Production method of metering nozzle for steelmaking tundish made of zirconium oxide composite material
The invention provides a production method of a metering nozzle for a steelmaking tundish made of a zirconium oxide composite material. The production method comprises the following steps: granulating titanium nitride fine powder to obtain titanium nitride particles; mixing the titanium nitride fine powder, the zirconium oxide fine powder, the titanium nitride particles, the mixed powder and the binding agent; molding in a mold; drying the formed product; and heating the dried product in an inert atmosphere to obtain the required product. According to the production method of the zirconium oxide composite material sizing nozzle for the steelmaking tundish, the problem that the high-temperature firing yield of the zirconium oxide material sizing nozzle is low due to crystal form transformation of zirconium oxide is solved; in order to solve the problem that the nozzle is often exploded during use, the titanium nitride fine powder is introduced, and the activity of the titanium nitride fine powder is utilized, so that the sintering performance of a product is improved, and the crystal form of zirconium oxide is stabilized, thereby obtaining the sizing nozzle with high strength, high melting point, high thermal stability and high corrosion resistance to metal and steel slag.
本发明提供了一种氧化锆复合材质炼钢中间包用定径水口的生产方法，包括以下步骤：氮化钛细粉造粒得到氮化钛颗粒；将氮化钛细粉、氧化锆细粉、氮化钛颗粒、混合粉、结合剂混合；模具中成型；将成型的制品干燥；将干燥后的制品在惰性氛下加热，得到所需产品。本发明的氧化锆复合材质炼钢中间包用定径水口的生产方法解决了氧化锆材质的定径水口由于氧化锆的晶型转化，导致高温烧成成品率低；在使用时经常发生水口炸裂的问题，通过引入氮化钛细粉，利用氮化钛细粉的活性，提高了制品的烧结性能，稳定了氧化锆晶型，从而得到一种高强度、高熔点、高热稳定性、对金属和钢渣具有高抗侵蚀性的定径水口。
