Product description

The Monolithic Stopper is a refractory material used in high-temperature smelting processes such as steel, aluminum, and copper. It is mainly used in the casting process in metal smelting furnaces to control metal flow and maintain stable pressure in the furnace. It is widely used in steel smelting furnaces, aluminum molten furnaces, copper molten furnaces and other equipment.

Features

Excellent thermal shock stability
The Monolithic Stopper can withstand rapid temperature fluctuations without cracking or flaking. This feature is due to its unique microstructure and material composition, which ensures stable performance in environments with rapid temperature changes.

Excellent high-temperature performance
Our products use high-quality refractory raw materials and can work stably in high-temperature environments up to 1600°C to 1800°C. Secondly, our products are about 25% more durable than traditional refractory plugs under high-temperature conditions.

Strong mechanical strength
Our products have high compressive strength and can withstand the extreme pressure generated during the smelting process. Secondly, the compressive strength of our products is 15%-20% higher than that of traditional plug materials.

Excellent corrosion resistance
The chemical stability and corrosion resistance of our products make them excellent in environments where molten metal, gas and other chemical media in the smelting process are highly corrosive to refractory materials. And compared with traditional materials, our products have an approximately 20%-25% higher corrosion resistance, which can reduce production accidents and downtime losses caused by corrosion.
