Aluminum silicate cotton stopper

Made of alumina silicate ceramic refractory cotton, vacuum-molded in one piece, with a conical structure, this high-temperature resistant insulating plug is distinct from hard graphite plugs.

Used for sealing the aluminum outlet of aluminum smelting furnaces and stationary furnaces; for furnace shutdown insulation, blocking the outflow of molten aluminum, and suitable for hot-top casting production lines.

Advantages

1. Strong thermal insulation: Low thermal conductivity, minimal heat loss from the furnace opening, reducing aluminum molten temperature drop and burn-off;
2. Non-stick to aluminum, no impurities: Molten aluminum does not wet the surface, no carbon contamination, fewer inclusions and pores in the cast billet;
3. Lightweight and elastic: Fits tightly to the furnace opening, easy to disassemble and drill;
4. Thermal shock resistant and crack-resistant: Not easily broken by rapid heating and cooling, withstands high temperatures up to 1260℃;
5. Disposable consumable: Low price, easy replacement, no repair or maintenance required.
