Alumina hollow sphere castable

Alumina hollow sphere castable The biggest characteristic of alumina hollow sphere castables is high softening temperature, high strength and good heat insulation performance. Alumina hollow sphere castable service temperature is generally between 1600 °C and 1700 °C. Alumina hollow sphere castable is an ideal thermal insulation material for carbon black reaction furnace and high temperature special inner liner. Alumina hollow sphere castable has been widely used in high-temperature and ultra-high temperature furnaces such as petrochemical industrial gasifiers, carbon black industrial reactors, metallurgical industrial induction furnaces, etc., and has achieved very satisfactory energy-saving effects.

Neutral Ramming Mass

图片
Neutral Ramming Mass Neutral Ramming Mass Neutral ramming mass is able to resist penetration & protrusion of cracks & pores into the refraction lining, thus providing safety from penetration of molten steel towards the heat sensitive crucible & neutral ramming mass also ensures easy removal while replacing the lining. With a specific ability of sintering only on the surface, that is in contact with the molten steel. Neutral ramming mass has a series of advantages such as erosion resistance, strong stability, non-cracking, strong operability and high fire resistance.
