Aluminum silicate plug is sometimes called outlet furnace mouth insulation plug, insulation cap and insulation plug.

It is mainly made of high-grade aluminum silicate fiber and other formulas through vacuum molding,

It is suitable for heat preservation and sealing at the outlet of aluminum, copper and zinc smelting furnaces, refining furnaces and static furnaces, making the casting process of aluminum, copper and zinc alloys more convenient, safe and reliable.
