Refrractory Monolithic Stopper Rod For Steel Making
Product Details

The monolithic stopper rod  is used for steel flow controling in tundish , controlling the rod  head to tundish nozzle   to regulate the molten  flow entering the mould , and also can blowing argon through stopper central hole  to submerged nozzle , avoid nozzle  block. The traditional stopper rod is combined type. Due to its many seams, the molten steel and slag are easily immersed in the seam which can cause stopper broken  or the plug head  falling off, leading to accident.

The high performance monolithic stopper  produced  by our company  connected  stopper body and head  without seams. It has good corrosion  and erosion resistance to molten steel and slag, good anti-flaking property, no chipping during use, good thermal shock resistance, no pollution to molten steel, high mechanical strength. It can effectively reduce the blockage of nozzle and improve production capacity.
