details


• Compared with Aluminum Titanate and aluminum oxide ceramics, Silicon Nitride Ceramics have better wear resistance and can ensure the air tightness of Stopper Tube (valve) for a long time;

• The high temperature strength of Silicon Nitride Ceramic is excellent, which can ensure that the Stopper Tube (valve) can still operate stably for a long time under the condition of frequent operation;

•  Low wettability with molten aluminum, reduced slagging and no pollution to molten aluminum.

Precautions for Use

• When installing the machine for the first time, please adjust properly between the plug rod and the valve seat;

•  For safety, the product should be dried and preheated above 400 before use;

•  In view of the brittleness of ceramic materials, it is necessary to avoid serious mechanical impact, so it is necessary to be careful in the design and commissioning of the lifting transmission device
