Choosing the lime stone carefully as raw materials with the alumina,Smelt and make and fetch the grog through the electric are furnace(EAF),and then rubed and made the finished product thinly,Fine early intensity,the broad scope of application,steady coagulation time,make it become the first-selected brand Castable Refractory producer both at home and abroad.
