Anti-blocking submersed nozzle for special steel continuous casting and preparation method of anti-blocking submersed nozzle
The invention discloses an anti-blocking submersed nozzle for special steel continuous casting and a preparation method of the anti-blocking submersed nozzle. An anti-blocking submersed nozzle for special steel continuous casting comprises a main body, the main body is composed of a heat conduction layer and a heat insulation layer which are sequentially connected from inside to outside, and the heat conduction layer makes contact with molten steel; wherein the heat conducting layer is prepared from the following raw materials in percentage by weight: 60-80% of fused corundum, 4-11% of silicon carbide, 14-25% of aluminum nitride and 2-4% of boron nitride; an adhesive is added into the heat conducting layer; the heat insulation layer is prepared from the following raw materials in percentage by weight: 65 to 75 percent of fused alumina, 5 to 8 percent of mullite, 6 to 11 percent of glass fiber and 14 to 16 percent of silicon nitride; and a binding agent is added into the heat insulation layer. Through cooperation of the heat conduction layer and the heat insulation layer, the anti-nodulation performance of the submersed nozzle can be remarkably improved, and the number of continuous casting furnaces for titanium-containing steel reaches up to 16 or above.
本申请公开了一种特种钢连铸用防堵塞浸入式水口及其制备方法。一种特种钢连铸用防堵塞浸入式水口，包括主体，所述主体由内向外依次相连的导热层和绝热层组成，所述导热层与钢液接触；其中，所述导热层由如下重量百分比的原料制得：所述电熔刚玉60～80%、碳化硅4～11%、氮化铝14～25%、氮化硼2～4%；所述导热层中加入粘接剂；所述绝热层由如下重量百分比的原料制得：所述电熔刚玉65～75%、莫来石5～8%、玻璃纤维6～11%、氮化硅14～16%；所述绝热层中加入结合剂。本申请通过导热层和绝热层的配合，能够显著改善浸入式水口的抗结瘤性能，对含钛钢材的连铸炉数高达16炉以上。
