Made by using sintered alumina and mullite as raw material, add in some of the carbon matrix components and anti-oxidant(such as aluminum, silicon metal, SiC, B4C, Mg-B and so on), adding binder pitch or phenolic resin mixed with coal Nerishige type, fired in a reducing atmosphere to form alumina oxide carbon refractories sliding gate plate.Slide plates fired at high temperatures cover Al2O3-C based, Al2O3-ZrO2-C based and MgO-spinel based, Our company supports the customer in flow control offering a range of ladle slide gate products. We have a wide range of refractory materials for achieving consistent and reliable high performance in all areas of slide gate applications. Balanced refractory life of plates, nozzles and well blocks enables a cost-effective operation
