摘要: 传统保护渣一般属于牛顿流体，其黏度往往是一个恒定的值，在连铸生产中具有一定的局限性。为了满足高速连铸对保护渣性能的需求，急需研制一种具有剪切变稀性质的非牛顿流体保护渣。研究发现，通过向CaO-SiO2-Na2O系保护渣中加入一定含量的B2O3或Si3N4可以使保护渣产生一种剪切变稀特性。本文从非牛顿流体保护渣的制备和保护渣微结构的检测分析两个角度开展了研究，尝试从更深层次解释产生这种剪切变稀性质的原因。
Abstract: Most traditional mold fluxes are Newtonian fluids, and their constant viscosity has certain limita-tions in continuous casting. A new non-Newtonian fluid mold flux with shear-thinning behavior is required to satisfy the mold-flux performance requirements for high-speed continuous casting. The addition of a certain amount of B2O3 or Si3N4 to a CaO-SiO2-Na2O-based mold flux can result in a shear-thinning property. In this paper, the preparation of non-Newtonian fluid mold flux and the detection of the microstructure of the mold flux were studied, and the reason for the shear thinning property was tried to be explained in a deeper level.
