Chromium stuffing sand covered by siliceous coating and preparation method thereof
The invention discloses a siliceous coating-covered chrome stuffing sand. The original materials comprise chrome corundum, tabular corundum particles, silicon oxide micro powder, crystalline flake graphite and carbon micro powder; adding a high-temperature binder and water, stirring in batches, drying, and uniformly mixing and stirring to obtain the siliceous coating covered chromium stuffing sand. According to the flow guiding sand covered with the siliceous coating, the siliceous material covers the surface coatings of the chromium ore and the tabular corundum, the liquid phase amount generated in the using process of the flow guiding sand is adjusted and controlled, the automatic casting rate is increased, and the problems that traditional flow guiding sand is unstable in performance and not prone to casting can be solved through the method; according to different smelting modes, the covering amount of the siliceous micro powder can be regulated and controlled, then the formed liquid phase amount is regulated and controlled, the sintering degree is controlled, the automatic casting rate is improved, and a sintered body with certain strength is more easily formed.
本发明公开了一种硅质涂层覆盖的铬质引流砂，原始料为：铬刚玉、板状刚玉颗粒、氧化硅微粉、鳞片石墨、炭质微粉；外加高温粘结剂和水，通过分批次进行搅拌、干燥、再混合搅拌均匀获得硅质涂层覆盖的铬质引流砂；本发明提供的硅质涂层覆盖的引流砂，通过在铬矿砂及板状刚玉表面涂层覆盖硅质材料，调控引流砂使用过程中产生的液相量，提高自动开浇率，本方法能克服传统引流砂性能不稳定，存在不易开浇的问题；能够针对不同冶炼方式，调控硅质微粉的覆盖量，进而调控形成的液相量，控制烧结度，提高自动开浇率，更易形成具有一定强度的烧结体。
