Preparation method of molten steel filter screen for casting
The invention discloses a preparation method of a molten steel filter screen for casting, and belongs to the technical field of casting materials. The prepared molten steel filter screen is prepared from high-temperature-resistant ceramic fibers by warp knitting and impregnation in a glue solution, and has stronger impact resistance than a molten iron filter screen. The molten steel filter screenprepared with the preparation method disclosed by the invention can be used for effectively removing harmful impurities such as bubbles, ash inclusion oxides and various inclusions in metal melt and stabilizing the flow of the metal melt, so that air holes, slag holes and sand holes of castings are fundamentally eliminated as much as possible, the yield of the castings is greatly increased, and the quality of the castings is improved.
本发明公开了一种铸造用钢水过滤网的制备方法，本发明属于铸造材料技术领域，制备的钢水过滤网由耐高温陶瓷纤维经编浸渍胶液制成，比铁水过滤网拥有更强的抗冲击性，本发明公开的制备方法制备的钢水过滤网能有效去除金属熔体中的气泡、夹灰氧化物以及各种夹杂物等有害杂质、稳定金属熔体流量，从而从根本上尽量消除铸件的气眼、渣眼、砂眼，大大提高铸件的成品率，改善铸件质量。
