The high-strength alkali-resistant refractory castable has good resistance to alkaline gas and slag, and has a long service life. High strength alkali resistant castable is mainly used for lining of other industrial furnaces such as kiln door cover, decomposition furnace, preheater system and pipeline system.

AI203-Mg0-C bricks:This series of products are made from corundum, magnesium aluminate spinel, super-grade bauxite, high quality MgO and graphite as main raw materials and phenolic resin as binder.
Using high quality magnesia as the main materials, by adding compound binding additives, this series of gunning mixes for EAF feature high adhesive strength, low rebound rate, good sintering, good erosion resistance, and can be used as cold or hot repair materials at slag line and side wall.
Nobaking ramming mass for iron notch is made of corundum, high quality bauxite and silicon carbide, and bonded by resins and tar. Installation can be done by ramming.
