Carbon Graphite Rod Stopper

This is a set of carbon graphite rod stopper made of high-purity graphite, and their shapes can be customized as needed, mainly to match graphite crucibles. This combination mode plays an important role in high-temperature melting and casting.

The main function of carbon graphite rod stopper is to block the liquid outlet hole at the bottom of the crucible and accurately control the outflow time and flow rate of molten metal. Its typical design usually adopts a conical sealing structure: a cone with a larger upper part and a smaller lower part is inserted into the outlet, and then pressed tightly against the outlet wall by the cone to form a seal; When we lift the graphite plug rod, the molten metal will flow out at the desired pace. In some specific designs, the stopper also has a breathable function.

On the actual production line, carbon graphite rod stopper act throughout the entire metallurgical casting process. If the graphite rod plug is not tightly closed in the insulation furnace, it can cause copper water to seep out from the contact surface, leading to scalding accidents. The sealing reliability is directly related to production safety.  At the same time, it can also be used as a plug in fields such as glass and chemical high-temperature molten salt pipelines, undertaking the functions of plugging and diversion.
