Technical instructions

High aluminum silicon carbide carbon ramming material is a high proportion of granular materials and a very low proportion of the binder and other groups of distribution system, and even all of the grain, powder composition, to be beaten by the way of the construction of a strong.

Ramming materials are made of silicon carbide, graphite and electrocalcined anthracite, and add a variety of ultrafine powder additives, electric melting cement or composite resin as the dispersible materials. Used for filling furnace body cooling equipment with masonry clearance or masonry leveling. Good chemical stability, erosion resistance, wear resistance, anti - peeling, thermal shock

 

Our company has developed Al2O3-SiC-C self-flowing castables, vibration castables, ramming mixes and prefabricated blocks.

 The products are characterized by :

 densified structure,

 high strength,

 good thermal shock resistance,

 convenient installation,

 easy baking,

 good carrion and erosion resistance,

low wearing rate and high throughput of hot metal.
