Product introduction
The stopper rod is a refractory material rod which is installed in the heavy steel barrel and controlled the opening and closing of water outlet and the flow of molten steel by lifting displacement, also known as ceramic plug rod. It is composed of rod core, sleeve brick and plug head brick
Product Feature
1, Using advanced naked burning technology, sprinkler head can avoid baking and replacing the use of multiple furnaces, with good thermal shock stability and scouring resistance
2, Low carbon long nozzle can meet the requirements of long life
3, The composite carbon free lining can guarantee the special requirements of clean steel, ultra-low carbon steel and so on..
4, The composite zirconium-carbonaceous slag line has better slag erosion resistance.
5, High strength anti-oxidation coating, can form liquid protective film in the range of 600~1200℃, protect carbon from oxidation, prolong the service life.
6, The air seal device with different structure can be selected according to the need at the connection with the water outlet of the big bag to prevent oxygen and nitrogen absorption effectively.
