AI Technical Summary
Existing fluxes, due to differences in particle size, shape, density, and surface properties during the feeding process, suffer from poor fluidity and dispersibility, are prone to accumulating, and affect the uniformity of the protective slag composition and reaction efficiency.
A flux dispersion feeding device for protective slag was designed. Using components such as rotating rollers and spiral blades, the flux is evenly dispersed in the feeding box through rotation and dispersion mechanism, and then enters the furnace through the feeding pipe to ensure that the flux and protective slag are fully mixed.
This improved the mixing uniformity and reaction efficiency of the flux and protective slag, ensuring the uniformity of the protective slag composition and the optimization of the metallurgical process.

TECHNICAL FIELD
[0001] The utility model belongs to the technical field of protection slag feeding technology, and specifically relates to a protection slag flux dispersing type feeding device. BACKGROUND
[0002] The protection slag is a synthetic slag covered on the surface of molten steel in the pouring process, and is mainly used for stabilizing the pouring operation and improving the quality of the steel surface. In the continuous casting process, the main functions of the protection slag include heat insulation, air insulation to prevent secondary oxidation of the molten steel, purification of the steel-slag interface, lubrication of the shell and improvement of the solidification heat transfer. In use, the flux is usually added to the protection slag in order to reduce the melting point and viscosity of the protection slag, thereby optimizing the performance of the protection slag in the metallurgical process.
[0003] At present, the flux is usually conveyed to the production line or mixing equipment (furnace) of the protection slag through conveying equipment (such as a conveying belt, pipeline, etc.) during feeding.
[0004] However, there are still some disadvantages in actual use. More obviously, the flowability and dispersibility of the flux are affected by the particle size distribution, shape, density and surface properties of the flux during the feeding process, which easily causes the flux to form a pile during the feeding process, so that the flux cannot be fully mixed with the protection slag, resulting in uneven composition of the protection slag and reduced reaction efficiency of the protection slag. Therefore, we propose a protection slag flux dispersing type feeding device. UTILITY MODEL CONTENTS
