Chromium steel jade casting material is mainly made of high-strength refractory raw materials such as corundum and chromium oxide as aggregates and fine powder, and is made by adding fine powder. Chromium steel jade casting material belongs to the composite corundum casting material series, which is a neutral refractory casting material. It is composed of coarse aggregate, fine aggregate, and powder in a fixed proportion, and is added with a certain amount of binder and admixture. This material is suitable for casting construction. Add binder, accelerator and proper amount of water during construction, and mix it to make castable with good fluidity. When using, the ratio of coarse, medium and fine aggregates and powders to the binding agent can be adjusted as needed. The binding agent used is pure calcium aluminate cement and phosphoric acid (or aluminum dihydrogen phosphate). , The use effect is obvious, and the service life is longer than the traditional corundum castable. The main components of chromium steel jade castables are aluminum oxide and chromium oxide. These two components can produce corundum solid solution phase under the action of high temperature. This solid solution phase has high temperature resistance, erosion resistance and wear resistance. It is used in carbon black reaction furnace, ferroalloy kiln, coal water slurry gasifier, and the effect is remarkable.
It can be used in 2000-degree high-temperature kiln, used in various high-temperature kilns such as carbon black reaction furnace, coal water slurry gasifier, incinerator, smelting furnace, steel-making furnace, glass drawing furnace
