Main trends in the development of slide-gate systems

This article examines the three stages in the development of slide-gate systems. The modern slide gate is characterized by the presence of elastic elements and reliable fastening of the plates. Different methods are discussed for securing the refractory plates in the carriage of the slide gate. Reliable operation of the gate is provided by the drive and auxiliary elements designed with allowance for the specific features of the casting of metal with the use of slide gates. Hydraulic drives have proven to be the most effective drives in Russia and abroad. The article also discusses the shapes of refractory slide-gate plates that help reduce crack propagation and make the plates more reliable in service. The latest generation of slide-gate plates is now in wide use, these plates being made with carbon-based, oxygen-free, or cermet binders.
