Zirconia foam ceramic filter is mainly composed of ZrO2, with temperature resistance of 1760 ℃, very high strength and excellent high-temperature impact resistance. The square zirconia foam ceramic filter is applied to the steel castings, which effectively removes impurities such as slag and refractory fragments in the molten steel, improves the surface quality, mechanical properties and internal structure quality of the steel castings, and reduces the scrap rate.
In the casting process, zirconia foam ceramic filter can make the molten steel fill the cavity more evenly. Through the three-dimensional structure of zirconia foam ceramic filter, the turbulent flow is changed into a stable laminar flow, so as to realize the compact structure of the steel casting, improve the quality of the steel casting, reduce the impact and corrosion of the molten steel on the casting cavity, and extend the service life of the casting cavity.
