick machine to arrange production. The products are of high temperature strength, corrosion resistance, anti-stripping and good synchronization. And they are widely used in the converter lining, furnace lining slag line, trunnion and some hot parts.
