Refractory Aluminum Silicon Carbide Carbon Brick Al-Sic-C ASC Brick for Mixed Iron Car
Our company's aluminum-silicon series products for torpedo cans have excellent acid and alkali corrosion resistance, alkali slag corrosion resistance, good thermal shock resistance and peel resistance. It can adapt to the different smelting conditions of various customers in the steel industry, and has the characteristics of high furnace age and low maintenance cost.
Torpedo tanks are not only subject to corrosion by ordinary molten iron, but also severely corroded by metallurgical auxiliary materials. For example, the desulfurizer is CaO-CaF2-CaC2, the desilication agent is usually fish scales or lime, and the dephosphorization agent is FeO-CaO-CaF2 or Na2CO3, which have very serious melting corrosion and oxidation effects on high alumina series refractories.
