Embodiment 1

[0038] A compound turbulence controller for continuous casting tundish, the structure is as follows figure 1 , including a shell 2, a bottom plate 6, a sleeve core 4, an expansion joint 3, and an anti-oxidation coating 5. The bottom plate 6 is positioned on the bottom of the inner cavity of the shell 2, the bottom of the sleeve core 4 is positioned on the bottom plate 6, and the sleeve core 4 The longitudinal centerline coincides with the longitudinal centerline of the inner cavity of the casing 1, and an expansion joint 3 is provided between the casing 2 and the bottom plate 6, and between the casing 2 and the sleeve core 4, and an anti-oxidation coating 5 is applied on the outer surface of the sleeve core 4.

[0039] The casing 2 of the composite turbulence controller is cast and molded with magnesium castables. The bottom plate 6 of the composite turbulence controller is built with machine-pressed MT-14 magnesia-carbon bricks, and its length, width, and height are 300mm, 15...

Embodiment 2

[0053] Embodiment 2, as described in Embodiment 1, the difference is:

[0054] The thickness b of the bottom of the composite turbulence controller is 65 mm; the sleeve core 4 of the composite turbulence controller adopts machine-pressed "fan-shaped" magnesia-carbon bricks to build the side wall of the sleeve core 4, which is divided into upper and lower parts. Ring magnesia-carbon brick masonry, the height h of the "fan-shaped" magnesia-carbon brick is 100mm, and the thickness L of the "fan-shaped" magnesia-carbon brick is 100mm; the material used as the expansion joint is refractory asbestos cloth, and the thickness n is 2.0mm; The anti-oxidation coating is made of an anti-oxidation magnesia-chromium carbonaceous smear material, and the thickness c is 15mm.

[0055] The preparation method of the compound turbulence controller of the continuous casting tundish comprises the following steps:

[0056] (1) The tire mold 1 of the composite turbulence controller shell 2 is prepar...

Abstract

The invention relates to a production method of a continuous casting tundish combined turbulence controller. The combined turbulence controller comprises a housing, a bottom plate, a cartridge core, expansion joints, and an anti-oxidation coating. The housing is made of magnesia castable by casting. The bottom plate is built with magnesia carbon bricks made by mechanical pressing. The cartridge core is built with sector magnesia carbon bricks made by mechanical pressing. One expansion joint forms between the housing and the bottom plate, and the other one forms between the housing and the cartridge core. The outer surface of the cartridge core is coated with the anti-oxidation coating. The parts, such as the housing, the bottom plate and the cartridge core, of the combined turbulence controller are integrally assembled during the casting process of the housing castable; moulding bed design in the production method is simplified, assembly process is optimized, assembly quality is improved, the service life of the combined turbulence controller is prolonged, and continuous casting cost is reduced.

Description

technical field [0001] The invention relates to a preparation method of a continuous casting tundish composite turbulence controller, which belongs to the technical field of continuous casting refractory material production technology. Background technique [0002] Installing a turbulence controller in the tundish of the continuous casting machine can change the running route of the molten steel in the tundish, prolong the residence time, promote the floating and removal of inclusions, and play an important role in improving the quality of the cast slab. In recent years, in order to improve the erosion resistance and anti-scouring performance of the turbulent flow controller, the turbulent flow controller adopts a composite structure design, which is composed of shell, sleeve core, bottom plate and other components, and the shell is prepared by the production process of castable prefabricated parts. In the prior art, the preparation method of the composite turbulence control...
