Introducing the Stopper Rod - a durable refractory material rod that is designed to control the opening and closing of water outlets and steel flow in steel drums. Also known as a ceramic stopper rod, it is made up of a rod core, sleeve brick, and stopper head brick. The rod core is typically made from carbon steel round bar with a diameter of 30-60mm and is connected to the lifting mechanism's cross arm using bolts. The lower end is connected to the stopper head brick using threads or pins, while the middle is fitted with a sleeve brick. The stopper rod must be carefully constructed and baked for at least 48 hours to prevent refractory material from exploding and causing steel leakage accidents. Trust the Stopper Rod for reliable and safe steel production.
