Preparation method for low-cost long-service life special-shaped billet continuous casting tundish turbulence controller
The invention relates to a preparation method for a low-cost long-service life special-shaped billet continuous casting tundish turbulence controller. The preparation method comprises the following steps that a sleeve core is arranged in an outer shell of a turbulence controller in a sleeved mode, the longitudinal centerline of the sleeve core is ensured to coincide with the longitudinal centerline of an inner cavity of the outer shell, sintered magnesite with the particle size less than or equal to 1 mm is adopted to fill the bonding joint between the outer shell and the sleeve core, and theouter surface of the bonding joint is coated with a layer of renewable magnesia carbon coating material with the thickness of 25-35 mm, curing is carried out naturally for 1-2 days, wherein the sleevecore takes a waste magnesia carbon brick renewable particle material as a main raw material and is prepared by using an isostatic pressing forming method. The waste magnesia carbon brick renewable particle material is used as the main raw material, preparation is carried out by using the isostatic pressing forming method, and the performance requirements of the metallurgical functionalization, the long service life and the low cost are met.
本发明涉及一种低成本高寿命异形坯连铸中间包湍流控制器的制备方法，将套芯套装于湍流控制器的外壳内，保证套芯的纵向中心线与外壳内腔的纵向中心线重合，外壳和套芯之间的结合缝采用粒度≤1mm的烧结镁砂填实，并在其外表面涂抹一层厚度为25‑35mm的再生镁碳质涂抹料，自然养护1～2天，所述套芯以废镁碳砖再生颗粒料为主原料，采用等静压成型法制成。以废镁碳砖再生颗粒料为主原料，采用等静压成型法制备，满足了冶金功能化、长寿化和低成本化的性能要求。
