Description

technical field [0001] The invention belongs to the technical field of continuous casting mold flux viscosity measuring instrument, and in particular relates to a high temperature viscosity measuring instrument for continuous casting mold flux. Background technique [0002] Viscometer is mainly used in the viscosity measurement of continuous casting mold flux. The main functions of continuous casting mold slag are as follows: First, isolate the contact between air and molten steel, block the secondary oxidation of molten steel, block the contact between the carbon-rich layer and molten steel, avoid carbonization on the surface of the slab, and improve the surface quality of the slab , which reduces the loss of steel. Note: Carbon addition to the surface of low carbon steel and ultra-low carbon steel will produce brittle blanks. Second, absorb molten inclusions (system refractory materials, metal inclusions such as deoxidized products), and protect its own performance from c...
