Tubos de rolha de cerâmica de nitreto de silício (válvulas) são ideais para várias aplicações devido à sua alta densidade, resistência a altas temperaturas e resistência ao choque térmico. Comparadas ao titanato de alumínio e cerâmicas de alumina, as cerâmicas de nitreto de silício oferecem resistência superior à abrasão, garantindo impermeabilidade de longo prazo. Sua resistência a altas temperaturas garante operação estável sob uso frequente, enquanto sua propriedade de não molhamento minimiza a contaminação por escória e alumínio 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.
