A slide gate plate, also known as a slide gate refractory, is a component of a steelmaking refractory system that is used to control the flow of molten metal through a tundish into a mold during continuous casting. The composition of a slide gate plate can vary depending on the specific requirements of the steelmaking process, but generally, it is made up of a combination of refractory materials and binders.
The refractory materials used in slide gate plates can include high alumina, zirconia, magnesia, and carbon. High alumina is commonly used as it has excellent thermal shock resistance and good corrosion resistance. Zirconia is used for high-temperature applications due to its high melting point and chemical stability. Magnesia is used for basic steelmaking applications due to its high resistance to basic slag. Carbon is used for applications where high thermal conductivity and low thermal expansion are required.
The binders used in slide gate plates can include phenolic resin, waterglass, and colloidal silica. These binders are added to the refractory materials to improve their strength and prevent cracking during use.
In summary, the composition of a slide gate plate can include a combination of refractory materials such as high alumina, zirconia, magnesia, and carbon, along with binders like phenolic resin, waterglass, and colloidal silica. The specific composition will depend on the specific requirements of the steelmaking process.
