Stopper
Heads and Nozzles
Century
Stopper Heads and Nozzles are manufacturered with the latest
technology and are the correct answer to the developed casting
methods and metallurgical techniques.
Century Stopper Heads and Nozzles are completely versatile and are specially developed for the most arduous conditions. They are composed of very superior refractory materials, which give it excellent properties that are absolutely essential for a consistent performance.
Special Features
¬
Resistance to Thermal
Shock - they can withstand sudden
changes in temperature because of their low porosity, high carbon content , and low
thermal coefficient of thermal expansion. They will not crack or spall.
¬
Resistance to High
Temperature -they can tolerate
high temperatures and perform most efficiently in them.
¬
Low
Thermal Conductivity.
¬
Low
Wettability - the do not allow the slag or molten metal to
stick to the body at any temperature.
¬
Resistance To
Corrosion - they can withstand corrosion and have excellent
dimensional stability.
¬
High
Mechanical Strength.
¬
High
Refractoriness of Body.
