Los tubos de tapón (válvulas) de cerámica de nitruro de silicio son ideales para diversas aplicaciones gracias a su alta densidad, resistencia a altas temperaturas y resistencia al choque térmico. En comparación con las cerámicas de titanato de aluminio y alúmina, las cerámicas de nitruro de silicio ofrecen una resistencia superior a la abrasión, lo que garantiza una impermeabilidad duradera. Su resistencia a altas temperaturas garantiza un funcionamiento estable con uso frecuente, mientras que su propiedad antihumectante minimiza la contaminación por escoria y aluminio fundido.

Product Details
Silicon Nitride Ceramic Stopper tube (Valve) is the better choice for various types of stopper tubes/valves due to its high density, high-temperature strength, and good thermal shock resistance. Compared with aluminum titanate and alumina ceramics, silicon nitride ceramics have better abrasion resistance, which ensures the better impermeability of the stopper tube/valve for a long time; The high-temperature strength of silicon nitride ceramics ensures that the stopper tube /valve can operate smoothly for a long period under conditions of frequent operation; Non-wetting property reduces slag and pollution of molten aluminum.
Mascera specializes in the research, development, and manufacturing of high-performance ceramic products, offering custom-designed silicon nitride ceramic stopper tube (valve) based on customer specifications. Equipped with advanced production equipment and a highly experienced technical team, we are capable of addressing challenging design requirements for specific operating conditions as well as stringent demands for dimensional tolerances and surface precision. We are committed to providing reliable solutions that meet and exceed customer expectations.
